Head Lice. ... Definition Head lice are tiny insects that feed on blood from the human scalp. An infestation of head lice, called pediculosis capitis, most often affects children and usually results from the direct transfer of lice from the hair of one person to the hair of another. ...
The adult female head louse lays her eggs (nits) at the base of the hair near the scalp. The eggs hatch in about 8 or 9 days. The newly hatched louse (nymph) will suck blood for food and shed its skin (molt) three times as it develops into an adult over a 10-day period.The young lice and adults live their entire lives on the head, feeding on blood. The entire life cycle takes about 3 weeks.ead lice live only about 30 to 40 days. They die in 1 or 2 days when removed from the head, and eggs die soon after being removed from the warm scalp. Head lice do not wander about rugs, furniture, or school buses seeking a host.
