How to clean bedding from lice? - briefly
Wash sheets, pillowcases, blankets, and any washable linens in water at 130 °F (55 °C) or hotter for at least 10 minutes, then tumble‑dry on high heat for 30 minutes. Seal non‑washable items in airtight plastic bags for two weeks to eliminate any surviving lice and nits.
How to clean bedding from lice? - in detail
Removing lice from sleeping surfaces requires a systematic approach that eliminates both live insects and their eggs. Begin by separating all contaminated fabrics from unaffected items. Place sheets, pillowcases, blankets, and any washable covers in sealed plastic bags to prevent re‑infestation during transport.
Wash the collected linens in hot water at a minimum of 130 °F (54 °C) for at least 10 minutes. This temperature kills nymphs and eggs that survive lower heat. After washing, tumble‑dry on high heat for a minimum of 30 minutes; the combined effect of heat and agitation guarantees complete eradication. For items that cannot be machine‑washed, soak in hot water for the same duration, then dry in direct sunlight for several hours, as ultraviolet exposure and heat are lethal to the parasites.
Treat the mattress and box spring with a steam cleaner capable of reaching 212 °F (100 °C). Direct the steam nozzle over seams, tufts, and edges, holding each spot for several seconds to ensure penetration. After steaming, vacuum the entire surface with a HEPA‑rated vacuum, discarding the bag or cleaning the canister according to manufacturer instructions to avoid releasing trapped eggs.
Apply an approved insecticide spray or powder labeled for head‑lice control to the frame, headboard, and any crevices near the sleeping area. Follow the product’s contact time guidelines, then wipe clean with a damp cloth. For non‑chemical alternatives, a mixture of equal parts water and rubbing alcohol can be sprayed, allowing it to air‑dry.
Finally, isolate the bedroom for 24 hours, keeping doors closed and limiting access. During this period, repeat vacuuming of the floor and any upholstered furniture to capture any newly hatched nits. After the isolation window, perform a second wash of all bedding at the same high temperature to confirm that no survivors remain. Regularly inspect the sleeping environment and repeat the cleaning cycle if any signs of lice reappear.
