Phthiriasis (pubic lice) in men: how to be?

Parasites bring a lot of inconvenience to humans. Pubic pediculosis is a common disease among both women and men. Lice affect the skin in the groin and genitals. The problem mainly concerns people who conduct unclean sexual life, since parasites are transmitted from person to person. Reproduction can begin in other parts of the body: on the eyebrows and eyelashes, in the armpits. A constant feeling of itching and burning, painful sensations is far from the entire list of signs of pediculosis that has begun.

Being on the skin and actively multiplying, pubic lice invariably cause a disease such as pubic pediculosis, otherwise phthiasis

Parasite features

What do pubic lice look like? The parasite belongs to the order of the lopsided. This is a blood-sucking insect that appears and multiplies in the inguinal region of a person. Appearance is a body of a flat shape with warty growths with a light yellow color. Claws located on the hind limbs, lice firmly cling to the hairline.

A louse goes through several stages of development during its life: an egg (nits), a nymph and an adult (adults). Pubic nits are difficult to detect. They differ in small size and flat shape. It is almost impossible to find them with the naked eye on the hairline of the inguinal region. Egg maturation occurs in 5–10 days, after which the nymph hatches. After 2-3 weeks, the louse grows to the size of a mature parasite.

The size of the insect is approximately 2 mm. It exists only in the presence of food - human blood. Outside the human body, a louse can survive no more than two days.

Symptoms of Pubic Lice Disease

Like any other similar parasite, pubic louse eats blood, and because of this, the very first and obvious symptom of the disease is the characteristic small wounds from bites on the skin. At the same time, in places where parasites accumulate, severe itching is observed, although depending on the individual reaction of each person, itching may be slightly expressed. The photo shows the consequences of parasite bites with phthyroidism (pubic pediculosis.

Very often, in the places of combing, a bloody crust forms and dandruff appears. It is worth noting that severe itching in itself is not only unpleasant, but can also cause other concomitant diseases, as an infection can get into the areas that are combed to the blood.

As a result, a person takes itching for an allergic reaction and uses the appropriate ointment (and very often does not bother to consult with doctors). As a result, some ointments sometimes stimulate the reproduction of parasites, and itching only intensifies.

Another less obvious symptom is bluish spots on the skin, which appear for the following reason: the saliva of the pubic louse contains special enzymes that destroy hemoglobin. Hemoglobin, decaying, produces decay products that have a characteristic shade and form the very blue spots (maculae caeruleae). But to notice such a spot is quite difficult, since in size it usually does not exceed the size of the louse itself.

Causes of Pubic Lice

Why does this unpleasant phenomenon occur - pubic lice? What could be the reason? To begin with, pubic lice are parasites that multiply and parasitize exclusively on the human body (on the pubis, genitals, in the anus, in the abdomen, on eyelashes, eyebrows and any other vegetation that is located on the human body). The nutrition of the parasite is only due to the blood of a person (host). If the parasite is not fed by human blood, it will die within 24 hours. As soon as the parasite gets on the man’s body (we are considering it is pubic lice in men), then this is considered the beginning of the disease.

For information!

The size of pubic lice is approximately a few millimeters. Moreover, visually the female from the male can be distinguished immediately, since they are approximately 2 times larger.

Infection with pubic lice is possible through a dirty bed (you stayed for the night in a bad hotel, with unclean friends or acquaintances). Sexually transmitted infection is also common (if partners do not follow hygiene rules).

There are known cases of infection with pubic lice through dirty towels, someone else's clothing, after visiting a bathhouse, sauna and other public places (even after visiting a public toilet).

You cannot get pubic lice from an animal, it's impossible!

Features of pubic lice

These are insects of small size - up to 3 mm. Females are noticeably larger than males. They have a flattened oval body of light brown color. Three pairs of legs are spread wide, so it seems that the width of the insect is greater than its length. Paws are long, tick-shaped. The structure allows them to move through the hair of a triangular section. On the round hairs that grow on the head, they cannot gain a foothold, so they do not live on the head.

Like other types of lice, pubic resemble several stages in their development:

  • nits - white eggs within which larvae develop, this stage takes up to a week,
  • nymphs of stages 1, 2 and 3 - in 15 - 17 days the parasite passes three molts and becomes sexually mature,
  • adults.

Pubic louse lives up to 30 days. During his life he lays about 50 eggs.

Without nutrition, the parasite lives a day. If adverse conditions occur, the pubic louse can fall into a state of suspended animation and spend several months in it. Pubic lice can live in water for up to two days. They withstand loads up to 1 kg. For example, on the beach, in the sand, they can exist for several days.

Description of the culprit of infection

Infection with pubic parasites (plaques) in medical circles is referred to as phyriasis. Infestations by the plaques are more often affected by adults and only in rare cases by children. Favorite habitats are areas in which the apocrine glands are concentrated:

  • genital area: pubis, scrotum,
  • hair near the anus,
  • armpit.

Pubic lice in men can settle in the inguinal zone, on the hairline of the abdomen, chest, and mustache. In children, the parasite settles on eyelashes, eyebrows.

The causative agent of phthiasis is the human pubic louse, which is distinguished by its tiny size. The body length of the female barely reaches 3 mm, males are even smaller - 1-2 mm, so it is almost impossible to see insects with the naked eye, as well as determine sexual dimorphism. Damsels in appearance resemble miniature crabs. Their legs are adapted to move only through hair with a triangular section, so they can not live in hair or on clothes, like other subspecies of lice, a priori.

They feed exclusively on blood at least 2 times a day. The interval between meals is no more than 12 hours. How many lice live depends on the living conditions. Without food, inguinal lice die after 24 hours. Under certain conditions, while outside the body, they can fall into a state close to suspended animation and stay in it for several months.


Pubic lice are not characterized by special mobility, are firmly attached to the base of the hair closer to the skin, immerse their oral apparatus in it and can be in one place for several days. Females lay eggs - nits. With the help of an adhesive substance they are attached to the hairs so tightly that it is not possible to wash them off with water.

Over the course of its life, a female lays about 50 eggs, which is much less in comparison with a prolific female head louse.

