Understanding the Main Categories of Mold

Before diving into the specific types of mold, it is important to understand the different categories of molds found in homes and how to identify and remove them effectively. The following is a list of common categories of molds and a brief description of each category.

Allergenic mold: These types of molds, such as Aspergillus and Penicillium, can cause allergic reactions in some individuals, such as sneezing, runny nose, and red eyes. They are often found in damp or water-damaged areas.

Pathogenic mold: These types of molds, such as Fusarium and Acremonium, can cause infections and other health problems in people with compromised immune systems.

Toxigenic mold: This type of toxic mold, such as Stachybotrys (or black mold) and Chaetomium, produce mycotoxins, toxic substances that pose serious health hazards. They are commonly found in areas with high humidity levels and poor ventilation.

Indoor/Outdoor Mold: These types of molds, such as Cladosporium and Alternaria, are common in outdoor and indoor environments. They can grow on various surfaces and are commonly found in areas with high humidity and poor ventilation.

It is important to note that this is not an exhaustive list, and each home is unique. Therefore, it’s crucial to have a professional inspection to identify the specific types of molds present in your home and provide appropriate treatment.

5 Common Molds Found in Your Home

It’s important to thoroughly understand the various types of mold that can commonly be found in homes. This knowledge can help you identify the specific types of mold present in a home and subsequently determine the most effective method of removal.

These different types of mold can often be identified by their characteristic colors, including black, olive green or dark green, blue, gray, and white, and their distinctive musty or earthy smell.

Below you will find more information on the most common types of molds found in homes, how to identify them, and what your next steps should be if they are found.

Aspergillus:

Aspergillus is a mold found in damp or water-damaged areas with a moisture problem, such as bathrooms, kitchens, and basements, or on damp clothing, paper, and food. It is usually a green or brown color. Prolonged exposure to Aspergillus can cause health problems for some individuals, particularly those with compromised immune systems or respiratory issues. Symptoms can include allergic reactions such as sneezing, runny nose, red eyes, and more serious respiratory issues such as asthma and lung infections.

Cladosporium:

Similarly to Aspergillus, Cladosporium is a type of mold that is also found in homes in areas with high humidity levels. It is typically black or green and can appear as a powdery substance. It can grow on various surfaces, including wooden surfaces, wallpaper, and painted surfaces. Long-term exposure to Cladosporium can cause allergic reactions in some individuals, such as sneezing, runny nose, and red eyes. It can also aggravate asthma symptoms and lead to other respiratory issues.

In addition, Cladosporium can cause damage to the surfaces it grows on, making it important to address it as soon as it is identified.

Stachybotrys:

This type of mold is also known as “black mold” and can be found in homes, particularly in areas with high humidity levels and poor ventilation. It is typically black or greenish-black and can appear slimy or damp. It is commonly found in bathrooms, basements, attics, and around window frames.

This toxic black mold produces mycotoxins, harmful compounds that can cause health issues if inhaled. Exposure to toxic mold can have serious health effects, particularly for individuals with weakened immune systems or respiratory problems. Symptoms can include headaches, fatigue, sneezing, runny nose, and aggravation of asthma symptoms. In extreme cases, it can lead to more severe problems, such as neurological symptoms and respiratory system damage.

Penicillium:

This mold is often found in damp areas or areas that have experienced water damage. It can be found on various surfaces, including wallpaper, carpet, and insulation. It typically appears as a powdery blue or green substance with a musty odor.

Exposure to Penicillium can cause allergic reactions in some individuals, such as sneezing, runny nose, and red eyes. In certain cases, it can also aggravate asthma symptoms and lead to other respiratory issues.

Fusarium:

This mold can be found in homes, particularly in areas with high humidity or water-damaged buildings. It can be found on various surfaces, including carpet, wallpaper, and insulation. It typically appears as a white, pink, or yellow powdery substance and can have a musty smell. Exposure to Fusarium can cause allergic reactions, nail infections, and skin infections if it comes into contact with the skin.

So you’ve got a mold problem. Now what?

Now that you can identify various types of mold, what do you do?

At the first sign of mold infestation, it is crucial to treat it promptly as mold spores rapidly spread and pose a severe health hazard. In addition to health concerns, it can also lead to structural damage to your home. Whether you DIY or enlist the help of a professional, it is imperative to take action as soon as mold is detected.
