Toxic Black Mold: The Truth & What To Do

“Toxic Black Mold” May Sound Scary, But the Truth May Surprise You

So, what exactly is “Toxic” Black Mold?

Commonly referred to as black mold, the term “toxic” black mold is often used interchangeably with Stachybotrys Chartarum. This particular mold variety, known for its ominous black appearance, has gained widespread recognition due to its propensity to thrive in residential environments and pose potential hazards to human health. The peril lies in its production of mycotoxins, which are toxins known to be harmful.

The heightened awareness of black mold, fueled by media sensationalism, has instilled fear among homeowners and renters. The portrayal of this mold as a more ominous and perilous form has contributed to its reputation as a formidable health threat. However, it is crucial to acknowledge that mold, in various forms, is ubiquitous, existing virtually everywhere in our surroundings. When mold is visible, regardless of its type, it should be treated with the same urgency and diligence as any other mold—prompt removal and remediation are essential steps to ensure a safe and healthy indoor environment. Understanding that proper action is needed can empower individuals to address mold issues effectively and dispel unwarranted fears associated with the presence of “toxic” black mold.

According to the CDC, the term “toxic” is very misleading. Though there are molds that produce toxins (like mycotoxins), the mold itself is not toxic or hazardous:“Hazards presented by molds that may produce mycotoxins should be considered the same as other common molds which can grow in your house. There is always a little mold everywhere – in the air and on many surfaces. There are very few reports that toxigenic molds found inside homes can cause unique or rare health conditions such as pulmonary hemorrhage or memory loss. These case reports are rare, and a causal link between the presence of the toxigenic mold and these conditions has not been proven.”

Where Does Black Mold Grow?

Like other molds, both toxic and not, black mold will grow and spread in damp, humid areas like basements and crawl spaces. Identifying black mold early could prevent not only health problems, but structural issues that may arise as the mold grows. It is important to find the source of the moisture and dry it completely, especially in the case of broken pipes in walls or particularly wet areas, to prevent future mold growth.

Damp Basements and Crawl Spaces

Black mold thrives in dark, damp environments, making basements and crawl spaces particularly susceptible. Poor ventilation and moisture buildup in these areas create an ideal breeding ground for Stachybotrys Chartarum.

Kitchen & Bathroom

High humidity levels and frequent water exposure in bathrooms create conditions conducive to black mold growth. Mold can often be found on shower curtains, in tile grout, and around sinks and bathtubs where moisture tends to accumulate. Leaky pipes, poor ventilation, and moisture from cooking activities can contribute to the development of black mold in kitchens. Areas around sinks, dishwashers, and under refrigerators are common locations for mold growth.


Inadequate ventilation and roof leaks can lead to moisture accumulation in attics, providing an environment where black mold can flourish. Insufficient insulation and poor airflow exacerbate the risk of mold growth in these spaces.

Closets and Storage Areas:

Cluttered and poorly ventilated closets or storage areas are susceptible to black mold growth, especially if items are stored without proper air circulation. Mold can develop on clothing, cardboard boxes, and other porous materials in these confined spaces.

It’s important to note that these locations are not exclusive, and black mold can potentially develop in any area with the right combination of moisture, darkness, and poor ventilation. Regular inspection and prompt remediation of water leaks or dampness are crucial for preventing black mold infestations in homes.

Cleaning & Keeping Your Home Mold-Free

Though Toxic Black mold sounds like more than you can handle, it should be treated just like any other mold.

Cleaning with Mold-Killing Solutions

Thoroughly clean and scrub non-porous surfaces to eliminate visible mold:

  • Utilize straightforward solutions such as soap and water, cleaning products, or a bleach solution (1 cup bleach to 1 gallon of water) for mold cleanup.
  • Avoid the mixing of cleaning solutions, as this can lead to the production of toxic fumes, such as ammonia.
  • Wear protective eyewear and non-porous gloves when cleaning the affected area to minimize direct contact with mold and cleaning agents.

After cleaning, ensure the treated area is thoroughly dry, and address and fix the source of moisture to prevent future mold growth.

Mold Remediation by Professionals

In cases of extensive black mold infestations or when dealing with larger areas, it is advisable to seek professional mold remediation services. Certified specialists have the expertise and equipment to safely and effectively handle mold problems, ensuring thorough cleanup and preventing future growth.

Addressing Underlying Moisture Issues

Identify and resolve the source of moisture that facilitated mold growth. Repair leaks, improve ventilation, and reduce humidity levels to eliminate the conditions favorable for mold development. Addressing the root cause is essential for long-term prevention.