A week later, a young generation emerges from the eggs. Pubic lice larvae differ from their parents only in size and better survival. Without nutrition, they maintain vital activity for 7 days. Empty shells of nits continue to remain on the hairs, over time they become thinner and destroyed. For the pubic louse larva to become sexually mature and able to start mating and breeding, it takes 10 days.

Signs of pubic lice

Pubic lice have the following symptoms:

  • Itching at the bite site, which can manifest itself in different ways - from a slight feeling of discomfort to severe itching and burning day and night.
  • Purple blue spots with a diameter of 2 to 10 mm, visible to the naked eye. They are formed as a result of hemorrhages that appear at the site of a bite and parasite injection of secretion against blood coagulation.
  • An allergic reaction, expressed as a rash, redness, swelling, and tearing.
  • The appearance on the underwear of dark brown spots (excrement of parasites).
  • The presence of nits.
  • Loss of appetite, nausea and insomnia.

Pubic lice in women are less common than in men, since most of them are more responsible for genital hygiene and the choice of a sexual partner. As a rule, in women, in addition to the pubic zone, the prianal areas of the skin are affected.

The nits of the scapula (the so-called pubic louse is called differently) penetrate the external organs of the woman’s reproductive system, causing severe discomfort, expressed in itching, burning and skin rash.

Reasons and diagnosis

Pubic lice in the stronger sex occurs for several reasons:

  • Unclean sexual life. With erratic communication with random partners, pubic lice are transmitted to each other.
  • Bad living conditions. The disease can begin after visiting a public place where sanitary requirements are not observed (dirty linen or towels at the hotel, at a party, in a bathhouse, public toilet). Sometimes parasites can crawl from someone else’s clothing.

From animals, pubic lice never spreads to humans.

Pubic pediculosis in men is diagnosed after visual detection of lice in the inguinal region. Sometimes special lenses are used for inspection, because the small size of the lice complicates the procedure. If the first symptoms of the disease and signs of the presence of parasites on the body occur, you need to consult a dermatologist.

For proper diagnosis, you should make an appointment with a venereologist, as well as a dermatologist

The prevalence of pubic lice

Phthyriasis (pubic pediculosis) are a parasitic disease that belongs to the group genital infections, since it affects the genital hair, and is transmitted through close contact of a healthy person with a patient. Phytiasis refers to parasitosis. This means that the disease is caused by small parasites (lice). Pubic lice affect the genital area, axillary hollows, chest, abdomen, as well as the hair of eyebrows and eyelashes.

Pubic lice are not only a source of skin pathology, but also carry pathogens of various infections, including epidemic and dangerous ones - for example, typhus, typhoid fever, etc. In addition, if a person is infected with pubic lice, then a different sexually transmitted infection is detected in every third individual with phthiriasis.

Unfortunately, the prevalence of pubic lice in the countries of the former USSR is from 10 to 20%, depending on the area. It is not possible to completely eliminate this parasitosis due to ignoring the rules of personal hygiene by part of society, and the lack of an effective diagnosis. Many people are simply embarrassed to go to the doctor because of the stereotype that phthiasis is a dirty body disease. This is actually not the case. Pubic louse settles on any body, regardless of its purity.

An increase in the incidence of pubic lice is associated with various social shocks, accompanied by a sharp decrease in living standards, the displacement of a large number of people, etc. The greater the crowding of the population, the less satisfactory the living conditions, the higher the risk of contracting pubic pediculosis.

Possible complications

As already mentioned, due to the disease when combing damaged skin areas are formedthrough which any infection can easily enter the body and cause appropriate complications. As a result of this, pyoderma, pustular skin infections, are often observed in patients with phthiasis.

But much more serious is the inflammation of the lymph nodes, the formation of abscesses and the development of boils - all this also contributes to phthyroidism. And the worst complication that can be in this case is blood poisoning (sepsis). This occurs with weak immunity, when the body itself can not cope with pustular infections.


As soon as a person has pubic lice on his body, he still does not feel any symptoms. And only after a month the symptoms begin to manifest. The first symptom of pubic lice is unbearable skin itching. But, even at this stage, a person can not always determine and understand that he has a disease - pubic lice.

It is characteristic of pubic pediculosis that it affects the pubis, anus and places of increased hair growth. Itching is activated at night, and during the day it becomes much easier for the patient. A person begins to intensively comb the lesion, as a result of which the skin in this place turns red, irritated, covered with painful eczema. Combing the places of bites of pubic lice is categorically not recommended, as this can lead to infection.

Other symptoms of the disease

Other characteristic symptoms of the disease are:

  • Blue spots on the skin, characteristic of the disease, are up to about 1 cm in diameter (the reason for their appearance is a bite of the pubic lice and, as a result, a slight hemorrhage under the skin). These spots are very easy to notice, as they appear on the chest, abdomen, hips,
  • Allergic reaction,
  • During a visual examination of the skin, you can see white dots - these are either lice or their larvae.

Where can pubic lice be found?

As mentioned above, pubic lice live on the scalp, but not all of the hairline is affected. For them, sites with apocrine glands that secrete a special secret are attractive:

  • pubis,
  • crotch,
  • anus
  • scrotum,
  • axillary hollows.

Affected areas are always covered with hair. On smooth skin, these parasites do not live. The disease occurs in both men and women. Children can also become infected if they have hair on their genitals.

Diagnosis of the disease

The incubation period lasts about 25-30 days. When the first settlers appear, the symptoms of pubic lice do not appear. Their number is still so insignificant that a person does not experience any discomfort and does not suspect that he has wound up ectoparasites. When the lice got well settled, significantly replenished their ranks, the following symptoms of pubic lice appear:

  • the appearance of severe itching in the area of ​​infection caused by bites of lice,
  • bluish spots on the skin with a diameter of up to 1 cm, caused by a lack of hemoglobin in the affected area or the introduction of parasite saliva, which has a protein structure and contributes to the manifestation of allergic reactions,
  • tiny brown spots on underwear are another sign of the presence of blood-sucking insects in the intimate area.
Symptoms of Pubic Lice

When the disease becomes pronounced, the causative agents themselves can be found on the underwear - small lice, which are easiest to identify after they have had a meal. In this state, they acquire a brown-rusty hue. With a large accumulation of pubic parasites, itching can become intolerable, which leads to severe combing and infection in the wounds. On affected areas, pubic hair sticks together in hard bundles.

