Louse Treatment and Prevention
Lice spread by hiding among shared headwear, clothing, and linens (such as blankets or pillowcases). When a new host uses or wears the infested fabric, the lice inside it attach to that host’s hair. The best way to avoid contracting or spreading lice is to be very careful about sharing clothing and headgear such as hats, helmets, or other protective clothing and equipment. Wash all clothing, linens, and equipment frequently, especially if it’s shared.
If you believe you have lice, the first thing you should do is remove them using a nit comb. If the nit comb can’t reliably remove all lice, consider seeing a doctor. You should also take a long and hot shower after using your nit comb to wash away any detached lice. After you’re finished treating yourself, thoroughly examine and wash all clothing and linens in the building. If you rent out clothing or other wearable equipment, you’ll have to check every piece of inventory thoroughly.
Lice Behavior and Diet
All three species of common louse feed on blood exclusively. They begin feeding as soon as they’re born and continue to feed through every developmental stage. Almost all lice will feed on their hosts multiple times in a single day, biting down in multiple different places around the same general vicinity of the body.
Head lice cannot survive more than two days without a blood meal. If they’re removed from a host, they will starve relatively quickly. If lice are in your building or clothing, it’s because they’ve been feeding recently.
