Head lice can survive on a human host for approximately 30 days. They generally cannot survive longer than 24 hours off the host. A female louse lays 3-5 eggs a day. The eggs hatch in 7-10 days and it takes another 7-10 day for the louse to mature and lay their own eggs.
The eggs are glued to the hair shaft very close to the scalp. Head 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.ead lice live only about 30 to 40 days.
