How can I kill bed mites? - briefly
Wash all bedding and clothing in water of at least 60 °C (140 °F) for 30 minutes, then dry on high heat; vacuum mattresses and surrounding areas regularly with a HEPA‑filter vacuum. Apply an EPA‑registered acaricide or a steam cleaner to treat fabric surfaces, and maintain indoor humidity below 50 % to prevent re‑infestation.
How can I kill bed mites? - in detail
Eliminating bed mites requires a combination of physical removal, environmental control, and, when necessary, chemical treatment.
First, remove the insects directly from the sleeping area. Wash all bedding, curtains, and removable fabrics in water hotter than 60 °C (140 °F) for at least 30 minutes. Dry items on high heat for a minimum of 20 minutes. For items that cannot be laundered, place them in a sealed plastic bag and expose them to direct sunlight for several hours; ultraviolet radiation and heat reduce mite populations.
Second, reduce the environment that supports their survival. Maintain indoor relative humidity below 50 % using dehumidifiers or proper ventilation, as mites thrive in moist conditions. Vacuum the mattress, box spring, and surrounding floor surfaces with a HEPA‑filter vacuum cleaner daily; discard the vacuum bag or clean the canister immediately after use. Install allergen‑proof encasements on mattresses and pillows, sealing all seams to prevent re‑infestation.
Third, apply targeted acaricides when mechanical methods are insufficient. Use products registered for indoor dust‑mite control, following label instructions precisely. Spot‑treat seams, crevices, and upholstered furniture with a spray containing benzyl benzoate, permethrin, or pyrethrin, allowing the recommended contact time before wiping or vacuuming. For severe cases, engage a licensed pest‑management professional who can apply residual treatments safely.
Finally, sustain preventive measures. Perform weekly laundering of bedding, monthly vacuuming of upholstered items, and quarterly deep cleaning of carpets with steam at temperatures above 70 °C (158 °F). Regularly inspect sleeping areas for signs of resurgence, such as increased allergy symptoms or visible mite debris, and repeat the above steps promptly if detection occurs.