In women, intimate pediculosis is localized in the pubic area and may be accompanied by inflammation of the mucous membranes and skin. In men, in the presence of a dense hairline on the abdomen, thighs, phthiriasis extends to these areas.

Having revealed parasites, the question involuntarily arises of where the pubic lice come from. In most cases, infection occurs after close contact with the carrier. Intimacy with an infected person, contact, the use of other people's bedding are the main causes of lice on the pubis.

The insect is distinguished by its survival in water, so the possibility cannot be ruled out that phthyriasis is transmitted by water after taking a bath with the primary host of parasites. Visits to saunas, baths, beaches, overnight in a dubious hotel are other possible ways to get infected with pubic lice.

What is mandate, I know firsthand. A couple of weeks after a stormy party, I began to experience severe itching. The transmission methods, treatment methods and how to get rid of itching were eloquently described by Yura Khoy, the lead singer of the Gaza Strip group in the song “The Louse of the Louse”. Since I live in a dormitory-type hostel, where there is a shower at the end of the corridor, I did not have to think about applying any shampoos there. Therefore, I chose the most reliable and fastest tool - a razor. The method has only one side effect - a week after shaving, the same itching appears as with the appearance of parasites.

How can I get pubic lice?

Lice can be detected by visual inspection in the inguinal region. Pubic lice in men, in addition to the inguinal zone, can affect the hairline in the chest area.

It is important to know where lice come from in order to avoid their appearance. The main methods of infection are considered sexual contact with a pediculosis carrier and domestic infection, when pubic lice are transmitted to a healthy person in a bathhouse, pool, on the beach and other public places.

Infections in trains and hotels can occur due to poor sanitation of bed linen and towels.

The following categories of people fall into the risk group:

  • Hairdressers, bath attendants, workers in tanning salons, swimming pools and trains,
  • Children and employees of preschool institutions, health camps,
  • Persons living in barracks and dormitories,
  • Prisoners
  • Women of easy virtue and their clients,
  • Homeless people and tramps.

Symptoms of the disease

When lice first appear on the body, a person does not have any symptoms. But after a month, when a mature louse grows out of the nits, the symptoms of pediculosis will begin to appear:

  • Severe skin itching in the pubic area, anal opening, hair areas of the body. Sensations intensify at night, during the day some relief comes.
  • Irritation, redness, eczema at the site of parasite bites. The patient is not recommended to comb bites, this can lead to the transfer of infection into the body.
  • The appearance of hematomas. After a lice bite, there is a slight hemorrhage under the skin, which causes the appearance of blue spots with a diameter of not more than 1 cm.
  • The presence of white larvae in the hairline, detected by visual inspection.
  • Allergic reactions.

Diagnosis, symptoms, causes and treatment

It’s not so difficult to diagnose phthyriasis in men: for this enough visual inspection. However, it is necessary to consider: if there is a likelihood that the disease is sexually transmitted, doctors always prescribe additional examinations to identify other possible sexual diseases.

As far as treatment is concerned, curing phthiasis is relatively easy. Currently, there are a large number of ointments, sprays, emulsions, and other effective agents for the treatment of phthiasis. All remedies are safe (with the exception of some that are contraindicated for pregnant women), but it is better to consult with specialists before using them.

If we talk about special shampoos - doctors say that very often people regard them as an effective and independent means of combating phthiasis. Despite this stereotype, shampoos alone are ineffective, and they are recommended to be used as an adjuvant along with ointments.

As with any other disease, the treatment of phthiasis with medical means is steadily accompanied by alternative methods. For some reason, many people believe in the power of "grandmother's" recipes and think that traditional medicine is no less, if not more effective.

A less dangerous and more natural way is to treat the affected skin with cranberry juice.

Today, doctors do not deny the benefit of this method, but it is rather an adjuvant, in addition, cranberry juice can cause local burns and allergic reactions.

Complications and consequences

Can pubic lice be dangerous for a man?

No, as such, this disease is not dangerous. The only thing is that lice on the human body can provoke a strong allergic reaction. Also a danger to the patient is that when combing the skin, a person can cause an infection. In particular, this can be dangerous if the disease is provoked by sexually transmitted infections - gonorrhea, chlamydia, syphilis, ureaplasma.

How can I get phytiasis?

There are several ways to spread the disease. Most susceptible to this are women and men, leading an asocial lifestyle and promiscuous sex life, as well as not observing personal hygiene.

But you can also catch pubic lice through:

  • clothes of a sick person
  • towels and bed linen
  • public toilets
  • beaches, tanning salons,
  • baths, saunas, pools, etc.

Even with careful hygiene, no one is protected from infection, so it is important to be careful when visiting public places and communicating with potential parasite carriers.

How to cure phthiasis

Treatment of pubic lice involves a series of procedures not only in the patient, but also in the sexual partner. The best option is to consult a dermatologist or venereologist. The specialist will not only prescribe competent treatment for pubic lice, but will also conduct an examination to identify other sexually transmitted venereal diseases.

You can get pubic lice at home. It is better to use pharmaceutical preparations for lice. They are available in the form of shampoos, concentrates, sprays, ointments.

Folk methods are not safe. Kerosene, vinegar, hellebore, hydrogen peroxide can greatly damage delicate skin and mucous membranes of the genitals. The only remedy that practitioners of alternative therapy can use without worrying about the consequences is tar soap.

Genital pediculosis is cured by epilation. To do this, you need shaving foam, a razor and an alcohol solution for disinfecting the skin after the procedure. Having removed all the vegetation, at the same time it will be possible to get rid of lice, since they live only on the hair.

Fashion for intimate haircuts threatens the extinction of the appearance of pubic lice.

If for any reason it is not possible to shave off the hair, it is necessary to purchase anti-pedicular drugs in a pharmacy and conduct a course of procedures at home.

Methods of treatment and prevention

Pubic lice is treated with the appearance of the first symptoms of the disease. Untimely use of drugs can provoke a strong allergic reaction and intolerable skin itching. The risk of contracting infectious diseases will increase.

