How fast do lice multiply?


Great question! A female louse can lay up to 100 eggs in her lifetime of approximately 30 days. A nit (egg) incubates for 10-14 days, when the nit hatches it becomes a nymph; it takes 7-10 days for a nymph to evolve into a sexually mature adult louse (capable of laying eggs).
