When people think of toxic mold, black mold (Stachybotrys) is usually the first thing that comes to mind. But another dangerous and often overlooked mold is Chaetomium—a mold commonly found in buildings with long-term water damage.
What is Chaetomium?
- A highly allergenic and toxigenic mold often found on water-damaged drywall, wood, carpet, and insulation.
- Produces musty odors and has a cotton-like texture that turns blue-green to black over time.
- Often found alongside Stachybotrys (black mold), indicating severe moisture intrusion.
Why is Chaetomium a Serious Concern?
- Produces mycotoxins that may cause neurological issues, immune suppression, and chronic respiratory problems.
- Associated with sick building syndrome (SBS) and may cause headaches, fatigue, and cognitive dysfunction in some individuals.
Signs That You May Have Chaetomium in Your Home
- Strong, musty odor from walls, attics, basements, or crawl spaces.
- Peeling paint, warped walls, or soft drywall from hidden moisture.
- Potentially Increased allergy symptoms, headaches, or fatigue when indoors.
- History of leaks, flooding, or long-term moisture problems.
What Should You Do If You Suspect Chaetomium?
- Don’t rely on bleach—it won’t kill the mold at its roots.
- Get professional mold testing to confirm and locate hidden mold.
- Address the moisture problem immediately to prevent further growth.
- Use professional remediation techniques to ensure complete removal.
