What lice bites look like: head, pubic and underwear. Can lice bite the body? What do their bites look like? Bites on a child's neck

Lice live on the surface of the scalp, their eggs are laid by attaching to the base of hair Therefore, their bites are aimed only at feeding. About how long it takes for eggs to turn into adult lice.

Lice begin to bite from the first day of infection, since they need to feed constantly.

What happens during a bite?

How do lice bite? The oral organs of lice are stiletto-shaped jaws that surround the salivary canal and the oral cavity itself.

When a louse bites, it pierces the skin with its jaws, injecting a certain amount of saliva into the wound, which prevents blood clotting - this is what saliva and the enzymes it contains cause irritation, redness and itching around the bite site.

Having bitten through the skin, the louse reaches the nearest vessel and begins to suck blood from it, while trying to press its head as close as possible to the surface of the skin and lifting the back of the body.

An adult louse feeds this way every 2-3 hours.

Where to look for affected areas

We looked at photos of lice bites on a person, now we’ll tell you how and where to find them.

Initially on the skin small bright red papules appear- itchy acute dermatitis.

This happens suppuration of papules, formation of boils, appearance of excoriations (scratching) on ​​the scalp, skin thickening or crusting may occur.

Linen lice attacks can only affect those people who rarely change their underwear, clothes, their bedding, towels, etc. If in the case of head lice, unsanitary conditions play an important role and infection occurs even in clean people due to contact with a carrier, then with clothing (linen) lice, the likelihood of occurrence in sloppy people is recorded most of all. After each treatment of clothing and other things affected by insects, the patient himself should also be treated, and all bites should be cured.

Recognize bites on the body

To be sure that a person has been bitten by body lice, you should simply look at the location of these red dots on the body. Since these bloodsuckers do not jump or fly, but crawl, traces in the form of a path will remain on the bitten areas. If fleas, for example, leave bites scattered throughout the body, then lice will leave chains of such bites.

Most often, relapses occur precisely where clothing comes into contact with the body, inside of which (or on the reverse side) lice live. As a rule, these are places of seam and other folds, internal seams of pockets, hems, collars, cuffs and other areas. This is especially true for clothes made of linen, cotton and wool. Also, such inhabitants like to live in other things made of fur or knitted fabric.

What symptoms do such lesions show?

The patient's internal health problems begin after about a few days (3-4 days). Symptoms are expressed in the following manifestations:

1. The temperature rises.
2. Headache.
3. Allergies may begin.
4. Disorder of the gastrodigestive system.
5. Externally, not only red, but also blue spots of a nature that spread over the skin can form on the body.
6. A rash with pustular formations may appear with severe damage.
7. The person is extremely irritable, to the point of developing nervous disorders.

Concomitant diseases that can begin due to infection with linen lice are the following standard list:

• scabies;
• plague;
• typhus, relapsing fever;
• allergy;
• sepsis;
• viruses and infections of all kinds.

If you only save the patient from such torment in time, then there is a chance that he will not become infected with severe infections or viruses from lice. That is why, when such manifestations are first detected, it is necessary to immediately begin processing things and the body.

Typically, doctors for the treatment of body lice prescribe products that are made with pyrethroids. This could be Medifox or Nitifor. The stages of treating the patient and his further treatment consist of the following measures:

1. First, remove all affected clothing and place it in washing machine together with any pediculent product. Washing is done at a temperature of 60-80 degrees Celsius.
2. The patient takes a shower. The water must be hot - so that it is as tolerable for a person.
3. The infected person washes with a special product, which must be left on the entire body for 30 minutes.
4. Afterwards everything is washed away hot water in the shower.
5. Then the person is dried with a towel; all wounds should first be treated with hydrogen peroxide to disinfect.
6. After 15 minutes of peroxide action, the wounds are lubricated with hydrocortisone or other ointment that has an antiallergic and wound-healing effect.
7. The bite healing procedure is repeated until complete recovery in accordance with the instructions of the medicinal product.
8. To prevent the patient from scratching the healing areas, they should be lubricated with “Rescuer” after the healing ointment (after it is absorbed). It relieves itching perfectly.

Not everyone is aware of what lice bites in the head area look like and whether pests are capable of biting other areas on the victim’s body. Often the results active work individuals are confused with bites of ticks and mosquitoes.

The louse bites not only in its immediate habitat - on the head, but also in other parts of the body. The question of whether nits bite people began to be asked because they were found in patients large quantity dry membranes on the scalp.

The answer to the question posed is negative.

Nits are the eggs of individuals, i.e., underdeveloped lice, which are at this stage are not capable of harming the owner.

How they bite

To begin with, it makes sense to understand how lice bite people. Once in in the right place, the insect begins to use sharp stilettos around its mouth. The flea also has the same “attributes”. With the help of these elements, the pest moves deeper into the skin until it reaches the artery.

Attention! The larvae are also capable of biting. However, their activity is not so dangerous for humans: the amount of irritating enzyme in the saliva of individuals is extremely small.

What do lice bites look like?

A reliable sign of active activity of individuals is the detection of lice bites on the head and body of a person. The skin in the local area turns red, a protracted center is visualized, and itching and swelling of the tissues are noted.

When linen lice bite, pimples 2-4 mm in diameter appear on the human body (not the hair part). Most often, such “marks” are found on the patient’s abdomen, shoulders and buttocks. With increased sensitivity of the body, an allergic reaction manifests itself in the form of extensive swelling and redness.

Areas affected by head lice become crusty when scratched. In this case, pimples appear in no particular order - the points are located chaotically.

Differences between lice bites and other insect bites

This feature of pests is explained by the specific structure of the body - only lice can boast of special hook-shaped growths on their paws, which facilitate the process of moving individuals along the hair.

Bites body lice it is not so easy to distinguish: their marks are approximately the same size, they are located in the area of ​​the buttocks, abdomen, arms, etc.

The peculiarity of lice bites of this type can only be considered their chaotic arrangement.

If you compare a louse with a bug, the latter leaves behind a chain of red dots on the victim’s body.

Why are bites dangerous?

A lice bite is dangerous due to the possibility of infecting the owner with a serious illness.

Diseases carried by insects include:

• relapsing fever. Manifested by fever, allergic rashes, severe intoxication, jaundice of the skin;
• typhus. Accompanied by destructive changes in blood vessels;

1. Wash the affected area with soapy water.
2. Use a disinfectant and dry the affected area (you can use any alcohol-containing composition).
