To avoid giving lice to another person or getting them again, all headwear, scarves, coats, and bed linens should be machine-washed with hot water and dried in a dryer (at high setting) for at least 20 minutes. These items may also be dry cleaned, sealed in a plastic bag for 2 weeks, or sprayed with a disinfectant that kills lice. Brushes and combs should be soaked in hot water (hotter than 130 degrees F/54 degrees C) for 10 minutes, soaked in alcohol for 1 hour, or thrown away. Furniture and floors should be thoroughly vacuumed.
People who are in close contact with the infected person, such as members of the same household, should also be checked for lice and nits. Treatment may be considered to prevent infestation even if live lice are not found on them.
