Mold seeks MOISTURE, WARMTH, and FOOD, and all three conditions are necessary for it to grow. Mold is most likely to find a place to grow in a bathroom, basement or kitchen, but it can grow in other rooms if conditions are favorable. The climate where you live and the living habits in your household can affect the ability of mold to grow.
Mold spores can thrive and reproduce in wet or damp parts of your home: areas that have had flooding or where leakage has occurred in roofs, pipes, or walls, or areas around house plants, especially ones that sometimes are over-watered. In just 48 hours, a moist environment combined with room-temperature conditions and an organic food source can lead to mold growth.
Where mold can grow in your home:
After it gets the food it needs, mold can move to virtually any kind of surface. Mold prefers temperatures between 40 and 100 degrees Fahrenheit. If a warm enough area in your home is humid or damp and contains items that mold likes to eat, your home could develop a mold problem.
