Wash clothing, bedding, and washable items in hot water (≥130 °F) and dry on the highest heat setting; non‑washable items should be sealed in a plastic bag for two weeks or treated with a lice‑killing spray. Thoroughly vacuum carpets and upholstery, then discard the vacuum bag or clean the canister.
How to treat items after lice? - in detail
After an infestation, every object that may have contacted the insects must be decontaminated to prevent re‑infestation. The following procedures cover clothing, bedding, personal accessories, and household items.
- Laundry – Wash all washable fabrics in hot water (minimum 130 °F/54 °C) and dry on high heat for at least 20 minutes. If hot water is unavailable, soak items in a solution of 1 part detergent to 4 parts water for 30 minutes, then rinse thoroughly.
- Non‑washable textiles – Place blankets, comforters, and delicate garments in a sealed plastic bag for two weeks. The insects cannot survive beyond 48 hours without a host, so the extended isolation ensures death.
- Hard surfaces – Vacuum carpets, upholstery, and mattresses using a vacuum equipped with a HEPA filter. Immediately discard the vacuum bag or clean the canister to avoid spreading viable eggs.
- Small accessories – Soak hairbrushes, combs, hats, and scarves in hot water (130 °F/54 °C) for 10 minutes, then rinse and dry on high heat. Items that cannot be soaked should be placed in a sealed bag for two weeks.
- Electronic devices – Wipe screens, keyboards, and remote controls with a cloth dampened in 70 % isopropyl alcohol. Avoid excess moisture that could damage circuitry.
- Furniture and mattresses – Apply a steam cleaner that reaches at least 212 °F/100 °C. Steam penetrates seams and cracks where eggs may reside. Allow treated surfaces to dry completely before reuse.
- Discarded items – Permanently remove infested items that cannot be decontaminated, such as heavily soiled pillows, stuffed animals, or worn‑out clothing. Place them in a sealed bag before disposal.
Complete the decontamination process before reintroducing the individual to the environment. Re‑treat any item that shows signs of re‑contamination. Consistent application of these measures eliminates the risk of recurrence.
