Newsflash: mold is everywhere! And untreated mold is a very common household problem. All mold is not the same, and some types of household mold can be more harmful than others. Read on to learn more about common types of mold found in homes.

Household Mold – Common Culprits


Aspergillus mold is pretty much unavoidable. Outside, it grows on plants, trees, and compost. Inside, it can live on food, dust, and in HVAC systems. Aspergillus doesn’t bother healthy people, but it can create problems for those with weakened immune systems. It may cause reactions such as inflammation of the lungs as well as respiratory infections.


Penicillium is a common mold that grows on wallpaper, wallpaper glue, and fabric in water-damaged buildings or homes. This common household mold causes allergies, hay fever, and asthma. This type of mold can spread easily and quickly move from one area of your home to another. Penicillium usually appears as a blue or green mold.


Although Cladosporium is an outdoor fungus, it can easily come into your home through your HVAC system. There is also a species of Cladosporium that grows on fabrics, wood and in any damp areas of the home. Cladosporium can also grow on surfaces that experience condensation, especially around windows and a/c supply vents. Cladosporium is recognized as a black or green “pepper-like” substance.

Stachybotrys Chartarum

Also called black mold, Stachybotrys chartarum has a musty odor and can normally be found in places that stay damp all the time, such as air conditioning ducts or areas around leaky pipes. This mold appears to be slimy and produces mycotoxins that may cause serious health problems.
