What should be done with bedding if it contains lice? - briefly
Wash all sheets, pillowcases, blankets and other linens in hot water (≥130 °F/54 °C) and tumble‑dry on high heat for at least 30 minutes; seal any items that cannot be laundered in airtight plastic bags for two weeks or discard them. Clean the mattress and surrounding area with a lice‑killing spray or steam treatment before replacing the bedding.
What should be done with bedding if it contains lice? - in detail
If sheets, blankets, or pillowcases are found to host lice, begin by isolating them from other laundry. Place each item in a sealed plastic bag until treatment starts to prevent spreading.
Wash all contaminated fabrics in hot water at a minimum of 130 °F (54 °C). Use a regular detergent; add a small amount of bleach for white items if fabric care permits. Run a full wash cycle; avoid mixing with uninfested clothing.
Dry the laundered items on the highest heat setting for at least 30 minutes. Heat eliminates any surviving nits and adult insects. For items that cannot be tumble‑dried, place them in a sealed bag and expose them to direct sunlight for several hours, or use a portable heating unit that reaches 130 °F.
If the bedding cannot tolerate high temperatures, seal it in a heavy‑duty plastic bag for two weeks. Lice cannot survive without a host for more than 48 hours, and the extended sealed period ensures all stages die.
Vacuum the mattress, bed frame, and surrounding area thoroughly. Dispose of the vacuum bag or clean the canister immediately after use. Clean hard surfaces with a disinfectant spray to remove any stray eggs.
Consider using a mattress and pillow encasement designed to block insects. Replace or launder mattress protectors regularly. Inspect all household linens weekly during an outbreak and repeat the washing process if any signs of infestation reappear.
