Common Types of Molds That May Be Lurking in Your Home

While it is normal to find mold everywhere and it’s not always harmful, certain types of mold can pose serious health risks to you and your family if present in your home. Here are the common dangerous molds:

  1. Stachybotrys or Black Mold

This is one of the most dangerous types of mold. It can cause flu-like symptoms, headaches, diarrhea, and in severe cases, respiratory damage. This mold is dark in color; it can be grey, black or dark green. It is common in damp areas of your home and has a musty odor.

  1. Chaetomium

Chaetomium mold is almost similar to black mold and is commonly found in areas that are wet and dark. In homes, it is usually in carpets, drywall, wallpaper, and baseboards. Chaetomium spores can cause red and watery eyes, breathing problems, and in severe instances, neurological damage.

  1. Aspergillus

Aspergillus spores are found in the air we breathe every day and are dangerous to people with compromised immune systems. Exposure to its spores can cause allergic reactions and lung infections.

  1. Penicillium

This is abundant in many everyday environments and can cause asthmatic symptoms, bronchitis, and other respiratory problems.

  1. Fusarium

Expect to find Fusarium in plants and soil, carpeting, and inside drywall. Although quite rare, you or your family member can develop an eye infection from fusarium spores.

  1. Alternaria

This allergy-causing mold is present in summer and spring. It is usually found in electric cables, building materials, canvas, and cardboard.

Can I Tell What Kind of Mold I Have by the Color? What Does the Color of Mold Indicate?

No! You cannot tell the kind of mold by color but rather by structure and characteristics of the spores and growth structure. The color indicates nothing about health risks and exposure.

A Few Simple Facts About Mold and Its Color

Molds can be black, grey, green, brown, purple, pink, orange, white, red, or even a combination of colors. Know that the same mold can be of different colors in different conditions and can change over time. Mold color is irrelevant in determining the toxicity of the mold and you should pay attention to all molds regardless of the color.


When you spot mold, check out the situation before you make any irrational decisions. You can then call a professional because you do not want the mold to be around for longer than it needs to be.
