Head louse egg (nit) attached to hair shaft of host. Like most insects, head lice are oviparous. Females lay about three or four eggs per day. Louse eggs (also known as nits), are attached near the base of a host hair shaft. [11] [12] Eggs are usually laid on the base of the hair, 3–5 mm off the scalp surface.
The presence of nits alone, however, is not an accurate indicator of an active head louse infestation. Generally, white nits are empty egg casings, while brown nits may still contain viable louse larva. One way of determining the nit is to squeeze it between two fingernails; it gives a characteristic snapping pop sound as the egg bursts.
Pubic lice (Pthirus pubis) have three stages: the egg (also called a nit), the nymph, and the adult. They can be hard to see and are found firmly attached to the hair shaft. They are oval and usually yellow to white. Pubic lice nits take about 6–10 days to hatch. The nymph is an immature louse that hatches from the nit (egg).
