Once a female louse has laid her first eggs on a new host, they will hatch after seven to ten days. From here, the nits will progress through their short life cycle consisting of three stages: egg, nymph and adult. The total lifespan of a louse is only 32-35 days, but after mating, each female can lay three to ten eggs per day. These eggs will then hatch and continue the cycle.
