How to treat a pillow for mite infestation? - briefly
Wash the pillow in water at least 130 °F (or steam‑clean it) and dry on the highest heat setting, then encase it in an allergen‑proof cover. If the pillow remains heavily infested or damaged, replace it.
How to treat a pillow for mite infestation? - in detail
Dust mites thrive in the warm, humid environment of a pillow, feeding on dead skin cells and producing allergens that can aggravate respiratory conditions. Removing these organisms requires a combination of thermal, chemical, and preventive strategies.
First, expose the pillow to temperatures that exceed the mites’ tolerance. Washable pillows should be laundered on the hottest cycle the fabric allows, typically 60 °C (140 °F) or higher, for at least 30 minutes. After washing, dry the pillow in a dryer on a high‑heat setting for a minimum of 30 minutes. For non‑washable pillows, place them in a sealed plastic bag and bake in an oven at 70 °C (158 °F) for 30 minutes, ensuring the material can withstand the heat without damage.
Second, apply approved acaricidal agents when heat treatment is insufficient or impractical. Spray a dust‑mite specific insecticide evenly over the pillow surface, following the manufacturer’s dosage instructions. Allow the product to remain on the fabric for the recommended contact time, usually 15–30 minutes, before wiping excess residue with a clean, damp cloth. Ensure the pillow is fully dried before reuse.
Third, implement barrier methods to prevent reinfestation. Encase the pillow in a zippered, allergen‑proof cover made of tightly woven fabric (pore size ≤ 10 µm). The cover should remain sealed during sleep and be laundered weekly at high temperature. Reduce indoor humidity to below 50 % by using a dehumidifier or improving ventilation, as lower moisture levels inhibit mite reproduction.
Finally, assess the pillow’s condition regularly. Replace pillows that show signs of wear, loss of shape, or persistent odor, typically every 1–2 years for synthetic fills and every 3–5 years for natural fibers. Disposal should involve sealing the old pillow in a plastic bag before discarding to prevent accidental spread.
By integrating heat treatment, targeted chemicals, protective encasements, and environmental control, a pillow can be effectively cleared of dust mites and maintained in a low‑infestation state.
