Types of Mold Found in Homes

There are different types of mold found in the home, but they all fit into one or more of the following categories:

  • Allergenic
  • Pathogenic
  • Toxigenic

Allergenic can trigger an allergic reaction in people with allergies, but can also cause symptoms in those without allergies. Pathogenic molds affect those with immune system disorders or serious illnesses.

Toxigenic molds are the most dangerous type. They can cause serious health problems in anyone, including healthy people.

Now, let’s dive deeper into the specific molds people may find in their houses. It is important to note that certain molds won’t also be visible to the naked eye. However, they typically can be identified with a virtual inspection from a company like Mold Busters.


Stachybotrys is more commonly known as black mold for its color. This is a toxigenic mold that blooms in wet areas.

You can find signs of this mold in places like drywall, wood, or stacks of leaves. If you find black mold in your home, you should call mold remediation services right away as it can cause severe health problems and symptoms.


Mucormycetes mold is the fuzzy white mold you’ll see that appears to have hairs. It lives in plants and soil but it can be accidentally brought into the home during the summer and fall seasons.
