Outdoors, many molds live in the soil and play a key role in the breakdown of leaves, wood, and other plant debris. Without molds we would be struggling with large amounts of dead plant matter.
Molds produce tiny spores to reproduce.
Mold spores travel through the indoor and outdoor air continually. When mold spores land on a damp spot indoors, they may begin growing and digesting whatever they are growing on in order to survive. There are molds that can grow on wood, paper, carpet, and foods. If excessive moisture or water accumulates indoors, extensive mold growth may occur, particularly if the moisture problem remains undiscovered or un-addressed. If mold is a problem in your school, you must clean up the mold and eliminate sources of moisture.
