What to do with bed linen if it has lice? - briefly
Wash the sheets in water at a minimum of 130 °F (54 °C) and tumble‑dry on high heat for at least 30 minutes to eradicate lice and their eggs. If the material cannot tolerate those temperatures, seal it in an airtight bag for two weeks or replace it outright.
What to do with bed linen if it has lice? - in detail
If bedding becomes infested with lice, immediate action prevents spread to clothing, furniture, and other occupants. The following protocol eliminates the parasites and protects the living environment.
-
Isolate the contaminated items
- Place sheets, pillowcases, blankets, and any washable fabrics in a sealed plastic bag. Keep the bag closed until processing begins.
-
Wash at high temperature
- Use the hottest setting the fabric tolerates, typically 130 °F (54 °C) or higher.
- Add a full‑dose of detergent; consider a lice‑specific laundry additive if available.
- Run a complete rinse cycle to remove residues.
-
Dry thoroughly
- Transfer washed items to a dryer set to the highest safe heat for the material, at least 30 minutes. Heat kills any surviving nits and adult lice.
-
Treat non‑washable textiles
- Seal items such as comforters, heavy curtains, or delicate fabrics in airtight bags for two weeks; lice cannot survive without a host beyond 48 hours.
- Alternatively, apply a professional steam‑cleaning service that reaches temperatures above 130 °F.
-
Vacuum surrounding surfaces
- Vacuum mattresses, box springs, bed frames, and nearby furniture. Empty the vacuum canister into a sealed bag and discard it outside the home.
- Use a brush attachment to dislodge eggs from seams and crevices.
-
Apply insecticidal treatment if necessary
- For persistent infestations, use an EPA‑registered lice spray on hard surfaces following label instructions. Avoid direct contact with skin and bedding that will be reused.
-
Prevent re‑infestation
- Store cleaned linens in sealed containers.
- Inspect all household members regularly; treat any additional cases promptly.
- Maintain a routine of washing bedding weekly at elevated temperatures.
By following these steps, contaminated linens are rendered harmless, and the risk of further lice transmission is minimized.
