Our Department's Responsibility Other Sources of Information Identification Head lice are found on scalp hairs, especially on the back of the neck and around the ears.
Nits are often the first sign of a head lice infestation.
Head lice are transmitted by close personal contact with an infected person, or by sharing clothing and personal items such as hats, combs, and brushes. Lice cannot jump from person to person, and pets do not get head lice. There are many steps you must take in treating head lice and it is important to do everything very thoroughly. First thoroughly shampoo the hair with a shampoo that contains no conditioners or softeners. Hair must be very clean so the insecticide will penetrate.
