Molds

Molds are microscopic fungi; their spores float in the air like pollen. Molds thrive in damp areas with decaying materials. There are many molds, the most common being Alternaria and Cladosporium.

Outdoor mold spores begin to appear after a spring thaw and peak in July through October. These molds can be found in soil, leaves on the ground and rotting wood.

Indoor molds (mildew) may be found in basements, bathrooms, refrigerators, garbage containers, houseplant soil, carpets, upholstery and even Christmas trees.