How to get rid of pubic lice? Treatment of pubic lice is carried out at home, using special anti-lice agents and following certain rules:

  • To begin with, all the hair on the pubic area is shaved. Thus, most parasites will disappear on their own and the effectiveness of drugs against lice will increase significantly.
  • The infection site is thoroughly washed and wiped dry. An anti-parasite agent (shampoos, emulsions, gels) is applied to the inguinal region or other affected parts of the body. It is necessary to strictly follow the instructions on the packaging, and keep the product on the skin for exactly as long as indicated by the manufacturer.
  • If the hair does not shave, it is necessary to remove the extinct lice with your hands or using a special comb.
  • To destroy parasites on bedding, clothes, towels and personal hygiene items, wash them in hot water or an alkaline solution. After that, things are ironed carefully, all irregularities and folds are straightened out.
  • Items that can not be washed are placed in a hermetically sealed bag for 2 weeks. During treatment, it is necessary to change bedding and underwear, towels as often as possible.
  • All sexual partners in the last month preceding infection should be warned of pediculosis. Men and women should also begin timely treatment.
  • Compliance with personal hygiene. Regular washing reduces the risk of louse breeding.
  • Until complete recovery, it is necessary to withstand sexual rest. Affection of the partner can be at any time.
  • 9-11 days after the end of the course, therapy is repeated. In this case, it will be possible to remove all newly appeared lice.
  • It is strictly forbidden to crush insects with fingers and nails, to eliminate the risk of developing infectious diseases. In extreme cases, the chemical treatment of the apartment and all items in it.

Personal hygiene is the key to a healthy body

Almost all anti-pediculosis drugs contain permethrin and malathion. Herbal preparations are used at home. Their action is based on the insecticidal effect on parasites. All funds are safe and dispensed in a pharmacy without a prescription. The main side effect of the use of drugs against pediculosis is the possible occurrence of an allergic rash. You should check the effect on other parts of the body before using it on the delicate pubic area.

After using anti-lice products, skin irritation may occur. To eliminate it at home, both pharmaceutical preparations and folk remedies are used: chamomile, solutions of manganese or furatsilina. All these components have a calming effect on the skin.

Regular and thorough personal hygiene, as well as cleanliness in sexual activity are the main preventive measures against pediculosis of the inguinal region. People whose infection with lice can occur most often (workers in public places, in hospitals, prisons) need to take personal precautions: change, wash and iron clothes daily, take a shower regularly, use preventive measures if there is a possibility of infection (tar soap, wormwood tincture).

If the first symptoms of pubic lice are detected, you should not self-medicate, but it is better to consult a doctor immediately. A dermatologist will assess the degree of condition and prescribe a course of drugs that can be used already at home. It will not work to get rid of parasites with ordinary soap or thorough showering. An integrated approach to the problem is needed, both for a man and a woman at the same time.

Treatment of pubic lice is very effective. If all the rules are followed, parasites can be eliminated quickly enough.


Prevention of phthiasis is primarily hygiene measures and minimizing situations in which the disease can be transmitted. Here are the main points for the prevention of phthiasis:

  1. Attentive to personal hygiene.
  2. If possible, use only personal household and clothing items.
  3. This also applies to bedding: it is not recommended to sleep on someone else's or suspicious linen.
  4. Legible attitude to sexual contacts.
  5. Regular replacement, washing and ironing of clothes and bed linen.

Of course, special attention in this list should be given to promiscuous and suspicious sexual contacts, ideally it is better not to allow them at all. But even after seemingly innocuous everyday contacts with unfamiliar or untrustworthy people (for example, after a handshake or hug), it’s worth taking a shower.

A little about lice and phthiasis in general, see the thematic video:

How to diagnose a disease?

To diagnose pubic lice, you need to consult a dermatologist. According to the patient's characteristic complaints, one can determine the type of disease. Upon examination, larvae of lice and nits will be found on the body (in order to identify them, it is not necessary to use laboratory methods, you can use ordinary magnifying glass). In places where lice are affected, it will be possible to detect small particles of a rusty color, you should not be scared - these are the discharge of lice.


Even if you yourself have discovered pubic lice, you should not think that they will be removed using ordinary soap and showering. Damage to pubic lice is a serious disease that must be eliminated with the help of special ointments, as well as sprays aimed at the destruction of parasites. It will definitely be necessary to completely shave off the hair at the sites of lice damage.

Another nuance of pubic pediculosis is that this disease is transmitted sexually, which means that one and the second partner must undergo treatment at the same time.

What causes the disease

The causative agent of parasitic disease is pubic louse. Most often, parasites are located on the hairline in the groin, armpits, eyebrows, scrotum, pubis, in the near-canal zone. There are also cases of phthiriasis on the mustache and chest in men. Selective damage is due to the fact that the louse of Pthirus Pubis, due to the peculiarities of the structure of the legs, can only move along the hairs with a triangular section. Because the section of hair on the head is round, the pubic louse on them does not parasitize. However, occasionally, phthiasis can be located on the scalp in young children.

When propagating, lice bite through human skin, feed on blood, and lay eggs at the roots of hair in areas rich in apocrine glands. Symptoms of the disease and possible complications are caused by a violation of the integrity of the skin, the influence of the waste products of the parasites, as well as the addition of a secondary infection.

Pubic louse, in comparison with other insects of this suborder, reproduces slowly. For a day, the female is able to lay 1-3 pear-shaped eggs with a small lid on the upper pole. The egg can survive outside the host for about 7 days. Adult individuals, having unhooked from the human skin, are able to live without food for no more than 24 hours, however, there are cases of suspended animation of these insects.

The wearer, unlike other types of lice (such as clothes and head), is not able to tolerate dangerous infectious diseases, such as typhoid fever or Volyn fever.

How to remove pubic lice?

Treatment of pubic lice is possible using several methods:

  • Chemical - effects on parasites with special medications. Some disrupt the nervous system, paralyze and kill lice, while others envelop them with an airtight film, leading to suffocation.
  • Folk - the use of home treatment methods.
  • Mechanical - complete shaving of hair with subsequent antiseptic treatment.

The most effective, fastest and easiest way to remove phthyriasis is chemical. However, as a result of its use, the patient may experience a severe allergic reaction and poisoning of the body.

