To tell if black mold may be growing in your home, just follow your nose. A musty, earthy smell, like dirt and rotting leaves, is a telltale sign of mold's presence. Stachybotrys smells especially strong. All molds need food, water and a dark, stagnant environment with temperatures that neither freeze nor boil to grow.

Is drywall ruined if it gets wet?

While drywall is pretty sturdy, when it's exposed to water for too long it can get damaged. It may lose its structural integrity, becoming soft and weak. Depending on what category of water drywall is exposed to, and how wet it got, you may be able to save it. Speed is critical to avoiding mold damage, though.

What type of cancer does mold cause?

Mold spores also produce toxins (mycotoxins) that can affect the lungs, skin, and nervous system. But we have no definitive evidence linking them to specific diseases — and no evidence that mold spores cause lung cancer. Exposure to tobacco smoke is the biggest risk factor for lung cancer.

How can you tell if mold is water damaged?

Most mold is unmistakable, but sometimes small or largely hidden growths just make a surface look dirty. A quick test for mold can be done when you dip a swab in diluted bleach (1 part bleach, 16 parts water) and dab it on the wall. If the spot quickly lightens (or keeps coming back after cleaning), assume it's mold.
