Knowing the different types of mold in your home is key to identifying them early on. You can hire a company to conduct mold testing in Clive, IA, or anywhere you live, to identify the mold in your home. If you identify it early, you can prevent it from spreading. This helps reduce damage more efficiently.

Here are some of the prevalent signs of mold you should know about. Keep on reading to know more about mold-related health issues and the different types of mold found in homes.


Mold can be found in homes for many different reasons. Most commonly, mold grows due to moisture and dust in the home. Mold can cause a variety of health problems and should be addressed as soon as possible.

Aspergillus is one of the most common types of mold found in homes. It is a type of fungus that typically grows outdoors but can make its way into homes, growing on damp surfaces, such as wallpaper and carpets. Aspergillus produces mycotoxins, which can cause respiratory ailments in humans.

Removing moisture is key to controlling, and eventually eradicating all types of mold in homes. Implementing proper ventilation and regularly cleaning damp or wet areas can help prevent and mitigate the spread of all types of mold, including Aspergillus.


Mold is a type of fungus, and there are many different types found in homes. Cladosporium is one of the most common and is usually found in wet or humid places. It is gray-green or black in color, and it is often found near the floor, in cold climates, or in moist places. It is a common outdoor species of mold that can be found indoors growing on walls, carpets, insulation, and other indoor surfaces.

Cladosporium can also appear on fabrics or food and is often found in areas with poor ventilation or in bathrooms. It is not generally considered harmful but can lead to respiratory issues for those with allergies. To minimize the growth of mold, it is important to maintain adequate ventilation and keep the home free of excess moisture.

Regularly cleaning surfaces and reducing the presence of allergens in the home can also help reduce mold growth. Knowing the types of mold found in the home and taking steps to reduce their presence can help maintain a healthy home environment. 


Mold is a type of fungus that thrives in moist environments with organic matter. In homes, mold can grow in places like bathrooms, basements or attics and generally is seen as a blackish-greenish substance growing on the walls or ceiling. The most common type of mold is Penicillium.

It is often found in damp areas, where mold can quickly spread and can have many adverse health effects on humans. Penicillium is a common mold found in air conditioning systems, wallpapers, furniture, and carpets and can even be found in food. It is a type of mold that can grow in the absence of light and have a musty odor.

The spores from Penicillium can cause severe allergic reactions and asthma in humans. In addition to Penicillium, other common types of mold found in homes include Memnoniella and Stachybotrys. To protect your health and home, it is important to address any mold issues that arise. 


Mold can be found in many places in the home, and can range in color and type. Of the various types of mold found in homes, one of the most dangerous is Stachybotrys. Stachybotrys, or “Black Mold”, is a dark green, black, or blotchy in appearance and is often slimy in texture.

It can produce allergens and mycotoxins and is typically found in damp areas of the home that are not well-ventilated, such as high-humidity bathrooms and kitchen-like areas. The presence of Stachybotrys mold in a home is a serious health concern as it can cause respiratory issues and other symptoms of illness.

To prevent Stachybotrys from growing, it is important to regularly inspect and clean damp areas of the home, including areas underneath sinks and in crawl spaces. The presence of Stachybotrys should be taken very seriously, and immediate action should be taken to remedy the situation. It’s best to contact professionals like the CCA Public Adjusters to help you handle this type of mold removal.


When it comes to the mold found in homes, one type that most people are familiar with is Stemphylium. It is a common indoor allergen, found in more humid and damp climates. It is a thin, thread-like mold that often appears as yellowish spots or patches.

This type of mold loves to grow on paper products, wood, cardboard, and textiles. It also loves dark and damp areas, like surfaces near air conditioners or below sinks. Stemphylium can cause a range of health problems if inhaled, ranging from allergies to asthma attacks.

To avoid this type of mold, keep the home well-ventilated and free of any standing water and moisture. Be sure to check for mold growth periodically and take steps to reduce humidity levels throughout the home.


There are several types of mold found in homes, one of the most common being Alternaria. Alternaria is a type of allergenic mold that thrives in environments that are damp and humid. It is typically found in bathrooms, around windows, and near other water sources.

Alternaria is a dark green or brownish-black color that grows rapidly. It is typically seen in showers and tubs, as well as in basements due to its affinity for moist areas. Because it feeds off organic matter, it can also be found on furniture, carpets, and any other organic material in the house.

It’s important to properly identify and address Alternaria, as it can cause mild to severe health issues such as coughing, itchy eyes, and sneezing.