It is necessary to apply it with caution after consulting with your doctor dermatovenerologist.

Effective drugs

Genital pediculosis is not a sentence. And although the elimination process is somewhat different from getting rid of head lice in view of the fact that combing out nits with a comb in the genital area is unlikely to be possible, curing phthiasis can be done in several procedures. How to treat pubic lice:

  • Medifox - is available in the form of concentrates, which must be diluted with water in accordance with the instructions before use. The composition includes permethrin, alcohol, castor oil. Apply via a cotton swab to infected areas. The product is aged for up to 20 minutes, after which it is thoroughly washed off with plenty of water. The medicine does not have an ovicidal effect and does not destroy nits. Therefore, after 7 days, re-processing is carried out.
  • Nittifor - a solution, ready for application. It is applied similarly to the previous tool.
  • Pedilin - an effective remedy for pubic lice and nits based on permethrin. The active substance blocks the insect's nervous system, which causes its paralysis and subsequent death. Shampoo is applied to wet hair, after 10 minutes it is washed off with warm water. Repeat the procedure no earlier than a week later.
  • Veda - shampoo for pubic lice. The drug does not require dilution and is applied to moisturized hair. The exposure is maintained for 10 minutes, after which the product and dead insects should be washed off with water.
  • Nyx is a German ointment for pubic lice with permethrin content. The cream is evenly distributed on the moistened hairline. For ease of application, you can use a special spatula, which is usually attached to creams for hair removal. After 10 minutes, the drug and the euthanized individuals should be removed.
  • Paranit - a spray from pubic lice based on dimethicone. When applied, silicone compounds envelop the parasites with a thin film, which leads to their strangulation and death. The aerosol is sprayed onto dry hair and washed off after 20-30 minutes. Similarly, the Nyuda remedy works.

In order to get rid of pubic lice, in addition to carrying out hygiene procedures, daily change of underwear, bedding, towels, and sanitization of the apartment should be carried out. Things must be treated with disinfectant solutions, washed at the highest possible temperatures and ironed with a hot iron.

How to treat?

How to treat pubic lice?

  • Report the disease to your sexual partner to begin concurrent treatment.
  • Observe hygiene rules (shave off hair at lice parasitic sites and take a shower several times a day).
  • Completely change bedding and underwear, as well as towels. Thoroughly wash the clothes that you usually wear and iron them.
  • During the disease with pubic lice, you often need to change bedding and underwear.
  • For pediculosis treatment use: Medifox emulsion, Nittifor solution, Veda-2 shampoo, Pedillin emulsion and shampoo, special Vitar soap. Use drugs only in accordance with the instructions.

The only possible prevention of pubic lice is compliance with personal hygiene rules, legibility in sexual contacts, and when forced to stop at hotels of questionable service, try to sleep on your underwear.

Appearance and features of the development of the parasite

Adult insects have a grayish or light brown color and a microscopic size of 1-2 mm. In this case, females are larger than males and, accordingly, feed on large volumes of blood. The scavenger has a flat head and 3 pairs of massive paws, due to which it seems that the width of the parasite is greater than its length. The paws have an end like a claw, due to which the ectoparasite is attached at the very root of the hairs.

Parasite Life Cycle:

  • When a healthy person enters the body, lice (adults) begin to multiply actively. The female is able to lay 2-3 eggs per day. Nits reach a size of 0.6-0.7 mm, have a pale color, which makes them almost invisible. They are attached at a distance of 1.5-3 cm from the root of the hair.
  • After a week, the first molt of larvae occurs. The second molt occurs on day 10 of the male and on day 12 of the female of the future louse. The last time the larvae molt on days 13 and 17, respectively. Young larvae do not move around the body of the host, they are motionless and feed on blood, having immersed their proboscis in the skin of a person.
  • 2 days after the third molt, the female acquires the ability to lay eggs. Under favorable conditions, the louse can be on the body for about 20 days and lay about 50 eggs.

The plate feeds once every 4-5 hours, drinking about 0.5 ml of blood for each intake. Without access to the human body, the insect dies within 1-2 days.

Dilators are inactive. In contact with bedding, a towel and clothes, they can crawl onto a person only in close contact with the inseminated item. These parasites are unable to move in search of a host for long distances.

Insects have low resistance to changing environmental conditions. The optimum temperature for their existence is 30-32 degrees, when heated above 40 degrees, the development of larvae and the reproduction of adult individuals stops. At a temperature of 55 degrees or freezing to -5, parasites die within 30 minutes.

For a comfortable existence, women need moist and warm air. In the dried state, they lose their mobility and ability to attach, therefore, showered with hair. This is used by medical workers in many clinics. The primary treatment of the patient consists in treating the affected areas with a stream of air from a hair dryer (at a temperature of 50 ° C), followed by combing the hair with a special comb.

What is dangerous phthyroidism

Damaged by combing the skin - favorable conditions for infection in the body. Combed areas become infected, ulcers, boils appear on them. If untreated, the infection goes deeper - into the lymphatic system. This can lead to systemic diseases, blood poisoning. Pubic lice with their saliva carry infectious diseases, for example, typhoid, from person to person.

Many patients have allergic reactions. Also, almost always phthyriasis is accompanied by sexually transmitted diseases. It can be chlamydia, gonorrhea, syphilis. Pubic lice, passing from person to person, carry the causative agents of these diseases in the saliva. This is the most dangerous infection with pubic pediculosis.

With a very severe defeat of a person and with a large number of lice, they do not have enough space for life in the groin and armpits. In this case, they can live on eyebrows and eyelashes. When these sites are affected, conjunctivitis, blepharitis and other eye diseases develop.

Boric Ointment

An effective remedy for pubic lice - has antiseptic, antiparasitic and antifungal properties. The ointment should be applied to the affected area, and after 20-30 minutes, rinse off the ointment and comb out the parasites with a small comb.

Dosage and number of applications depends on the stage of the disease.

The use of 5% boric ointment to combat pediculosis is possible only after consultation with your doctor, since the drug is contraindicated in children under 1 year old, pregnant and lactating women, people with skin diseases and kidney failure.

How does infection happen?

