Clear Your Home of Asthma Triggers

One way to control asthma symptoms is to clear your home of asthma triggers like those listed here:

Secondhand Smoke

  • Choose not to smoke in your home or car and do not allow others to do so either.

Dust Mites

  • Wash sheets and blankets once a week in hot water.
  • Choose washable stuffed toys, wash them often in hot water, and dry thoroughly. Keep stuffed toys off beds.
  • Cover mattresses and pillows in dust-proof zippered covers.


  • Consider keeping pets outdoors or even finding a new home for you pets, if necessary.
  • Keep pets out of the bedroom and other sleeping areas at all times, and keep the door closed.
  • Keep pets away from fabric-covered furniture, carpets and stuffed toys.


  • Wash mold off hard surfaces and dry completely. Absorbent materials, such as ceiling tiles and carpet, with mold may need to be replaced.
  • Fix leaky plumbing or other sources of water.
  • Keep drip pans in your air conditioner, refrigerator and dehumidifier clean and dry.
  • Use exhaust fans or open windows in kitchens and bathrooms when showering, cooking or using the dishwasher.
  • Vent clothes dryers to the outside.
  • Maintain low indoor humidity, ideally between 30 and 50 percent relative humidity.


  • Do not leave food or garbage out.
  • Store food in airtight containers.
  • Clean all food crumbs or spilled liquids right away.
  • Try using poison baits, boric acid or traps first before using pesticide sprays.
