Female lice that are approximately 7 days old have generally reached reproductive maturity. At this point in their life they lay seven to 10 takes a day. The eggs are usually called nits. The eggs/nits are a white-translucence color and are very close to the scalp. The nits require a fairly constant temperature range so they are placed within 1 inch of the scalp preferably in a congested area of hair.
When the adult female louse lays the egg on the hair shaft she uses a glue like substance to attach it. As the hair grows, so the nits (or their empty shells) are carried away from the scalp and are more easily visible. Nits can often be mistaken for dandruff, flakes of dry skin or other small items caught in the hair.
