How Long Do Head Lice Last?

Depending on the circumstances, adult head lice can survive for as long as 30 days. However, once they’re removed, they will die within 24 hours. Adult lice lay around 100 eggs over the course of their lifetime. Lice lay eggs on the head at the base of the hair shaft. The eggs hatch in four to 10 days. Lice nymphs emerge within nine to fifteen days. Adult lice mate every 24 hours.

To treat head lice, use an effective lice treatment. Many products will kill lice in a few days. However, you should remember not to use them on children under two years old. Also, avoid using conditioner on the affected area for at least two days after treatment. To get rid of head lice as quickly as possible, make sure to wash all your child’s clothing. You should also wash all the linens and use a dryer on high heat. You can also boil hair brushes and combs for 10 minutes. Using sealed plastic bags for these items will help kill lice as well.

Most people will not notice an infestation of head lice for at least a few weeks. However, some people may experience itching and rashes as a sign of the problem. Because lice are so small, they cannot survive without the warmth of the scalp. In addition, they need to stay close to the scalp to develop.