Infection with a parasitic disease is possible only with close bodily contact. Phytiasis most often occurs after intercourse, during which the louse jumps from the body of a sick person to healthy skin. When infected by sexual contact, harmful insects spread on the pubis, in the perineum and anus.

You can become infected even if personal hygiene rules are not respected - using someone else’s towels, wearing someone else’s clothes, especially underwear. You can get sick with phthyroidism, neglecting the rules of personal hygiene in public places (baths, saunas, swimming pool). A household transmission method causes the occurrence of axillary phthyriasis, eyebrows, beard and mustache in men.

From the site of primary localization, the plaques can spread throughout the patient's body. At the beginning of treatment, they from the genital area will crawl onto the hairline of the hips, chest, eyebrows and eyelashes.

Specialists identified certain categories of the population that are at risk for infection with this disease. These include:

  • persons who do not have a specific place of residence,
  • military or civilians who are in a conflict zone,
  • medical workers, cosmetologists, masseurs, stylists, hairdressers,
  • workers in baths and saunas,
  • dry cleaners
  • kindergarten and boarding school teachers,
  • persons serving sentences in the MLS,
  • sex workers.

Ftiriasis is not transmitted from pets, animals and birds. Infection occurs only from a sick person or from a carrier of pubic lice. With intimate pediculosis, the incubation period is 20-30 days.

In recent years, phthiasis is less common. Experts attribute this to a fashion for shaving or hair removal in the bikini area.

To protect against infection with pubic lice, it is necessary to carefully observe the rules of personal hygiene and safety measures in public places.

Ways to deal with pubic lice

It is much easier to get rid of pubic lice than from head or clothes. The most effective way is mechanical. That is, you just need to remove all the hair from the affected area completely, so that the parasites do not have the opportunity to live on the body. On smooth skin, they cannot move. Received in the last few years, the "fashion" for hair removal in intimate areas has significantly reduced the incidence of this disease.

If you are affected by pubic lice, you need to shave or otherwise remove the hair on the infected area. It is better to remove hair throughout the body so as not to leave the opportunity for parasites to survive the adverse conditions nearby. After hair removal, it is advisable to apply a pediculicide to the affected area to destroy nits, which, due to their small size, can hide in skin flakes.

If for some reason it is impossible to use the mechanical method, then folk remedies or special drugs that kill lice and nits can be used.


An external remedy for pubic lice and nits - has insecticidal and antiparasitic properties. Nittifor is available in the form of a cream and a ready-to-use aqueous-alcoholic solution.

It is rubbed into the affected areas, after which after a while the dead surfaces and nits are combed out with a fine comb. The cream is not recommended for children under 5 years of age, during pregnancy, the presence of allergic reactions and acute inflammatory skin lesions.

A water-alcohol solution of Nittifor is applied to the affected skin, kept for 40 minutes and washed off with warm water. It is recommended to carry out 2 treatments with an interval of 5-7 days.

Traditional methods for diagnosing pubic pediculosis

Diagnosis is often carried out by combing the hair with a thin scallop with frequent teeth, during which live lice or nits that the doctor sees with the naked eye, or with a magnifier, are revealed.

If suspicious parasites are found, in order to fully make sure that it is a pubic louse, an insect or nits are examined under a microscope.

Unfortunately, such a thorough examination of the doctor often causes resistance from the patient, which in every way impedes the procedure. Difficult to diagnose and the location of parasites in hard to reach places - skin folds, bundles of long, tangled and curly hair that are not cut by the patient. In this case, the doctor may not notice a small pubic louse due to the fact that it is in a secluded place, or the doctor has not too sharp eyesight.

Clinical manifestations

The main symptoms of phthiasis include:

  • Itching sensation at the location of the parasite and nits (pubis, perineum, area around the anus, armpits, mustache, chest and abdomen in men). This symptom is caused by skin damage caused by a lice bite and insect saliva entering the human body. The intensity of itching depends on the individual sensitivity of the patient's body to the products of the vital activity of the parasite.
  • Small maculopapular eruptions on the skin of the affected areas. The appearance of bluish spots on the skin is associated with the destruction of hemoglobin under the influence of lice saliva.
  • Occurrence of blisters, reddish tubercles in the area of ​​pubic lice settlement.
  • Skin thickening in the centers exposed to rash. The skin becomes rough, rough, wrinkles appear more clearly on them.
  • Numerous combs, crusts and dandruff are formed as a result of skin damage during intense scratching.
  • Excursions - deep damage to the skin. Very dangerous by the addition of a secondary bacterial infection.
  • Brown spots irregularly shaped on the skin and clothes - the vital products of the ploshchita.

With the localization of the parasite in the area of ​​the eyebrows and eyelashes blepharitis may occur.

It is difficult for a person to detect parasites in himself during self-examination. Therefore, often the presence of these symptoms, people are mistakenly associated with manifestations of allergies to detergents, with a violation of personal hygiene rules, they are mistaken for symptoms of other sexually transmitted diseases.

If the slightest signs indicating pubic lice appear, you should immediately consult a dermatologist to clarify the diagnosis and prescribe the correct treatment.

Folk remedies

These are the same tools that are used to destroy hair or body lice and nits. The affected areas are lubricated with such means:

  • vinegar solution
  • pulp from crushed cranberries,
  • Castor oil,
  • geranium oil.

All of these options are quite gentle. They do not harm health, but for the onset of effect require long-term use. With severe damage to the pubic lice, they are powerless. In addition, you will have to leave the remedy in the affected areas for some time for exposure. This is not always convenient and appropriate.

You can use more aggressive options:

  • 3% hydrogen peroxide,
  • boric or sulfuric ointment,
  • kerosene.

You need to use them with great care, as these agents may prove toxic or cause burns to the mucous membrane. In addition, they may be ineffective against nits.


Available in the form of a cream (gel) for hair and 5% concentrate for the preparation of emulsions.The active substance is permethrin, which actively fights pubic lice and nits.

A 0.2% aqueous emulsion (dilute 4 ml of a 5% solution in 100 ml of water) is prepared immediately before use and applied liberally to the hairy parts of the body, and then after 20 minutes it is washed off with running warm water using soap or shampoo.

The product is not recommended for children under 1 year of age, lactating women and persons sensitive to permethrin.

