    Head lice prefer to settle on the scalp in the neck and temples. A semi-transparent grayish insect feeds on human blood. Life expectancy of the female is a little over a month. Every day she can lay about ten eggs, which she attaches near the roots of her hair with a special sticky secret. Grayish-white nits will turn into larvae after a week, after two they will become adults and the cycle will repeat.

    The oral apparatus of this parasite is designed in such a way that it is easy to bite the human skin. At the time of the bite, saliva of lice is released into the wound, which has irritating abilities and leads to the appearance of severe itching.

    The person starts combing the injury site, thereby increasing the risk of infection. At the place of the disturbed bite, the skin turns red, seals and crusts appear. Infection can spread to nearby lymph nodes.

    Louse lice eat on the victim's body, but live and lay nits in the seams and folds of a person's clothing. Parasites are found around the neck, between the shoulder blades, in the knee and elbow folds and at the waist. After themselves, they leave itching and rashes, similar to hives.

    If this form of the disease does not find proper treatment, skin inflammation and complicated dermatological diseases appear. The skin becomes thicker, its shade changes to gray-brown, combed bites are covered with white scars.

    Pubic lice( raincoats) choose the areas of the pubis and anus for the habitat. The method of transmission of this parasite is predominantly sexual, although infection through everyday objects is not excluded. With a fairly dense hair cover on other parts of the body( abdomen, eyebrows, beard, underarm zone), the probability of spreading pubic lice increases.

    In addition to bites and unpleasant itching, pubic lice leave small spots of bluish-gray color on the human body, in the middle of which the point of bite is visible. Markings disappear within one or two weeks.
