The Head Lice (Pediculus humanus capitis) Life Cycle consist of 3 stages i.e Eggs/Nits, Nymphs and Adult Head Lice. All these 3 stages last in about 40 to 50 days.

Head Lice Eggs/Nits

Head Lice reproduce by laying eggs/nits on the hair shaft close to the scalp of their host. The adult female louse can lay up to 4-10 eggs a day and about 120 eggs in the whole lifespan. The dark-brown color eggs are oval-shaped and about 0.8 mm in length. The eggs hatch in about six to nine days, depending on temperature.

Nymphs/Baby Lice

Newly hatched nymphs or baby lice feed on the blood of their host like adult lice and molt three times before reaching the sexually-mature adult stage. The nymphs look similar the adult head lice, but are smaller and have relatively pale color. The Nymph stage lasts about 9 to 12 days, depending on feeding conditions.
