The diagnosis of a head lice infestation is best made by finding a live nymph or adult louse on the scalp or hair of a person. Because nymphs and adult lice are very small, move quickly, and avoid light, they can be difficult to find.
Do head nits move?
Head lice crawl, but they can't jump or fly. Head lice often spread from one person to another by direct head-to-head contact, often within a family or among children who have close contact at school or play.Do lice eggs move?
Lice eggs hatch 1–2 weeks after they're laid. After hatching, the remaining shell looks white or clear and stays attached to the hair shaft. This is when it's easiest to spot them, as the hair is growing longer and the egg shell is moving away from the scalp.How quickly do nits transfer?
Few nits: less than 2 weeks.An adult louse climbs onto your hair and lays about 6 to 10 nits a day, which take about 9 days to hatch. So if you look on the scalp and see no visible adult lice and several small nits, it's likely that you've caught lice in the earlier stages and had them for less than 2 weeks.
