Black mold, also called Stachybotrys chartarum, may create toxic chemicals as it grows, called mycotoxins. This means you and your family could become quite sick from an exposure. It could cause respiratory problems and long-term health issues. Regular mold rarely is toxic, but you may have an allergic reaction to it. Black mold is often dark colored with a fuzzy texture, but it sometimes can be green or another color. Regular mold can be almost any color. Don’t ignore any mold infestation in your home, regardless of whether it’s black or regular mold.
