Freezing is a viable solution to dust mites for items that cannot be washed. For things that can be washed, do so in hot water at a minimum temperature of 130 degrees Fahrenheit to kill the mites and remove the allergens. If items cannot be washed in hot water, place them in the dryer for at least 15 minutes at the same temperature. While the dryer kills the mites, it does not remove the allergens; wash and dry the items in the recommend temperature to get rid of them. Bedding can also be dried in the sunlight, which kills dust mites.

To reduce the occurrence of dust mites, fit mattresses, pillows and box springs with allergen-proof covers. Purchase new pillows every six months, as dust mites breed in pillows. If possible, replace carpeting with laminate flooring; if not, vacuum regularly using a vacuum with a HEPA filter. Use a dehumidifier or air conditioner to keep humidity at a low level, and limit the amount of clutter in the home.
