When you know what you are allergic to – or what your asthma triggers are – you can take steps to get rid of or avoid those things in your home.

Keep allergens and irritants out of the bedroom.

Control moisture to prevent mold.

Keep your home dry to prevent mold. Mold can start to grow in wet or damp places within just 1 or 2 days.

If you rent your home and there's mold in it, you may be able to ask your landlord or property manager to clean up the mold. Check with your local county or state health department to learn more about your rights.

What if the air in my home is too dry?

While moist (wet) air can lead to mold, dry air can be uncomfortable.

If the air in your home is dry in the winter, you can use a humidifier. Just be sure to still keep the humidity level between 30 and 50 percent.

Keep pests out of your home.

Rodents (mice and rats) and cockroaches can trigger allergy or asthma attacks if you are allergic to them. Take these steps to help prevent pests:

Make a no-smoking rule in your home.

Cigarette smoke, including secondhand smoke, can make asthma worse. And babies who live in homes where people smoke are at higher risk of developing asthma. 

If you have guests who smoke, ask them to smoke outside. If you smoke, make a plan to quit today.

Avoid burning wood inside your home.

Breathing too much smoke from a wood-burning stove or fireplace can cause an asthma attack. If you can avoid it, don’t burn wood in your home.
