How to treat clothing for clothing lice? - briefly
Remove the items, seal them in a plastic bag, and wash at 130 °F (54 °C) for a minimum of 30 minutes, followed by high‑heat drying for at least 20 minutes; if laundering is not feasible, store the garments sealed for two weeks to eliminate the parasites. This process eradicates the lice and prevents reinfestation.
How to treat clothing for clothing lice? - in detail
Clothing lice (Pediculus humanus corporis) survive only on fabrics; eliminating them requires a systematic approach that combines heat, chemical treatment, and preventive measures.
First, isolate all contaminated garments. Place items that can tolerate high temperatures in a dryer on the hottest setting for at least 30 minutes. The heat kills both adult insects and eggs. For fabrics that cannot be tumble‑dried, use a steam iron or a professional steaming device, ensuring the steam penetrates the material for a minimum of five minutes.
Second, apply an appropriate insecticidal wash. Use a laundry detergent that contains permethrin, pyrethrin, or a similar approved ectoparasiticide. Follow the manufacturer’s instructions for concentration and soaking time. If a chemical wash is not desired, add a cup of white vinegar or a half‑cup of borax to the wash cycle; both substances create an inhospitable environment for the parasites.
Third, after washing, dry the items on high heat for another 20–30 minutes. For items that must air‑dry, expose them to direct sunlight for at least six hours, as ultraviolet radiation reduces lice viability.
Fourth, treat storage areas. Vacuum closets, drawers, and suitcases thoroughly, then wipe surfaces with an EPA‑registered disinfectant. Seal non‑washable items (e.g., hats, shoes) in airtight bags for two weeks; lice cannot survive without a host beyond this period.
Finally, implement ongoing prevention:
- Rotate clothing after each use; avoid leaving garments piled for long periods.
- Store clean clothes in sealed containers.
- Conduct regular inspections of clothing, especially after travel or contact with infested environments.
- Educate household members about the need for immediate laundering of any suspect items.
By integrating high‑temperature drying, targeted chemical washes, thorough drying, environmental decontamination, and consistent preventive habits, clothing lice infestations can be eradicated and future occurrences minimized.
