How can you kill dust mites? - briefly
Wash bedding, curtains, and other fabrics in water hotter than 130 °F or steam‑clean them to eliminate the organisms. Apply EPA‑registered acaricides (e.g., diatomaceous earth, benzyl benzoate, or essential‑oil sprays) for ongoing control.
How can you kill dust mites? - in detail
Dust mites thrive in warm, humid environments where skin flakes accumulate. Reducing their numbers requires a combination of physical removal, chemical treatment, and environmental control.
First, eliminate the food source. Wash all bedding, curtains, and removable upholstery in water hotter than 130 °F (54 °C) for at least 30 minutes. Dry items on high heat for a minimum of 20 minutes. Vacuum carpets, rugs, and upholstered furniture with a HEPA‑rated filter, moving slowly to allow deep suction. Discard vacuum bags after each use.
Second, lower humidity. Use a dehumidifier or air conditioner to keep indoor relative humidity below 50 %. Place hygrometers in bedrooms and living areas to monitor levels. Repair leaks and ensure proper ventilation in bathrooms and kitchens.
Third, apply acaricidal agents. Options include:
- Silica‑based powders (e.g., diatomaceous earth): Sprinkle on carpets, wait 24 hours, then vacuum.
- Benzyl benzoate or permethrin sprays: Follow label instructions, treat mattresses, pillows, and upholstered surfaces.
- Essential oil blends containing eucalyptus, tea tree, or lavender: Apply diluted solutions to fabric surfaces; note that efficacy varies.
Fourth, encase mattresses and pillows in allergen‑proof covers with zippered seams rated for dust‑mite protection. Seal seams tightly to prevent re‑infestation.
Finally, maintain a regular cleaning schedule. Vacuum weekly, wash bedding biweekly, and reapply acaricidal treatments according to product guidelines, typically every 2–4 weeks during high‑season periods.
Combining these measures creates an environment hostile to dust mites, dramatically reducing their population and associated allergic reactions.
