2. Food: Mold is alive, and needs to eat. So usually you won’t see mold growing on plastic surfaces in your home. It will grow on wood and other organic surfaces. However, dirt in the carpet or on the floor can be a food source, so keeping your house super clean is smart.
3. Darkness: Mold likes the shadows of your home, and grows quickly in the dark. That’s why basements are often the first place mold is discovered.
