Frequently Asked Questions

Is Gliocladium (Gliocladium spp.) dangerous?

Gliocladium is classified as a low-risk, common mold with low allergenic potential. Primary health concerns include generally low health risk, possible allergen. Low; rarely associated with infection A professional assessment determines the extent and the right response for your property.

Where does Gliocladium grow in Gulf Coast homes?

Gliocladium commonly appears in wet wood, soil, damp drywall, cellulose materials. It thrives at 88-98% relative humidity with a water activity of 0.88-0.95 aw, conditions that are common across humid Louisiana and Mississippi Gulf Coast properties.

How do you identify Gliocladium?

Fast-growing green colonies that produce slimy spore masses, similar in look to Trichoderma Colonies are typically green, white, yellow-green with a cottony to powdery, fast-growing texture. Mild musty, earthy odor Confirmation requires professional sampling and laboratory analysis rather than visual identification alone.

What does remediation of Gliocladium involve?

Gliocladium typically calls for standard containment. Remove heavily colonized porous materials High — correct wood/cellulose moisture InspectaMold documents the conditions and provides an independent protocol so the underlying moisture source is corrected, not just the visible growth.