Modern approaches to the diagnosis of pubic lice

A more accurate and less time-consuming method of detecting pubic lice is to illuminate a Wood lamp, in the light of which the live nits of the parasite fluoresce white as a pearl. Empty, dead nits in the light of Wood's lamp look like gray shells. It should be remembered that the pubic louse can settle on the eyebrows and eyelashes, which can also be examined using a Wood lamp or a slit lamp of an ophthalmologist.

Today, an accurate method for diagnosing pubic pediculosis, video dermatoscopy, has been developed and put into practice by doctors in developed countries. For this, a digital videoscopy system is required, consisting of a specialized video camera, which has the function of light polarization and video capture. The camcorder connects to a computer on which the appropriate software is installed. As a result, the doctor can remove a certain area, the image of which is copied to the computer in the form of photographs enlarged 80 times (separate files). After that, the doctor can examine in detail each suspicious area of ​​the patient's body, and make sure the presence or absence of pubic lice and nits. The method avoids the conflict between the doctor and the patient who does not want to recognize the presence of parasitosis, since the doctor can demonstrate a photograph of an enlarged pubic lice or nits.

In addition, undeniable evidence of pubic lice, as a rule, forces a person to more carefully follow the doctor’s instructions for the treatment of pathology. Video dermatoscopy can also be used to control the cure for pubic lice, since an enlarged picture allows you to clearly visualize dead nits from live nits according to a number of signs: non-viable ones do not have a lid, and do not contain eggs inside the shell. Such a high diagnostic accuracy allows you to accurately determine the need for treatment, since dead nits do not require therapy - you only need some time to wash them off your hair. Unfortunately, after a course of treatment, itching and scratching continue to bother people for some more time, which they take for incurability. Video dermatoscopy allows you to clearly determine if there are still live parasites, and whether additional treatment is required.

Also, video dermatoscopy can detect pubic lice in the presence of a large amount of dandruff.

Professional Tools

Ftyriasis should be treated with medication using effective agents that work against lice and nits. These are pediculicides that kill parasites. You can use drugs based on different active ingredients: Medilis-Permifen, Medilis-Bio, Medilis-Malathion or Medilis-Super. They are available in the form of a spray or emulsion. Each drug is accompanied by instructions for use, which must be strictly adhered to. Most drugs can be used by people who are not individually intolerant. Some can be used to treat children from 5 years old. The result will come in a few minutes or hours.

Other means

In addition to the above drugs, you can use:

  • Pediculen Ultra Lotion - when combating pubic lice, the lotion is applied to the affected areas for 20-30 minutes, then washed off with water. After that, comb out the lice and nits with a small comb. After a week, the procedure is repeated.
  • Shampoo and emulsion Pedilin - It is produced to combat head lice, but it also effectively fights pubic lice. It is applied with a cotton swab and washed off after 25-35 minutes. If necessary, the procedure is repeated after two weeks.
  • Medilis super - the drug is harmful to lice and nits. The mixture is applied for 20-30 minutes, and then washed off with soap. Dead lice and nits are combed out with a small comb.

Principles of treatment and agents used to treat pubic lice

The following measures are the basis for effective treatment and prevention of the spread of pubic lice:
1. Two stages of therapy, which are necessary in connection with the features of the vital activity of pubic lice.
2. Mandatory prophylactic treatment of all people who had close contact with the patient.
3. Disinfection of patient items.

For the treatment of pubic pediculosis, special chemotherapeutic substances are currently used - pediculocytes, which are insecticides that selectively act on lice and nits. Pediculocytes do an excellent job of eliminating pubic lice and nits, but at least two treatments should be carried out, since the destruction of the next, nascent generation of the insect is necessary.

Before the appearance of pediculocytes, a variety of compounds were used as insecticides against pubic lice, which treated the affected surfaces. So, the following compounds were widely used to combat pubic lice:

  • soap and kerosene mixture,
  • Sulfuric ointment,
  • tar ointment,
  • benzyl benzoates.

Today, the most effective pediculocytes are drugs that include pyrethrins as active substances, or the drug Lindane. Pyrethrins include malathion, carbaryl and permethrin. Moreover, permethrin showed the highest efficiency in the treatment of pubic lice.

What you need to do in the treatment of phthiasis

Pubic lice can hide not only on the human body, but also in his personal belongings. Therefore, it is important to treat underwear, clothes, bedding, and towels during treatment. All things that can be washed should be soaked in a pediculicide solution and washed at high temperature, and after drying thoroughly ironed or treated with a steam generator. Cabinets where clothes and underwear are stored should be washed with a pediculicide solution. Mattresses and upholstered furniture are preferably treated with a steam cleaner. Since lice can wait out unfavorable times in a state of suspended animation, it is necessary to do a general cleaning, wash all surfaces with an insecticide solution. This will remove insects from the home that could survive the treatment and then return to the human body.

Alternative methods of treatment

Treatment of pubic lice at home should begin with complete removal of hair in the affected area. Since lice are attached to the bases of the hair, shaving does not guarantee complete elimination of parasites.

Consider the most common methods:

  • Using apple cider vinegar treatment is carried out within three days. Vinegar is diluted in 3% concentration and applied to the affected area for 30-60 minutes, then washed off. With this method, you can not shave the hair. Under the influence of acetic acid, lice and nits detach from the hair and die.
  • Birch tar - the course of treatment is 9-10 days. 1 tbsp. a spoonful of butter is mixed with 1 tbsp. fly in the ointment. The resulting mixture to treat the affected areas.
  • Hellebore waterpossessing antiparasitic properties - before use, wash and dry the infected areas, gently apply helical water to the scalp, rinse after 10-15 minutes. It does not kill nits, but significantly weakens their connection with hair. Therefore, at the end of the procedure, the nits should be combed out with a special comb from lice. In advanced cases, after 1-1.5 weeks, the procedure can be repeated. When working with chemerichnoy water should be careful. It is contraindicated in pregnant and lactating women, children under 12 years old.
  • With kerosene lice can be removed in one day. A mixture of 1 part kerosene and 10 parts of sunflower oil is prepared. Gauze impregnated with this mixture is applied to the affected area, covered with a cellophane film and fixed with a plaster. After three hours, the gauze is removed, the treated area is thoroughly washed and treated with a greasy cream or oil. The method of treatment with kerosene should not be used during pregnancy, lactation, children of school age and skin irritation. It should be used with great care, since kerosene is able to burn the mucous surfaces of the genital organs and skin.

