Continue reading to explore more about these potential risks.

What Is Black Mold?

What everyone calls mold is a type of fungus. There are 60 types of molds that can be black and the black mold that makes people sick is known as Stachybotrys chartarum.

Where and How It Grows

This fungus are growing on materials that contain a lot of cellulose. Such materials can include drywall, wood products, and paper products.

However, black mold doesn't develop in these areas on its own. It needs warmth and moisture to grow and spread. This is why it often appears in water-damaged areas or ones with high humidity (like your attic).

Can Black Mold Hurt Humans?

Yes, black mold exposure can cause health issues in humans. However, it's important to note that not everyone is equally affected by black mold. Those who have fungus allergies or related health conditions may be more susceptible to developing issues from exposure to black mold.

Also, many black molds create by-products called "mycotoxins". Experts have found that these are toxic to humans. This often causes health issues as well.

  • Fatigue
