How to get rid of Dust mites?

Killing all the dust mites at home is impossible. However, by using allergen-proof mattress and pillow covers, and regularly clean the house with a HEPA vacuum cleaner, we can control the number of dust mites.

Before thinking of how to get rid of them, we have to know under what condition they live happily.

Dust Mites likes:

  • warn and humid environment
  • eating our dead skin
  • they are very tiny so that they can hide inside our pillow, mattress, and toys

A female house dust mite can last up to 70 days, laying 60 to 100 eggs in the last 5 weeks of her life. Therefore, no matter how clean a home is, dust mites cannot be totally eliminated. However, we can control and reduce the number of dust mites by:

  1. Washing the bedding regularly
  2. Using a vacuum cleaner to clean the house regularly
  3. Control the humidity

Wash the bedding regularly

  • Use allergen-proof barrier covers on all mattresses, duvets and pillows. See allergen-proof products
  • Some bedding that is not encased in barrier covers, such as cover sheets, blankets should be washed regularly. Remember, the dust mite allergen dissolves in water so washing with cold water will wash the allergen away temporarily, but the mites will survive and produce more allergens. Washing with temperature 60 degrees celsius or above will kill mites.
  • Washable stuffed toys should be washed as frequently and at the same temperature as bedding. If the toy cannot be washed at 60 degrees place it in a plastic bag in the freezer for at least 12 hours once a month and then wash at the recommended temperature.
  • if possible, allergic children should not sleep in the bottom bunk bed where allergen can fall onto them.
  • carpeting is an ideal living environment for dust mites. Remove the carpet if possible. If removal is not an option, use a high-filtration vacuum cleaner to clean regularly. See below

Humidity Meter

Control the humidity

The amount of water in air is essential to dust mites. By reducing the humidity the number of dust mites can be controlled. Use a dehumidifier to keep indoor dry. if necessary use a dehumidifier to keep indoor humidity under 50% (but over 30%).
