3 Worst Types of Mold

Posted in Blog | Mold Inspection on June 21st, 2017 by Hunter Adams

Finding mold in your home is a scary experience, especially when it’s black mold. But, did you know there are several types of toxic molds that should be avoided at all costs? Here are just a few of the worst.


Chaetomium molds are usually found in water-damaged structures, but they can also make their way into baseboards, drywall, window frames, and carpets. What makes chaetomium dangerous is that it produces elevated levels of mycotoxins, which can result in allergic reactions, skin infections, and in worst-case scenarios, neurological damage.

This type of mold produces the characteristic musty odor that is easy to identify. If you suspect chaetomium, have your home inspected for mold right away. Prevent the mold altogether by tackling any water issues before they can cause damage.


Like chaetomium, fusarium thrives in damp environments. You might spot it in your humidifier reservoir or along damp wallboards. While fusarium isn’t necessarily as toxic as chaetomium, certain people are susceptible to eye diseases caused by this type of mold, including fusarium keratitis. Fusarium can also cause pneumonia in immunocompromised individuals.

Fusarium is difficult to identify. Only the most experienced professionals can trace its presence.

Stachybotrys Chartarum

Also known as “black mold,” stachybotrys chartarum has earned a reputation as being one of the most toxic indoor molds you can encounter, and rightly so. While the mold itself isn’t toxic, stachybotrys chartarum releases mycotoxins that cause health issues, including breathing problems, allergies, asthma attacks, sinus infections, depression, and fatigue.

Maintaining a clean, dry indoor environment will prevent black mold from growing. If you already have black mold, have it professionally removed and monitored.
