While all mold is unsightly and generally unwelcome in the home, not every variety causes health problems. There are several species, however, that are especially harmful. Identifying these organisms usually requires professional mold testing, but you may be able to spot strains that grow out in the open. Review the list below to know what signs to look for and when it’s time to call a mold removal specialist. 

Top 5 Household Microorganisms Requiring Mold Testing 

1. Stachybotrys 

Also known as “black mold,” Stachybotrys is a toxic substance that causes several medical issues. Adults and children may suffer from allergic reactions, neurological illnesses, and depression after exposure. It has a black or dark green color and an oozing texture. Homeowners often find it on walls, floors, and ceilings. 

2. Cladosporium

Cladosporium is green or brown and quite resilient; it can grow during every season of the year. You may spot it on fabric materials like carpet and furniture. Some families may see it growing inside their kitchen or bathroom cabinets. Symptoms of exposure include asthma, skin rashes, and sinus problems.

3. Aspergillus

Aspergillus is another common growth requiring mold testing by an expert. Since it comes in over 180 varieties, it presents itself in nearly every color. Homeowners can distinguish it from other types of mold because of its elongated spores. It often grows on rotting fruit and vegetables, but may also be found in damp attics or garages. Most kinds cause respiratory reactions like asthma attacks and lung discomfort. However, other types can produce deadly carcinogens known as aflatoxins.

4. Mucor

Mucor is a grey or white mold that grows fast and thick in moisture-rich areas. It often develops near air ducts or HVAC systems, but it can also appear after you suffer water damage to your furniture or carpets. The risks of becoming exposed to mucor include damage to the brain, lungs, and sinuses. If you find this substance, call an expert for a mold inspection.

5. Trichoderma 

There are five different types of Trichoderma. It is recognizable by its white and green color. Like mucor, homeowners usually find it around their air conditioner or indoor ducts. It is also often present on wet walls and carpet. If it continues to grow for extended periods, it can cause respiratory and liver infections.
