Molds are simple, microscopic organisms whose purpose in the ecosystem is to break down dead materials. Molds can be found on plants, dry leaves, and on just about every other organic material. Order MoldSmart tm Some molds are useful, such as those used to make antibiotics and cheese. Some molds are known to be highly toxic when ingested, such as the types that invade grains and peanuts. Most of the mold found indoors comes from outdoors.
Molds reproduce by very tiny particles called spores.
The spores float in on the air currents and find a suitable spot to grow. Spores are very lightweight and can travel on air currents. If mold spores land on a suitable surface, they will begin to grow. It is usually these mold spores that cause allergic reactions. Molds need three things to thrive- moisture, food and a surface to grow on.
