If you have an infestation, you should know how long they will live. Adult lice can live for up to 30 days on a person’s head, but once they’ve been removed, they’ll die within 24 hours. Lice eggs can hatch within a week or two if they’re in the right environment. Ideally, they need a similar environment to the scalp to hatch and live. However, they won’t survive more than a week if they don’t have access to blood.
You can prevent a head lice outbreak by following proper cleaning procedures. First, you should wash all clothing and bedding in hot water. Next, you should dry clean these items. You can also vacuum the entire home, including carpets, upholstered furniture, and car seats. Once you’ve finished cleaning, you should throw away the vacuum cleaner bags. You should also soak all your hair care products in a medicated shampoo and wash them in hot water to kill off any remaining head lice eggs.
You can also check your hair for nits. If you find them in your hair, they may be a sign of an active infestation. Lice lay their eggs at the base of the hair shaft, so it’s important to keep an eye out for these tiny creatures. If you find nits at least one-fourth inch from the scalp, you may have an active infestation. In addition to checking the scalp, you can also use a special lamp to reveal nits. These nits will glow pale blue.
