Mold is present almost everywhere—both indoors and outdoors. It can enter a residential or commercial space through the air or be carried indoors on clothes. It is a fungus that is fed by moisture and is an organic food source. Some mold is not harmful including mold in the foods we eat (mushrooms, yeast) and mold used to make medicine (penicillin). Other types of mold can be very hazardous to your health.
Indoor mold is commonly found in places like attics, basements, crawl spaces, and storage areas. Since mold is fed by moisture and is an organic food source it can happen anywhere. This can be around a roof leak, leaky pipes or as a result of seasonal flooding. Even high indoor humidity can encourage mold growth.
Black mold is a common type of mold. Although many types of mold can be black in color, black mold is a specific type known as stachybotrys. Other types of mold include aspergillus, chaetomium, cladosporium and penicillin. Learn tips on how to prevent mold.
