Tips to Help Manage Triggers

If you have allergic asthma, it’s important to try to avoid your allergen triggers. There are many different ways people avoid triggers. Here are some tips to try:

Dust Mites

Dust collects everywhere. All the time. To help keep your exposure to dust mites at a minimum, you may want to:

  • Encase pillows and mattresses in dust mite-proof covers
  • Wash bedding and curtains at least once a week in hot (130-degree) water
  • Use allergen-elimination laundry detergent to help get rid of dust mites in your sheets and clothes
  • Replace fabric chairs and sofas with furniture that’s leather, wood, metal, or plastic
  • Remove carpeting and rugs in favor of wood, concrete, vinyl, or linoleum flooring
  • Be sure not to overuse humidifiers (as this can increase dust mites), and use dehumidifiers to keep humidity below 50% in your home

Pet Dander

Even people with pet-free homes can have a problem with pet dander. This is because it can be carried in on people’s clothing. To help reduce your exposure to pet dander, you can:

  • Clean your floors, rugs, and furniture regularly (pet dander can even stick to walls)
  • Change furnace filters regularly
  • Cover pillow and mattress with microfiber fabric that can help capture cat and dog allergens
  • Try not to visit the homes of people who have cats or dogs
  • Use a HEPA (high-efficiency particulate air filter) vacuum at least once a week
  • Use room air purifiers to capture airborne pet dander


Cockroaches like moist dark areas and anywhere they have access to food. To help keep them away, it’s a good idea to:

  • Keep garbage covered and food stored in containers with tight lids
  • Clean up dirty dishes, spills, and food crumbs right away
  • Fix all moisture problems, such as leaky faucets and drain pipes
  • Plug up any cracks you can find at the base of walls
  • Call in pest-control experts and use poison baits and traps for ongoing control
  • Use plastic boxes instead of cardboard boxes
  • Look for signs of cockroaches, including tiny droppings that appear to be similar to coffee grounds
