Black mold typically refers to Stachybotrys Chartarum, which is one of several species of mold that produces a toxic byproduct called mycotoxins. Mycotoxins are created as the mold breaks down the building materials feeding its growth. Certain mycotoxins can cause health effects if they’re inhaled by humans or pets, particularly infants or those with pre-existing health conditions, which is why people sometimes refer to black mold as “toxic mold.”

Just like any type of mold, black mold requires constant moisture in order to grow. This means that mold could thrive in the aftermath of water damage from a flood or a burst water pipe. Similarly, issues with roof leaks, clogged gutters, or landscaping can lead to major moisture and mold problems. For black mold to survive, it needs the following:

• A nutrient source on a surface to grow on (e.g. drywall, carpet, wood, and ceiling tiles)
• Darkness
• Warmth
• At least 24 to 48 hours

Provided these conditions are met, mold can grow virtually anywhere. Ultimately, however, moisture is the most important factor. If your home or business has a problem with moisture, whether it’s condensation or water damage, mold can grow and begin damaging the materials on which it’s growing.

Stachybotrys chartarum is a greenish-black mold. It can grow on material with a high cellulose content, such as fiberboard, gypsum board, and paper. Growth occurs when there is moisture from water damage, water leaks, condensation, water infiltration, or flooding. Constant moisture is required for its growth.
