According to officials from the National Center for Environmental Health, many modern building materials, if exposed to moisture, can quickly become breeding grounds for mold. Imitation stucco, if wet, becomes mold food, as do wet cellulose materials, drywall, wallpaper, carpeting, fabric, paper products, ceiling tiles, wood and wood products. Despite the expense and inconvenience, Mr. Maxwell said he doesn't regret taking the elaborate precaution to rid his home of mold. Microscopic mold can feed on almost any substance so the introduction of moisture into an environment is the primary predictor of mold. Keeping surfaces and materials dry is the best defense in battling mold.
Mold is everywhere.
The most common indoor molds are cladosporium, penicillium, aspergillus and alternaria. Mold infestations can usually be seen or smelled. In most cases cleaning with diluted bleach is adequate for removal. Mold prevention should include keeping humidity in the building below 50 percent, using an air conditioner or dehumidifier during humid months. Be sure the home has adequate ventilation.
