Mold will hide anywhere it is allowed, and it can sit dormant for a long time waiting for the right environment to grow. It may hide behind drywall, tile, flooring, or any number of surfaces. As long as the area remains dry, it is inactive and dormant. It will not cause health problems or decay.

Can dead mold make you sick?

Exposure to mold spores, both live and dead, and their byproducts like microbial volatile organic compounds (MVOCs), mycotoxins, connecting filaments, etc. can cause illnesses ranging from minor allergic reactions, respiratory problems like asthma and sinusitis, to more serious, life threatening illnesses.

Does dormant mold release mycotoxins?

For instance, when there is water intrusion in your home, whether it’s from flood damage or even a minor leak, within 48 hours, mold spores that have been dormant or have come from outside will start to feed on the wet materials in your home. These mold spores produce mold toxins called mycotoxins.
