How can I prevent asthma triggers at home?

The most important thing you can do is to control asthma triggers. The main asthma triggers that are in your home are dust mites, molds, pollens, pets, cockroaches, and household irritants. Secondhand tobacco smoke may also be a trigger in your home, especially for a child with asthma.

How can I protect myself against dust mites?

  1. Encase pillows, mattresses, and box springs with allergen-proof, zippered covers.
  2. Wash all bedding in hot water about once a week.
  4. Regularly change filters on heaters and air conditioners.
  5. Replace heavy, lined curtains or drapes with washable window coverings. Wash window coverings in hot water. Use plain window shades instead of mini-blinds.
  6. Dust all surfaces often, including lampshades and windowsills, with a damp cloth.
  7. Keep clutter under control. Toys and books should be stored in enclosed bookshelves, drawers, or closets.
  8. Replace traditional stuffed animals with washable stuffed animals.
  9. Keep all clothing in drawers and closets. Keep drawers and closets closed.
  10. Cover air ducts with filters or cheesecloth. Change these when soiled.
  11. Pillows and bedding should not contain feathers.
  12. Keep indoor humidity low (25-50%). Use a dehumidifier.

How do I stop mold and mildew from growing in my home?

  2. Use air conditioners when possible.
  4. Keep indoor plants out of bedrooms.
  5. When painting, add mold inhibitor to paint to prevent mold from growing.
  6. Avoid sources of outdoor molds, such as wet leaves or garden debris.

How do I control insects inside my home?

Many homes and apartments have cockroaches and other insects. Some people with asthma are allergic to these. To control these allergens in your home:

  1. Use roach baits or traps.
  2. Insect sprays can be used but should only be sprayed when no one is at home.
