Lice can live anywhere in a home where they can burrow deep and hide. Laundry is a perfect place for them to do that. Laundry can quickly become infested with lice if a person who has head lice has been wearing or sleeping on any of the items in the basket or pile. There are some steps that need to be taken to ensure that you kill all of the lice in your laundry.


Step 1

Keep all of your laundry in the laundry area or room until all of it can be washed.

Step 2

Place items that cannot be washed in hot water into bags and tie them tightly. They will need to remain in the bags for at least two weeks to kill the lice.

Step 3

Place anything that can be washed in hot water into medium loads in your washing machine. Do not overfill the machine because it is important that all of the possible lice are exposed to the hot water.

Step 4

Pour in your usual laundry detergent, and set the washing machine on its hottest setting.


Killing the lice in your laundry is only a part of effective lice control. Treat the rest of your home including people, furniture and flooring as well.

Lice can very easily travel from one person or item to another person or item, so keep treated items/people/areas away from untreated items/people/areas.
