Cladosporium is an outdoor fungus that is dangerous mold and can enter homes through open windows, doors, and vents. It grows in damp, humid spaces and thrives in temperatures between 70 and 90 degrees.

It is usually found in homes with high humidity levels, poor air circulation, and leaky plumbing. Cladosporium can cause respiratory problems, especially in those with weakened immune systems.

Without proper ventilation, Cladosporium can populate in a home quickly. It can take on various forms but typically shows up as a powdery or cobweb-like substance.


Penicillium can also grow in damp bath walls and tiles, leaky basements, and even in cellars where moist objects such as fruits and vegetables have been stored for long periods.

All of these conditions offer an ideal breeding ground for this type of mold. Although the presence of penicillium should be taken seriously, it is typically not considered an immediate health hazard in most cases.

Removing the source of moisture and dampness is the best way to stop the growth of penicillium in the home environment.


Alternaria is a type of mold known to be also commonly found indoors in homes. It is a saprophytic mold that typically grows on damp surfaces such as walls, ceilings, and furniture. It is a dark-colored mold with a characteristic musty scent.

This mold is widely known to cause allergic reactions in humans, the most common being asthma attacks, hay fever, and sinus infections. It is also known to cause skin and eye irritation.

If found indoors, it should be removed as soon as possible to reduce exposure to allergens and harmful toxins.

The best way to prevent Alternaria from growing in homes is to eliminate sources of moisture, such as damp walls and furniture, and to ensure proper ventilation.


Aspergillus is a fungus that belongs to the Ascomycetes family and grows in a variety of habitats, such as moist environments, high levels of dust, and materials with a high starch content, like ceiling tiles and carpet.

It can also easily colonize and spread in concealed areas, and if not taken care of, it can cause various health problems.

Therefore, it is important to promptly identify and remove mold spores and take preventive measures to keep them from reoccurring.

To learn more, educate yourself on preventative measures and contact a mold testing and removal company to help you with more advice.
