How can bed linen be treated for scabies mites? - briefly
Launder the sheets in water at ≥ 60 °C (140 °F) for at least 10 minutes, then tumble‑dry on high heat or seal them in a plastic bag for 72 hours to eradicate any remaining mites.
How can bed linen be treated for scabies mites? - in detail
Scabies mites cannot survive long without a human host; the environment, especially bedding, must be rendered inhospitable within 48–72 hours. Effective control requires a combination of thermal, mechanical, and chemical actions.
Washing at high temperature is the primary method. Use a washing machine set to at least 60 °C (140 °F) for a minimum of 30 minutes. This temperature reliably kills all life stages of the mite. If the fabric label permits, increase the temperature to 70 °C (158 °F) for added safety. Use a regular detergent; no special scabicidal additive is necessary.
Drying must follow immediately after washing. Employ a tumble dryer on the hottest setting for at least 20 minutes. The heat eliminates any residual organisms that might have survived the wash cycle. For items that cannot be tumble‑dried, place them in direct sunlight for several hours; ultraviolet radiation and heat together provide a comparable effect.
Mechanical removal assists the thermal process. Vacuum the mattress, box spring, and surrounding carpet with a HEPA‑filter vacuum. Empty the canister or bag into a sealed bag and discard it outside the home. This step extracts eggs and adult mites that may have fallen onto surfaces.
If laundering is impossible for certain textiles (e.g., delicate blankets, pillows), apply a scabicidal spray approved for fabrics. Follow the product label precisely: apply a uniform mist, allow the recommended contact time (usually 10–15 minutes), then air‑dry in a well‑ventilated area. Avoid over‑saturation, which can damage fibers.
Ironing provides an additional heat barrier. Pass a hot iron (minimum 150 °C/300 °F) over flat sheets and pillowcases after drying. The brief exposure to high temperature ensures any surviving stages are destroyed.
Isolation of untreated items prevents cross‑contamination. Store unwashed bedding in sealed plastic bags for at least 72 hours; mites die without a host within this period. Label bags clearly to avoid accidental reuse.
Finally, maintain a clean environment to stop re‑infestation. Wash personal clothing and towels daily at the same temperature, vacuum floors weekly, and limit close contact with infested individuals until they have completed treatment.
By integrating high‑temperature laundering, thorough drying, targeted vacuuming, approved chemical sprays, and temporary isolation, all bedding components become free of scabies mites and the risk of recurrence is minimized.
