4 Most Dangerous Types of Mold Growing in Indoor Environments

4 Most Dangerous Types of Mold Growing in Indoor Environments - Bio-One of Oceanside.

Controlling the humidity and moisture levels inside the house or property is the most efficient way to prevent mold from growing and causing problems to our health and the deterioration of our home. Bio-One of Oceanside, a  Micro Certified Mold Remediation Contractor, shares the four most dangerous Molds that grow in Indoor Environments and how our mold cleanup and remediation specialists can help you remove and remediate your house or property from them.

Mold is very common in outdoor and indoor environments. Outdoors, mold is part of the natural ecosystem, as it helps decompose dead organic matter (e.g., leaves, dead trees, animals), so we’re always in the presence of mold. 

Now, while mold is inevitably present in indoor environments, the impact that it will have on your health will depend on how mold is controlled. Mold needs water or moisture to grow and disseminate, so it’s important to promptly fix any water-related issues like leaky pipes and leaks on the roofs, windows, and other areas in your house or property.

Stachybotrys Chartarum - Also known as “black mold”

Stachybotrys chartarum is commonly known as “black mold,” and it’s one of the most dangerous and common types of mold in indoor environments. This type of mold can grow in organic materials like fiberboard, carton board, gypsum board, wallpaper, and others. 

The combination of moisture and these organic materials makes up the perfect place for mold to grow quickly and disseminate. Mold feeds from the surface where it’s growing to the point of consuming it. This represents a structural safety risk for your house or property. Bio-One of Oceanside's mold cleanup and remediation technicians have assisted properties where the foundations have experienced deterioration from mold damage, so you must attack mold from the moment you see signs of damage.

Stachybotrys chartarum can also have severe health repercussions, especially for people suffering from pre-existing conditions. Continuous “black mold” exposure can cause diarrhea, flu-like symptoms (runny nose, sneezing, and coughing), and other respiratory problems.

Bio-One of Oceanside's specialists can help you assess the level of damage in your house and property and, using EPA-approved chemicals, follow strict guidelines to remediate areas impacted by mold.

Aspergillus - The cause of Aspergillosis Infection

Aspergillus is another type of mold present in both outdoor and indoor environments. It’s common for people to breathe Aspergillus spores daily, so it’s not considered a threat to humans. However, when Aspergillus spores concentrate in small, dark, indoor environments, they can cause respiratory problems for people with pre-existing medical conditions. 

Aspergillus is the cause of Aspergillosis, an infection that affects people with a weakened immune system. Aspergillosis infection signs include constant allergies, lung infection (which translates into difficulty breathing), and infection in other body parts. There are multiple types of Aspergillosis, each affecting the body differently.

Bio-One of Oceanside's mold cleanup and remediation technicians are professionally trained to clean areas from mold damage. Our technicians evaluate the area with special equipment to guarantee a successful removal of mold in your house or property. 

Penicillium - Dangerous if concentrated indoors


Like Aspergillus, this type of mold is very common in outdoor and indoor environments. Penicillium plays an important role in the natural environment outdoors, as it’s responsible for processes like food spoilage. In an indoor environment, however, represents a high risk of allergy and other pathologies, and spores can easily travel through the air and contaminate poorly stored food and other household supplies. 

Penicillium is particularly difficult to address indoors because it only requires a minimum humidity level to grow. Like most types of mold, it will feed and consume the organic matter from where it’s growing, and it can have repercussions on people struggling with allergies and other respiratory problems.

The mold cleanup and remediation process should be done by Professionals. Inadequate mold remediation can lead to more severe health problems and complete damage to building structures and items. Bio-One of Oceanside is a Micro Cerfified Mold Remediation Contractor. Our specialists can dispose of any items infested with mold, guaranteeing a safe, hazard-free environment.

Chaetomium - Triggered by water damage and dampness,

Chaetomium is similar to Stachybotrys chartarum because they both can fit into the “black mold” category because they share the same conditions to grow. It's very common in damp areas and areas where there’s water damage. 

Like most types of mold, Chaetomium is disseminated through spores that travel in the air, quickly growing in organic matter with moisture, like drywall, paperboard, carpet, and flooring. 

Chaetomium mold has a distinctive blackish appearance, similar to Stachybotrys chartarum, and the smell is very musty. If your house or property has experienced water damage from flooding, leaks, or broken plumbing, it’s important to remove and take out any items that might be moist (like carpets or furniture). 

If you see any signs of black mold growing on your walls, floor, or other areas, do not hesitate to call a professional. Mold is very persistent; sometimes, it can grow in the darkest and most complex areas. Bio-One of Oceanside's mold cleanup and remediation technicians will make sure to thoroughly inspect your house or property to remediate areas that might be present.
