A mold allergy comes from mold spores that float in the air like pollen. Outdoor molds often appear during warmer months, but can be found year-round in the South and on the West Coast. Indoor molds shed spores all year, usually hiding in damp environments.
Outdoors: Soil, plants, rotting wood or dead leaves
Indoors: Basements, bathrooms, refrigerators and windowsills
Help prevent mold with regular bathroom, laundry room and basement cleanings.
Keep the humidity in your house below 50% to help discourage mold growth. If humidity is high, use air conditioners and dehumidifiers.
Use an exhaust fan over the stove and in the bathroom to remove extra humidity from cooking and showering.
Clean the refrigerator and empty the water pan regularly. Discard spoiling food promptly.
Mold doesn't like sunlight, so try to keep your curtains open during the day.
