If you're allergic to mold, you may feel like you’re fighting a losing battle. Mold thrives in so many places, indoors and out. But you can take steps to limit your exposure. Pay attention to outdoor spore levels. When they’re high, don’t spend as much time outside. The National Allergy Bureau sends out email alerts to help you keep track.

Think Before You Go

Mold is more likely to be in certain types of stores and businesses. Examples include greenhouses, farms, flower shops, construction sites, and antique shops. Before you go in, take your allergy medication or bring a dust mask.

Know What to Avoid

Uncut fields and piles of damp leaves are prime places for mold. Stay away if you can. If you need to mow the lawn, dig up plants, or rake leaves, wear a dust mask. When you come back inside, take a shower to wash away any mold spores that hitched a ride on your skin and hair.

Take the Moisture Out

Take the Moisture Out

Make your home less mold-friendly. The key is to control the amount of moisture in the air. Dehumidifiers and air conditioners will help. The humidity needs to be below 60%. Between 35% and 50% is even better. You can buy an inexpensive meter to measure your home's humidity at a hardware store.

Keep It Clean

Keep It Clean

Mold can thrive in warm, damp bathrooms and humid kitchens. A clean surface isn't a breeding ground, but those with a little soap scum or grease are. An exhaust fan or open window in the bathroom will help cut down on humidity. In the kitchen, keep an eye out for mold in refrigerator drip pans, door seals, and garbage pails.

A damp cellar can be a moldy place. Lower the humidity by turning up the thermostat or running a dehumidifier. Choose flooring such as linoleum or concrete that doesn’t hold in moisture. And take a look at what you’re storing down there: Mold can grow on old papers, bedding, and clothes. Keep things in air-tight, water-proof containers, so mold can't sneak in.

Get the Mold Out

Get the Mold Out

If you spot mold on a hard surface in your home such as glass, plastic, or tile, clean it using a bleach solution, soap and water, or a commercial product. Still, it's not enough to just clean it. You need to find the source of it to keep it from happening again. For mold on drywall, you might want to get professional advice.

Filter Your Air

Filter Your Air

An air-conditioning unit with a high-efficiency particulate air (HEPA) filter attachment will trap outdoor mold spores and keep them out of your house. It’s also important to keep AC drip pans and drain lines clean so that mold can’t grow in them. Make sure your dryer vents are clear as well.

Act Fast

Act Fast

Quick action pays off. If a leak or spill leaves the rug wet, dry it within 48 hours to keep mold from growing. Mop water off the floor and fix leaky pipes and faucets right away. Do your gutters need cleaning? Don't delay. The moist leaves inside are a breeding ground.

Check Your Landscape

Check Your Landscape

Do everything you can to keep your home’s foundation dry. Rake dead leaves from around the base of your home. You might also want to clear out thicker shrubs and plants from that area. Make sure rainwater drains away quickly from your house. These steps are extra-important if you live in a shady spot, since a lack of sun means it takes longer for water to dry out.
