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. Molds can be seen throughout the house, and can be found in most bathrooms. Mold growth can often be seen in the form of discoloration, and can be many colors-white, orange, pink, blue, green, black or brown.
