Before you panic, let’s talk about it. Black mold can be sneaky, showing up in damp areas like —

bathrooms,

basements,
or even around windows.

It’s not just about how it looks—it can also affect your health and your home.

Let’s figure out what black mold really is, how to spot it, and what to do next.

What is Black Mold?

Black mold, also known as Stachybotrys chartarum, is a type of fungus. It grows in damp, warm, and dark places. Unlike regular mold, black mold is often slimy and dark in color.
