How can clothing lice be eliminated at home? - briefly
Wash all infested garments in water at least 130 °F (54 °C) and dry them on high heat for 30 minutes; then treat remaining items with a lice‑killing spray or a solution of 1 % permethrin, and thoroughly vacuum the storage area. Repeat the process after a few days to ensure any newly hatched lice are eliminated.
How can clothing lice be eliminated at home? - in detail
Clothing lice, also known as body‑louse infestations, can be eradicated without professional intervention by following a systematic approach.
First, isolate all garments, bedding, and towels that have been in contact with the affected person. Place each item in a sealed plastic bag for at least 72 hours; the insects cannot survive without a blood meal for this period. After the isolation, launder the items in hot water (minimum 130 °F / 54 °C) and dry them on the highest heat setting for at least 30 minutes. For fabrics that cannot be washed, seal them in a bag and expose them to a tumble dryer on high heat for the same duration, or store them in a freezer at –4 °F (–20 °C) for 48 hours.
Second, treat the living environment. Vacuum carpets, upholstery, and cracks in flooring thoroughly; discard the vacuum bag or clean the canister immediately. Apply an insecticidal spray approved for indoor use to baseboards, mattress seams, and other crevices where lice may hide. Follow the manufacturer’s instructions regarding concentration, ventilation, and re‑application intervals.
Third, address personal hygiene. The individual should bathe daily with soap, focusing on the neck, armpits, and groin where lice tend to congregate. After bathing, dry the skin completely, as moisture promotes survival. If itching persists, an over‑the‑counter topical lotion containing permethrin 1 % can be applied to the skin according to package directions; repeat the treatment after seven days to disrupt the life cycle.
Finally, monitor for recurrence. Inspect clothing and skin daily for the next two weeks, looking for live insects or eggs. Repeat laundering and environmental treatment if any signs appear. Maintaining heated washing cycles and regular vacuuming will prevent re‑infestation.
