Although head lice are a nuisance, they are not known to spread diseases.
Adult head lice are roughly 2 to 3 mm long.
Head lice infest the head and neck and attach their eggs to the base of the hair shaft.
Lice move by crawling; they cannot hop or fly.
Head lice infestation, or pediculosis, is spread most commonly by close person-to-person contact.
Dogs, cats, and other pets do not play a role in the transmission of human lice.
Both over-the-counter and prescription medications are available for treatment of head lice infestations.
