Mold can grow just about anywhere, but it prefers warm, humid, or moist environments. It can also be found in drier environments with poor ventilation or air flow.

Mold appears as thread-like clusters of small, black, brown, green, or white dots. You might see them on the walls of your bathroom or basement. A musty odor is often associated with mold growth. If you’ve seen it or smelled it in your home, you might have a mold problem.
