How can dust mites be fought? - briefly
Lower indoor humidity below 50 %, clean surfaces and vacuum with a HEPA filter, wash all bedding at ≥ 60 °C weekly, encase mattresses and pillows in allergen‑impermeable covers, and apply an approved acaricide for persistent infestations.
How can dust mites be fought? - in detail
Dust‑mite control requires a combination of environmental manipulation, regular cleaning, and targeted treatments.
Maintain indoor humidity below 50 % by using dehumidifiers or air‑conditioning. Low moisture limits mite reproduction, which thrives at 70‑80 % relative humidity.
Reduce temperature to 68 °F (20 °C) or lower when feasible; cooler conditions slow life‑cycle progression.
Encapsulate mattresses, pillows, and upholstered furniture with allergen‑tight covers that prevent mites from colonizing the interior fibers. Verify that seams are sealed and fabric is breathable.
Implement a cleaning schedule:
- Vacuum carpets, rugs, and upholstery with a HEPA‑rated machine at least twice weekly. Empty the canister into a sealed bag and discard immediately.
- Wash bedding, curtains, and removable covers in water ≥ 130 °F (54 °C) for a minimum of 10 minutes. If hot water is unavailable, use a dryer on high heat for at least 30 minutes.
- Steam‑clean hard floors and tile grout to reach temperatures that kill mites and their eggs.
Apply acaricidal agents where necessary. Choose products registered for indoor use, following label instructions for concentration and exposure time. For households preferring non‑chemical options, consider diatomaceous earth applied thinly to carpet edges and vacuumed after 24 hours.
Introduce air filtration. Install a whole‑house filter rated MERV 13 or higher, and place portable HEPA units in bedrooms and living areas to capture airborne particles released by mites.
Monitor progress by conducting periodic dust sampling with adhesive strips or disposable filters. Compare mite counts to baseline levels to assess the effectiveness of interventions and adjust strategies accordingly.
Professional pest‑control services can provide advanced treatments, such as fogging with regulated acaricides, when infestations persist despite comprehensive self‑management.
