How to detect body lice. Clothes lice. Body lice bites are accompanied by

One of the two forms of human lice is the body louse, which feeds exclusively on the blood of its owner, but lives in the folds of clothing.

In short, body louse (linen, clothing or bed) louse lives in clothes. Compared to its older “brothers”, it received many more advantages:

increased feeding area - bites occur not only on the head, but on the entire human body;
comfortable living conditions - clothes are warmer and safer than on your head and there is less risk of getting caught.

Externally, body lice are similar to head lice. Body length adult 4 mm, the abdomen is elongated, the color of a hungry insect is gray, a well-fed one is reddish-bluish.

The difference lies in the structure of the legs - they are shorter, which is determined by the habitat. Short legs also reduce the speed of movement - a maximum of 20 cm per minute, while head louse moves 2 times faster.

Photos of body lice are widely distributed on the Internet, so they can be identified quite easily. The entire life cycle takes place in clothing - this is where the insect lives and lays eggs - nits. When hunger strikes, it moves to the human skin, and after satiation it immediately returns back. This is why they are called body lice, linen lice and clothing lice.

The classic incubation period of body louse is usually calculated based on the moment of clutch formation until the hatching of nymphs and the development of full-fledged individuals.

Body lice eggs - nits - are attached to the threads with a special secretion. It is almost impossible to tear them off; you only have to destroy them by heat treatment. Visually, they resemble grains of rice up to 0.5 mm long. It is extremely difficult to notice them even on dark clothes.

How quickly do body lice reproduce?

The first bites appear on the body within a few hours after infection. This indicates the instant adaptation of the insect, and also that they cannot for a long time starve. It is believed that the maximum period of absence of food does not exceed a week, after which the insect dies.

Diagnosis of lice is complicated by the fact that even if you know for sure about the presence of body lice, it is almost impossible to find them. But after a month the consequences become noticeable. This time is enough for the first generation of nymphs to grow up and begin to actively attack the warm-blooded host.

You can notice the presence of body lice after 1.5-2 months - the second generation appears, growing up in good conditions. Here the symptoms become more obvious and anti-pediculosis treatment can be carried out with confidence.

What is body lice

It is possible to diagnose body lice by detecting insects only when their number numbers hundreds or even thousands of individuals. This stage takes on average up to six months from the moment of infection and develops rapidly if treatment is not started in time.

Only that stage of louse development that immediately follows the egg is called a larva. The larva after the first molt is called a nymph.

Body lice eggs are called nits. They are attached to clothing with a special secret, and it is mechanically very difficult to tear them off from it. Each such egg has a slightly elongated shape and a length of about 0.5 mm. Typically, body lice nits can be quite difficult to visually detect on clothing.

As noted above, head and body lice are different shapes of the same type. Under natural conditions, even on the body of one person, they usually do not meet each other (after all, they are separated purely territorially), but under experimental conditions they interbreed and produce viable offspring. Moreover, the offspring themselves have more signs of head lice as the main form.

Lice avoid shiny, silk and satin clothes; they love wool and cotton fabrics.

homeless sleeping areas

refugee camps, shelters during natural disasters

trenches and tents during military operations

kindergartens and schools

public transport

saunas and public baths

on hiking trips

children's holiday camps

dirty cheap hotels.

On a note

Body lice can survive in water for 2 days, and therefore they can, in exceptional cases, be transmitted through water, even in open water. Such cases have been reported in India and Bangladesh.

In addition, body lice bites have a pronounced puncture point in the center of the inflamed area.

Body lice bites are characterized primarily by severe itching, which occurs due to the fact that when an insect punctures the skin, it injects an anesthetic substance into the wound that helps stop blood clotting. Often the human body reacts to this enzyme with an allergic reaction, manifested in the form of acute urticaria. Burning and discomfort force the victim to comb the affected areas of the skin, which inevitably leads to excoriation, that is, its damage. Open wounds become a path for the penetration of bacteria, causing the appearance of pustular formations - the so-called phenomenon of pyoderma.

If you ignore the process for a long time and neglect it too much, unwanted complications may appear in the form of boils and even abscesses, indicating that the infection has gone deep inside.
