How To Get Rid Of Dust Mites

Reducing dust mites in your home requires a multi-faceted approach, especially in the bedroom where they are most concentrated[1]. Here are effective methods to help remove dust mites and lower their impact:

  • Encase mattresses, pillows, and comforters in dust-mite proof covers. These allergen-impermeable covers, made from tight-weave or plastic materials, prevent dust mites from inhabiting bedding[1][2][5]. Wash these covers and all bedding every 1–2 weeks in hot water (at least 130°F/54°C) to kill mites[2][3][7].
  • Remove or minimize fabric items that hold dust mites. Replace wall-to-wall carpeting, heavy curtains, and upholstered furniture with hard flooring, blinds, and leather, vinyl, or wood furniture[1][2][3][6]. Opt for washable rugs and synthetic pillows or comforters, which tolerate regular hot washing[3].
  • Vacuum regularly using a HEPA filter vacuum cleaner. This helps trap dust mites and their waste products from carpets, rugs, and furniture. Vacuum carpets and soft furniture at least once or twice a week, including seams and edges[1][5][8]. Certified Asthma & Allergy Friendly® vacuums are especially effective. If you are allergic, wear a mask or let someone else do the cleaning[2][3].
  • Maintain low indoor humidity. Dust mites thrive in humidity above 50%. Use dehumidifiers or ventilation to keep indoor humidity below 45% if possible[1][7]. Ventilating during dry weather also helps.
  • Damp dust surfaces and mop hard floors. Wipe surfaces weekly with a damp or electrostatic cloth, not a feather duster, to trap rather than spread dust[3][4]. Clean non-carpeted floors with a damp mop at least weekly[4].
  • Wash and care for soft items frequently. Wash blankets, doonas, and soft toys in hot water. If washing is not possible, freeze soft toys in a plastic bag for 24 hours to kill mites, although this doesn’t remove allergens[3][5]. Sun-dry rugs and blankets outdoors if feasible, as direct sunlight kills dust mites[7].
  • Declutter and minimize dust-trapping objects. Store items in closed containers and keep rooms tidy to reduce surfaces where dust mites accumulate[5].
  • Use air purifiers with HEPA filters. Air purifiers can help remove airborne mite allergens, particularly in bedrooms and high-traffic areas. Replace the filters regularly for maximum effectiveness[5].
  • Steam-clean carpets and bedding when possible. Steam and vapor cleaning can reduce dust mite populations and deeply penetrate fabrics without adding extra moisture[7].

Some frequently marketed methods, such as chemical sprays, air filters (not HEPA), electric blankets, and ion generators, have little or no proven benefit in reducing dust mite numbers or their allergens[3].
