Why there are nits, but no lice

Pediculosis continues to exhaust people, despite the huge amount pharmacy drugs, folk remedies. The most vulnerable are children, adolescents. Of particular indignation in adults is the situation when eggs are found on the hair of a child, there are no adults. Could there be nits without lice, or should I look better?

Features of head lice

The causative agent of the disease is a small insect - louse. Body length not more than 4 mm. Parasites are transmitted from a sick person with close contact, through hats, combs.

• TO breeding process adults begin immediately after the last stage of the nymphs. One copulation is enough to fertilize all the eggs of the female. Lice lays about 4 eggs daily. Life span adult from 30 to 40 days.
• Nits are attached to the hair with sticky, sticky substances. Upon contact with air, it hardens, providing a firm hold. Nits cannot be washed off with shampoo, combed out with an ordinary comb. This is the main difference of dandruff from nits.
• The location of the eggs on the hair can determine the approximate time of infection. The louse does the very first masonry at a distance of 1 cm from the roots. As the hair grows, they appear on any part of the head.
• In the egg, the larva develops from 7 to 14 days. A creature similar to adult lice appears, but differs in small sizes - up to 1 mm. For a week, nymphs go through 3 molts. They turn into a mature louse.

The incubation period of pediculosis It lasts until the birth of the first offspring - about 14 days. Nymphs begin to eat actively, appear lice bites on the scalp, severe itching.

Interesting!

Not a single folk remedy, a pharmaceutical drug, pediculicidal shampoo not able to destroy the shell of lice eggs. Larvae continue to develop actively. The only effective method is combing with a special comb.

where they do not disappear even after the publication of larvae. Eggs are not able to cross on the head of a healthy person. Therefore, the question often arises - why are there nits, but no lice?

Causes of unusual situations

Prevention, identification of lice are carried out by medical workers of educational institutions, parents. Scratches on the head, scratches, abrasions, do not give reason to accurately diagnose the disease. It is necessary to detect lice or nits. The situation is puzzling when only parasite eggs are visible on the hair, they themselves are not.

On a note!

Pediculosis is an insidious disease that is not so easy to detect when a quick examination of the head. Nits can easily be confused with dandruff, lice simply do not notice. There should be good lighting, a magnifying glass or a magnifier, a shallow comb.

• Lice have the ability to adapt to the tone of the hair. Parasites are almost invisible on fair, red hair. To find adults, you need to use a shallow comb. Comb out each strand thoroughly. The situation may mean that lice are simply not noticed.
• Before the appearance of the first offspring, it is enough to eliminate the adult individual, comb out the eggs. If lice accidentally gets under the nail when scratching the head, on the comb, it leaves the head. The spread of lice ceases. A thorough examination of the head reveals only nits.
• A situation may arise when, with close contact with the heads of the louse, it crawls to a healthy person, lays several eggs, and returns to its former habitat.Infection has occurred, live individuals will appear only after 10-14 days.
• Louse hiding in the hairmoves with tenacious paws. It may happen to be on a pillow, clothes, headgear. For unhappy for her, and happy for man circumstances, she finds herself in a life-threatening situation. After 3 days of starvation, dies. Only eggs are found on the patient’s head.
• One of the situations makes you really break your head. Only detected empty nitsThere are no live parasites. This means that the fight against lice was carried out intentionally or accidentally. All living individuals died, the eggs were not combed out. The situation often arises if the hair was dyed. Because the hydrogen peroxide treatment kills lice, corrodes the sticky substance of nits.
• Fight lice can be taken externally or taken orally. The insect drinks blood, receives a dose of a substance harmful to itself, dies. This effect is caused by the use of certain medications, the secondary effect of which the person does not even guess. The same effects have berries, fruits, vegetables. You just need to remember what got into the body over the next month.

There is nothing mysterious about the presence of nits on the head without lice. The situation is logically understandable. Did not notice during examination, an adult individual left her head by chance, events were held to get rid of lice. Always means that the adult in the hair was originally. Larvae cannot exist without adults for physiological reasons.
