To rid of head lice after an infestation, wash all linens and clothing that lice victims have touched, vacuum carpets and upholstery, and treat all family members for lice whether they have them or not, notes KidsHealth. Otherwise, untreated lice may still exist throughout the house.
The nits that hatch lice often remain on the head after treatment, and lice often still live in the pillows, sheets and blankets after the treatment has ended. As a result, all linens and clothing should be washed at a temperature of 130 degrees Fahrenheit and then placed in a dryer, on the hot cycle, for a minimum of 20 minutes, according to KidsHealth.
Items that can't fit into the washing machine, such as pillows, cushions, comforters and stuffed animals, as well as clothing that requires dry cleaning should all go to the dry cleaner. For items that should not go to a dry cleaner, placing them in airtight bags for 72 hours suffocates the lice. It's also necessary to vacuum carpets and upholstery throughout the house. Afterward, the vacuum cleaner bag should go into the outside trash bin, reports KidsHealth.
Any hair care items such as combs, hair bands and brushes require soaking in medicated shampoo or isopropyl alcohol for at least an hour, or the owner has the option of throwing them into the outside trash. All members of the household should get lice treatment to keep them from returning, as stated by KidsHealth.
