What Is Black Mold?

Some people believe that black mold exposure is a serious health concern. However, no conclusive research suggests that exposure to this type of mold causes conditions such as cancer or lung disease.



Mold is a type of fungus. It is present almost everywhere, including in the air. In general, normal amounts of mold in the environment do not pose a substantial health risk to healthy people with regular immune system function.

There is no single type of mold called “black mold” — many molds are black. When people use the term, they may be referring to a type called Stachybotrys chartarum (S. chartarum), also known as Stachybotrys atra.

The Centers for Disease Control and Prevention (CDC) state that a person does not need to identifyTrusted Source which type of mold is growing in their home or another building.

However, some people may be more sensitive to mold spores than others, and they may develop respiratory symptoms after inhaling even a small number of spores. In large quantities, mold spores can cause ill health in almost anyone.

Therefore, people should remove any mold growth in the home and take steps to prevent it from growing back.

Understanding Mold

When water intrudes into your property, mold growth can start in as little as 48 hours. Consider the following mold facts:

  • Mold is present almost everywhere, indoors and outdoors.
  • Mold spores are microscopic, float along in the air, and may enter your home through windows, doors, or AC/heating systems or even hitch a ride indoors on your clothing or a pet.
  • Mold spores thrive on moisture. Mold spores can quickly grow into colonies when exposed to water. These colonies may produce allergens and irritants.
  • Before mold remediation can begin, any sources of water or moisture must be addressed. Otherwise the mold may return.
  • Mold often produces a strong, musty odor, and that odor can lead you to possible mold problem areas.
  • Even higher-than-normal indoor humidity can support mold growth. Keep indoor humidity below 45 percent.
