Microscopic dust mites live in your home and feed on skin flakes. They do not bite or spread diseases. However, The American College of Allergy, Asthma & Immunology lists dust mites as the most common cause of allergies from house dust. (Reference 1, Dust Mite Allergy, Paragraph 1,2) You can use over-the-counter cleaning products to kill dust mites in your home and prevent illness in susceptible people.
Wash bedding in very hot water and use a hot dryer to kill mites. Use a dehumidifier and vent fans to keep moisture from your home. Dust mites will not live in humidity below 55 percent. Use mite-proof covers for pillows and mattresses, and use an efficient filter on your furnace and air conditioner. (Reference 1, Tips for Reducing House Dust Allergens)Kill dust mites on toys, stuffed animals and small rugs by exposing them to sunlight.
