How can I treat furniture for scabies mites? - briefly
Wash all removable covers in water ≥ 55 °C (130 °F) and tumble‑dry on the highest heat setting. For non‑washable items, apply an EPA‑registered acaricide spray according to the label or seal the piece in a plastic bag for at least 72 hours to kill the mites.
How can I treat furniture for scabies mites? - in detail
Treating upholstered chairs, sofas, mattresses, and other household furnishings for scabies mites requires a combination of physical removal, thermal exposure, and chemical control.
First, isolate all infested items. Wash removable covers, pillowcases, and blankets in hot water at a minimum of 60 °C (140 °F) for at least 30 minutes, then tumble‑dry on high heat for another 30 minutes. Heat destroys mites and their eggs.
For non‑removable fabrics, apply these steps:
- Vacuum thoroughly. Use a vacuum equipped with a HEPA filter; run it over all surfaces, seams, and crevices for at least 10 minutes per piece. Immediately seal the vacuum bag or container in a plastic bag and discard it.
- Steam treatment. Direct steam at 100 °C (212 °F) onto upholstery, cushions, and wooden frames for 5–10 minutes per area. Steam penetrates fibers and kills both live mites and ova.
- Freezing method. Place smaller items (e.g., cushions, decorative pillows) in a freezer set to –20 °C (–4 °F) for a minimum of 72 hours. Prolonged exposure to sub‑zero temperatures eliminates the parasite.
- Chemical application. When heat or cold are impractical, use an acaricide approved for indoor use, such as 0.5 % permethrin spray or a pyrethrin‑based product. Apply according to the manufacturer’s instructions, ensuring even coverage of all surfaces. After treatment, allow the product to dry completely before re‑occupying the furniture.
- Encasement. Fit mattresses, box springs, and upholstered furniture with mite‑proof covers that have a zippered closure rated to block 99.9 % of arthropods. Keep the encasements sealed for at least two weeks to prevent re‑infestation.
After any chemical or steam procedure, ventilate the area for at least 30 minutes to disperse residual vapors. Repeat vacuuming and steaming once more after a week, as some eggs may hatch after the initial treatment.
Finally, maintain a routine cleaning schedule: vacuum weekly, wash bedding in hot water monthly, and inspect for signs of infestation regularly. Consistent preventive measures reduce the likelihood of recurrence and protect occupants from further exposure.