Treating pubic lice on your own at home is not quite the right decision because not all alternative methods are effective and useful for the patient.

Pubic louse is often only a concomitant disease with other more dangerous sexually transmitted problems (syphilis, gonorrhea, chlamydia, ureaplasmosis). Only a competent doctor dermatovenerologist can cope with them.


The main modern drugs for combating pubic lice, presented on the domestic pharmaceutical market, are shown in the table:

Insecticide groupActive substanceRelease formCommercial name
Organic phosphatesMalathionEmulsion gelPedilin
PyrethrinsPyrethrinSpray canSpray pack
FenotrinLiquid soapAnti bit

If the dosage form contains only one active substance, then there is a need to re-treat the infected surfaces 7-10 days after the initial disinfestation. Such drugs are called monocomponent, and the following agents are referred to them:
  • Pedilin
  • Nittifor,
  • Knicks
  • Medifox,
  • Anti-bit.

A simpler to use and effective dosage form against pubic lice is characterized by a combination of the active substance and a substance that prolongs the action of the main component. Such drugs are combined and include Spray-Pax aerosol, which is produced by the French pharmaceutical company Pharmygiene-SCAT. When using combined preparations against pubic lice, a single treatment is sufficient.


You need to start specialized treatment for pubic lice immediately after the doctor-dermatovenerologist sets the correct diagnosis. The complex therapy of phthiasis includes such means as:

  • Emulsion Medifox 5%. It must be dissolved in warm water (the amount is indicated in the instructions) and applied to the hair. After a 20-minute exposure to the drug, you must take a shower.
  • Nittifor solution - in undiluted form is rubbed into the skin of the affected area. The exposure time of the drug is 40 minutes, the procedure must be repeated a week after the first application.
  • Soap Vitar - they should treat areas of the body affected by pubic lice, rinse with warm running water after 2-3 minutes. Experts recommend repeating the procedure after a week.
  • Pedilin is an anti-pediculant, produced in the form of shampoo. The drug should be applied to the affected area with a cotton pad, rubbing intensively into the roots and rinse off after half an hour. Repeated application of the drug must be repeated after 14 days.
  • As additional drugs (in the presence of allergic symptoms), antihistamines are used - Loratadin, Suprastin.
  • If pustular complications are identified, antibiotics of the penicillin and cephalosporin series are prescribed, as well as treatment of the affected areas with solutions of local antiseptics.

Means for the treatment of phthiasis should contain aggressive insecticidal components, such as cypermethrin or deltamethrin. During the first treatment, adult insects die, with secondary exposure (after a week), the larvae hatching from the surviving eggs are destroyed.

With severe complications of phthyroidism, such as Quincke's edema, anaphylactic shock or sepsis, treatment of the patient should be carried out in a specialized hospital.

When diagnosed with phthyroidism, the patient needs to shave their hair in the genital area and around the anus, in the armpits and, in rare cases, on the chest or head. It is not recommended to remove hair in other ways (wax depilation, shugaring), since these manipulations lead to additional damage to the skin.

Treatment for phthiasis should also be carried out with the sexual partner of a sick person. Much attention is paid to the prevention of the spread of the disease in domestic conditions, in order to prevent infection of people living in the same territory with the patient.

On the video, doctors talk in detail about methods of infection with phthyroidism, symptoms and treatment of the disease.

Preventive actions

These simple recommendations will help protect against sexual lice:

  • Observe personal hygiene
  • Exclude promiscuous sex,
  • Do not wear other people's clothes, do not try on underwear in stores,
  • Change and iron underwear more often,
  • Do not sleep on dirty linens on trains and cheap hotels,
  • Be vigilant when visiting public places - baths, tanning salons, swimming pools and gyms.

Aerosol for the treatment of pubic lice

Spray pax is used to treat pubic lice. Aerosol is sprayed with short presses on the dispenser to the pubic hairline. Processing is considered complete when the aerosol completely covers the skin and hair of the pubic part. The drug is left on the surface for half an hour, after which they thoroughly wash the body with warm water and soap. Proper single treatment of infected areas with aerosol can completely cure parasitosis.

Aerosol Spey-pax should not be used during pregnancy and lactation, as well as in the presence of strong scratches on the surface of the skin. To prevent re-infection, it is necessary to spray the pubic area of ​​people who are in close contact with the patient with an aerosol Spray-Pax.

What do pubic lice look like?

Pubic lice have an inconspicuous yellow-gray color. They resemble small crabs up to 2-3 millimeters in size. Pubic lice live about 25-30 days and feed on human blood. One individual lays about 50 eggs.

The accumulation of nits of pubic lice externally can resemble a large amount of dandruff, especially on the scalp in men.

Disinfection of personal items

To disinfect the personal belongings of a patient suffering from pubic lice, special substances are used - disinfectants. A-vapor aerosol has excellent effectiveness as a disinfectant. In the treatment of pubic lice, in parallel with the treatment of the pubic zone with Spray-Pax, it is necessary to disinfect A-pairs with all patient’s underwear, both bed and underwear, including T-shirts and underpants that are worn as a boot in the cold season. Aerosol A-steam does not affect the purity of things and does not change the properties of tissues. After processing things, they do not need to be cleaned.

If a person does not have the opportunity to perform disinsection using a specialized tool, then it is necessary to boil all the linen, since pubic lice and nits can not withstand the high temperatures at which they instantly die.

The consequences of pubic lice

Lice do not pose a danger to humans, but due to constant combing, the integrity of the skin is impaired. If untreated, the lesions can develop into eczema, which in turn can cause secondary sexually transmitted infections, boils, and abscesses.

When pubic lice are settled on the eyelashes, inflammation of the edges of the eyelids (blepharitis) and inflammation of the mucous membrane of the eyes (conjunctivitis) can form.

Only timely diagnosis and individual treatment by a dermatovenerologist, taking into account the characteristics of each patient, will help to cope with this disease and possible consequences.
