Sensitive individuals should avoid areas that are likely to have mold, such as compost piles, cut grass, and wooded areas. Inside homes, mold growth can be slowed by controlling humidity levels and ventilating showers and cooking areas.

Using an air conditioner or dehumidifier will help you keep the levels low, however, bear in mind that humidity levels change over the course of a day with changes in moisture levels and air temperature. Run a dehumidifier in enclosed spaces such as basements. Be sure the home has adequate ventilation, including exhaust fans. Add mold inhibitors to paints before application. Clean bathrooms with mold or mildew killing products. Do not carpet bathrooms and basements. Remove or replace previously soaked carpets and upholstery. ....
