Dust Mites

Dust Mites

Dust mites are microscopic insects that feed on dander (skin flakes) that people and pets constantly shed. They thrive in warm, moist places such as mattresses, pillows and bedding. Dust mites are also found in carpeting, drapes, plush furniture and stuffed toys. People with dust allergies are allergic to the droppings (feces) of dust mites.

How to reduce exposure to dust mites

The more of these measures you take, the more likely there will be benefits:

  • Keep the humidity (moisture) level below 50%
  • Wash bedding in hot water every week
  • Use a washable blanket instead of a duvet/comforter
  • Encase your pillows, mattress and duvet/comforter in dust mite-resistant covers
  • Minimize stuffed toys and other things that collect dust
  • Vacuum regularly—use a vacuum cleaner equipped with a high efficiency particulate air (HEPA) filter or use a central vacuum system
  • If possible, replace carpeting with hard flooring
