You should examine your child’s head, especially behind the ears and at the nape of the neck, for crawling lice and nits if your child exhibits symptoms of a head lice infestation. If crawling lice or nits are found, all household members should be examined for crawling lice and nits every 2–3 days. Persons with live (crawling) lice or nits within ¼ inch or less of the scalp should be treated.

Head lice can be a nuisance but they have not been shown to spread disease. Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice.
