How do head lice live? Head lice are small, parasitic insects that feed on the human blood. They typically stay close to the scalp and behind the ears, but they can also be found in eyebrows and eyelashes. Adult lice are about two to three millimeters long and have six legs. They can stick to human hair and lay their eggs at the base of the hair shaft.
You can prevent head lice by not sharing personal items, washing clothing that was worn within the past 48 hours, and thoroughly cleaning carpets and furniture. You should also wash stuffed animals, hats, and other personal items regularly. It is best to wash all of these items in hot water and dry them in a hot dryer. If you can’t wash these items, you should put them in a plastic bag for at least two weeks. In addition, you should soak hairbrushes in hot water before using them.
Children are most at risk for head lice. If your child has head lice, you should consider keeping them home from school until they’re treated. If you think your child has them, you can check their head using a magnifying glass to look for live lice.
