The head louse is a parasitic insect that can be found on the head, eyebrows, and eyelashes of people. They are disease free pests. Head lice feed on human blood several times a day and live close to the human scalp. Head lice are not known to spread disease. Head lice are found worldwide. In the United States, infestation with head lice is most common among pre-school children attending child care, elementary schoolchildren, and the household members of infested children. Head lice move by crawling; they cannot hop or fly. Head lice are spread by direct contact with the hair of an infested person. Anyone who comes in head-to-head contact with someone who already has head lice is at greatest risk. Spread by contact with clothing (such as hats, scarves, coats) or other personal items (such as combs, brushes, or towels) used by an infested person is uncommon. Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice. Signs and symptoms of head lice include: tickling feeling of something moving in the hair, itching, irritability and difficulty sleeping (they’re most active in the dark), sores on the head caused by scratching. There are many over the counter treatments that can be either used daily as a preventative or as needed to treat individual cases. Parents be sure to check your children’s hair routinely and treat as needed.
