How to combat household dust mites? - briefly
Wash all bedding, curtains and washable fabrics weekly in water above 60 °C, encase mattresses and pillows in allergen‑tight covers, and keep indoor humidity under 50 % with a dehumidifier. Vacuum carpets, upholstered furniture and flooring regularly using a HEPA‑rated vacuum and eliminate removable rugs where possible.
How to combat household dust mites? - in detail
Dust mites thrive in environments where skin flakes, moisture, and food sources accumulate. Reducing these conditions interrupts their life cycle and lowers infestation levels.
- Remove bedding, curtains, and upholstered fabrics weekly; wash at temperatures of at least 60 °C (140 °F) for 30 minutes to kill adults and eggs.
- Encase mattresses, pillows, and box springs in zippered, allergen‑proof covers; replace yearly to maintain integrity.
- Keep indoor relative humidity below 50 % by using dehumidifiers, air‑conditioning, or ventilation fans, especially in bedrooms and living areas.
- Vacuum carpets, rugs, and upholstered furniture with a machine equipped with a HEPA filter; empty the canister or bag into a sealed container after each use.
- Sweep or mop hard floors with a damp cloth; avoid dry sweeping that disperses particles into the air.
- Reduce clutter that can harbor dust; store rarely used items in sealed plastic bins.
Chemical measures supplement mechanical actions:
- Apply acaricidal sprays containing benzyl benzoate, permethrin, or pyrethrins to carpets, cracks, and crevices; follow label instructions regarding concentration and re‑application intervals.
- Use dust‑mite powders (e.g., diatomaceous earth) on carpets and upholstery; leave for several hours before vacuuming to desiccate mites.
Air purification enhances overall control:
- Install HEPA air purifiers in high‑traffic rooms; operate continuously during waking hours.
- Replace HVAC filters with high‑efficiency models and clean ducts annually to prevent dust buildup.
Professional intervention may be necessary for severe infestations:
- Request a qualified pest‑management service to conduct a thorough inspection, apply registered acaricides, and provide a customized maintenance plan.
Consistent application of these practices creates an environment hostile to dust mites, minimizes allergen exposure, and sustains long‑term reduction.
