How long do lice live? What is the lice life cycle?
Lice live approximately 40-50 days and go through 3 stages in their life cycle: Eggs Stage: The adult female louse lays the egg with a special glue that cements it to the hair shaft near the root. The eggs develop and hatch approximately 10 days later. Nymphs Stage: Once the louse hatches, it is called a nymph and is barely visible to the naked eye. The nymph cannot reproduce because it is not fully developed. After about 12 days, it becomes an adult. Adults Stage: The adult louse can lay up to 4-10 eggs a day – starting another generation of lice. The adult stage lasts about 28 days.
