Facts and Information about Lice

It is important to understand the stages of the life cycle:

Life cycle of the lice

Nits (eggs)
 Head lice lay their eggs about 1/4th inch from scalp where it is warm. Each egg is attached to the hair shaft with glue made by the adult female. The oval casings, or shells, of these eggs are called nits. Nits are often difficult to see because they are nearly colorless and smaller than a pinhead. They may easily be confused with bits from the hair follicle, dandruff, or droplets of hairspray. The shells are so hard that they can actually stay in the hair for many months after the egg has hatched. It is difficult to dislodge the nits from the hair shaft.

After seven to ten days, newborn lice, which are known as nymphs, hatch from the louse eggs. Nymphs start to feed on your blood almost immediately through a tube that pierces your skin. After moulting (shedding their skin) over the course of 7-10 days, they become adult lice. During this time, they stay very close to the warm and dark scalp

Adult Lice
As soon as nymphs mature into adult lice, they begin mating. The female lays 3-10 eggs per day and may lay up to 100 in her lifetime. Each adult louse lives up to 30 days. To stay alive, it must feed on human blood every three hours which means that it bites your scalp between 4 and 8 times per day.
A fully grown head louse is flat, wingless, a greyish brown, and about the size of a sesame seed. It has 3 pairs of legs with powerful claws at the ends that help it grip firmly to the hair. This makes it hard to comb them out of your hair. If they do happen to fall out of your hair, they can stay alive for up to 3 days.
