ALLERGY TRIGGERS AND TIPS
Nasal Allergies and You: Allergy triggers and tips
Knowing and trying to avoid triggers is an important way to help manage your allergies.
But that's not always easy to do. Allergy triggers can be found everywhere—indoors and outdoors.
Year-round indoor allergy triggers include:
- Animal dander
- Indoor mold spores
- Dust mites
- Cockroaches
Seasonal outdoor allergy triggers include:
- Pollen from grasses, weeds, and trees
- Outdoor mold spores
Sometimes people can have both seasonal and year-round allergies. But there are simple things you can do each day to help manage triggers in and around your house. Explore the house below to learn more:

Kitchen
Kitchens can be home to a number of allergy triggers, including mold and cockroaches.
- Use an exhaust fan to reduce moisture when cooking.
- Keep garbage in an insect-proof container and empty it daily.
- Store food, even pet food, in a sealed container.
- Check for plumbing leaks under the sink.
- Wipe up moisture in the refrigerator and throw away moldy or expired items.
- Sweep or vacuum the floor each day.
Living Room
Soft surfaces, carpeting, and upholstered furniture in living areas can collect dust and other allergy triggers.
- Clean carpeting every week with a vacuum that has a small-particle filter.
- Consider using throw rugs that can be washed instead of carpeting.
- Use a damp cloth to clean up surface dust.
- Wash away mold on window frames and sills with a chlorine bleach solution (3/4 cup chlorine bleach to 1 gallon of water).
- Remove knickknacks and books that can collect dust.
- Do not sleep or lie down on upholstered furniture.
- Use washable window coverings made of plastic or cotton.
- Avoid wood-burning fireplaces.
Bedroom
Pet dander, dust mites, and scented sprays can be common allergy triggers in the bedroom.
- Keep pets out of the bedroom.
- Put mattresses and pillows in airtight covers.
- Wash all bedding in hot (at least
130°F) water each week. - Avoid overcrowding closets, and store clothes in a plastic garment bag.
- Cover air vents with layers of cheesecloth to filter large-size trigger particles.
- Remove upholstered furniture and items covered in fabric.

Child's Room
Your child can be affected by pet dander, dust mites, pollen, and other allergy triggers in his or her bedroom.

Outside
Pollen and mold around the yard can make life with allergies difficult.
- Wear protective clothing, such as a hat, glasses, gloves, and long sleeves to reduce exposure to pollen when working outdoors.
- Avoid using wood chips or mulch that can remain wet and invite mold to grow.
- Ask a family member who doesn't have allergies to mow the lawn, and keep the grass cut below 2 inches.
- Keep windows closed during and immediately after mowing.
- Limit gardening time to cool or cloudy days in the afternoon or evenings when pollen counts are lower.
- Remove dead leaves from your yard or gutters.
Bathroom
High humidity and moisture can make mold a problem in bathrooms.
- Use an exhaust fan to reduce moisture when bathing or showering.
- Replace carpeting with wood or linoleum flooring.
- Consider using tile or mold-resistant paint instead of wallpaper.
- Dry tubs and showers with a towel after each use.
