how long does it take for lice to die when not in hair
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.he 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.
