What Is Black Mold?

Black mold, or what scientists call Stachybotrys chartarum, has a bit of a notorious rep. Black mold isn’t your ordinary household guest.

It is a type of fungus that thrives in moist, damp environments. It stands out for its dark green to black color and often looks slimy and wet. Black mold grows on things like wood, paper, and drywall when they get too wet from leaks, floods, or high humidity.

This mold is concerning because it can produce mycotoxins and mycotoxins are harmful substances that can seriously impact the health of people and pets in the home. They can contaminate food, air, and surfaces, making them particularly dangerous. Exposures can also result in symptoms ranging from mild allergic reactions to more severe conditions such as respiratory issues, immune system suppression, and even neurological damage. 

Common Breeding Grounds for Black Mold

Here’s a brief overview to keep in mind:

  • Black mold gravitates towards moist conditions. Typical locations for mold growth include bathrooms, windows, under sinks, attics, and AC units.
  • Areas with water damage or ongoing dampness are particularly vulnerable.
  • They grow on areas where there’s a source of food, this includes, organic materials such as wood, drywall, or paper.

So, What Does Black Mold It Look Like?

Like it was mentioned above; black mold typically appears as dark greenish-black patches or spots on surfaces. It may have a slimy or fuzzy texture, depending on its age and environmental conditions.

They looks dark greenish-black because of its pigment, melanin, which helps protect it from UV radiation and aids in its survival. Its slimy or fuzzy texture is due to the growth of spores and mycelium, which can vary depending on its stage of growth and the surrounding environment.

Health Problems From Black Mold Exposure:

Black mold and its toxins can affect health in various ways. The impact depends on the level of exposure and individual sensitivity. Some people may only experience mild symptoms. Others could face serious health issues if they come into contact with black mold.

Below are common symptoms people who are sensitive to mold would experience.

  • Allergic Reactions: Common symptoms include sneezing, itching, runny nose, red eyes, and skin rash. People with mold allergies may have more severe reactions.
  • Respiratory Problems: Exposure to black mold spores can cause coughing, wheezing, difficulty breathing, and exacerbation of asthma in susceptible individuals.
  • Irritation: Mold exposure can irritate the eyes, skin, nose, throat, and lungs, even in people who aren’t allergic to it.
  • Immune System Suppression: Prolonged exposure can suppress the immune system, making the body more susceptible to other infections.
  • Mycotoxicosis: Certain molds produce mycotoxins that can lead to mycotoxicosis, or mold poisoning, with symptoms ranging from acute discomfort to long-term health issues like memory loss, sensitivity to light, headaches, and mood changes.

Keeping your home mold-free requires proactive measures to eliminate moisture sources and create an inhospitable environment for mold growth. Dust and vacuum regularly could help you prevent the buildup of organic matter that mold feeds on. Ensure good airflow throughout your home by opening windows and using fans to reduce humidity. And most importantly, address any leaks or water damage promptly to prevent moisture buildup and mold growth.

Tips for Humidity and Moisture Control:

  • Utilize dehumidifiers to maintain optimal indoor humidity levels, ideally between 30-50%
  • Ensure proper ventilation in bathrooms, kitchens, and other areas prone to moisture buildup
  • Regularly inspect and repair any leaks in plumbing, roofs, or windows to prevent water intrusion
  • Use exhaust fans during and after activities that generate moisture, such as cooking or showering
  • Consider installing moisture-resistant materials in high-risk areas, such as moisture-resistant drywall or flooring.


We often wonder if black mold dies when it dries out. Drying out can slow mold growth. However, black mold spores can stay inactive. They may start growing again when moisture returns.

Preventing Black Mold Growth

Identifying black mold in its early stages not only protects your health but also saves you from potential expenses on home repairs and medical bills. By addressing mold issues promptly, you’re investing in the longevity of your home and the well-being of your family.

How to tell if you have black mold in your house?

Mold on walls typically appears as fuzzy patches or discolored spots. It can vary in color, ranging from green and black to white or orange, depending on the type of mold and the surface it’s growing on.


Identifying black mold in your house can be tricky since not all black molds are toxic, and not all toxic molds are black; Stachybotrys chartarum, commonly known as black mold, is one of the more concerning types. It typically appears slimy and dark green to black in color. If you see visible mold then there’s no guessing, however, most people will experience unexplained and consistent symptoms like those mentioned above (respiratory issues, skin irritation, headaches, and allergic reactions).

What kills black mold instantly?

When it comes to eliminating black mold, there’s no instant solution. However, several methods can help mitigate its growth and remove existing colonies. One effective approach is to use a mixture of water and detergent to scrub the affected area thoroughly. For more stubborn mold, a solution of vinegar or hydrogen peroxide can be effective.

However, the best method is a mold inspection by a professional mold inspection company like Reagan Environmental. A mold inspection & testing will help us to pin point the source of moisture, identity the spores level per squared footage and will help us at Reagan Environmental create plans on how to remove black mold from your home.
