How can lice be removed from clothing? - briefly
Wash garments in water of at least 130 °F (54 °C) and tumble‑dry on the highest heat setting for a minimum of 20 minutes; this kills both lice and their eggs. If laundering is impractical, seal the clothing in a freezer‑proof bag and keep it at –0.4 °F (‑18 °C) for 24 hours to achieve the same result.
How can lice be removed from clothing? - in detail
Lice can survive on fabrics for several days, so thorough decontamination of clothing is essential to prevent re‑infestation.
The most reliable method involves washing garments in hot water followed by high‑temperature drying. Use water that reaches at least 130 °F (54 °C); this temperature kills both adult lice and their eggs. After washing, place items in a dryer set to the highest heat setting for a minimum of 30 minutes. The combined effect of heat and agitation removes any remaining organisms.
If washing is not possible, alternative procedures include:
- Freezing: Seal the clothing in a plastic bag and store at –4 °F (–20 °C) for at least 48 hours. Extreme cold destroys lice and nits.
- Dry cleaning: Professional dry‑cleaning solvents are lethal to lice; ensure the service uses standard procedures.
- Steam ironing: Apply steam directly to the fabric for several passes, maintaining a temperature above 212 °F (100 °C). This method is effective for items that cannot be laundered.
For non‑washable accessories (hats, scarves, belts), place them in airtight containers for two weeks. Lice cannot survive beyond this period without a host, so isolation eliminates the risk.
After treatment, store cleaned clothing in clean, sealed bags until the household environment is confirmed free of infestation. Regularly launder bedding, towels, and undergarments in hot water to reduce the chance of recurrence.
By following these steps—hot water washing, high‑heat drying, or validated alternatives—clothing becomes safe for reuse, eliminating the source of lice in the home.
