If you have an infestation of head lice in your household, it can feel impossible to get rid of it. Most “natural” home remedies, prescription treatments, and over-the-counter products are ineffective and will simply prolong your frustration. In order to learn how lice spread and how to get rid of them, you’ll need to understand the lice life cycle. Read on to learn more.
From Egg to Nymph
A head louse’s life begins as an egg, also called a nit. The adult female louse lays the egg and attaches it to a human hair strand using an exceptionally strong glue-like substance. Thanks to this “glue,” the nit will remain on the hair throughout all kinds of bathing, swimming, and hairstyling. Lice attach nits ¼ of an inch or less from the scalp so that it can be kept at an ideal temperature before hatching; that means nits farther than ¼ inch from the scalp most likely have already hatched or are not viable.
After approximately eight days, the egg hatches into a nymph. The nymph louse is not yet mature enough to reproduce. The nymph will feed on the host’s blood on a daily basis as it grows and undergoes three molts. Each molt—or shedding of the outer skin—takes approximately three days. This means that it only takes about nine days for a baby louse to become an adult louse!
At Lice Clinics of America – Northern IL, we professionally train our technicians to spot lice and nits in the hair and determine whether an active infestation is present. While it’s helpful to periodically check the hair for lice at home, distinguishing nits from dandruff and viable nits from empty or dead nits can be challenging. To save yourself the hassle, schedule a professional head check with us by calling 224-433-6087.
Continuing the Cycle
Once the louse finishes its third and final molt, it is then ready to mate and lay eggs. Female lice are capable of laying up to eight eggs per day for about three days, up until they die. That’s as many as 24 eggs per female louse. No wonder a case of head lice can be so hard to get rid of!
When it comes to transferring to a new host, head lice move quickly. They primarily spread to new hosts when there is direct head-to-head or hair-to-hair contact. As this contact occurs, usually during photos, hugs, or sitting and leaning against another person, lice can crawl from head to head in a matter of seconds. It’s easy to see how lice can spread rapidly between kids at school, at summer camp, and even at home.
