Start with the person, not the house
Head lice mainly spread through direct hair-to-hair contact. Correctly treating an active infestation and checking close contacts matter more than scrubbing every surface.
Focus household cleaning on items the infested person used during the two days before treatment.
- Wash clothing, towels, bedding, and hats in 130°F water and dry on high heat.
- Soak combs and brushes in 130°F water for 5–10 minutes.
- Seal items that cannot be washed or dry-cleaned in a plastic bag for two weeks.
A quick vacuum is enough
Vacuum the floor, couch, car seat, and other places where the person recently sat or lay. The chance of getting lice from furniture or carpet is small, so hours of repeated cleaning are unnecessary.
Never use pesticide foggers
CDC warns against fumigant sprays and fogs. They are not necessary and can be toxic if inhaled or absorbed through the skin.
