Toxic Molds
Produce mycotoxins—chemical poisons that can cause serious health problems. The most well-known is "black mold" (Stachybotrys). Requires professional handling.
Toxic molds (toxigenic molds) release mycotoxins into the air—chemicals that can harm even healthy people. Stachybotrys chartarum, often called "black mold," is the most notorious example. Not all dark mold is toxic, but if you suspect it, get a professional inspection immediately.
If you experience unexplained respiratory symptoms or neurological issues, consult a physician and mention potential mold exposure.
Common Toxic Species
Stachybotrys chartarum
Dark greenish-black, slimy texture. Grows on water-damaged cellulose materials.
Aspergillus versicolor
Yellow-green to gray. Produces sterigmatocystin, a carcinogenic mycotoxin.
Certain Penicillium Species
Blue-green. Some species produce ochratoxin A and other harmful mycotoxins.
Where Mold Can Thrive
Mold can grow anywhere moisture and organic materials are present. Common problem areas include:
Water Damage & Leaks
Areas with water damage or past leaks, including around pipes, windows, and roofs
HVAC Systems
Air handlers, duct interiors, condensation pans, and filters
