Mold is a fungus that grows on (and breaks down) all types of organic matter. It can grow outdoors in soil, on wood, or on decaying plants and animals. Indoor mold can grow in a variety of areas that are exposed to moisture. For instance, it can thrive in carpet and on surfaces such as drywall, wood, insulation, clothes, leather, paper products, and food. Mold growing indoors can pose a health risk to you, your family, and your pets.
If you suspect that you have a mold problem, consult with a professional who can inspect and test your home.
