What is black toxic mold

Toxic black mold, also known as Stachybotrys chartarum, is a very dark black or sometimes dark green mold. It’s a highly toxic type of mold often found in attics and lofts.

What makes black toxic mold harmful

Black toxic mold is hazardous because it releases mycotoxins into the air. Mycotoxins are harmful chemicals that can pose health risks when breathed in by humans.

What causes black toxic mold/mycotoxins

This type of black toxic mold thrives when the material remains damp for at least three days. Inadequate ventilation is a prime factor, as it allows moisture to linger on surfaces and in the air.

For instance, a bathroom without proper ventilation, like a fan or an open window after baths or showers, can create a conducive environment for this mold.

Another example is a bathroom exhaust fan that vents into the attic instead of outside, leading to the buildup of moist, humid air, promoting black toxic mold in the attic.

Flooding or long-standing leaks can also be a cause. The mold requires a food source rich in cellulose and low in nitrogen to grow quickly.

Blocked attic vents can contribute to the issue. If you find a blocked attic vent, remove any mold first, and then promptly repair or replace the vent to completely resolve the problem.

The health risks of black toxic mold

Black toxic mold is not just an aesthetic concern. While non-toxic mold can trigger allergies, exposure to toxic mold can pose serious risks to the respiratory and neurological systems. It can lead to chronic health issues like asthma, persistent headaches, skin rashes, depression, tremors, and in very extreme cases, even death.

It’s absolutely essential for more homeowners, landlords, and tenants to understand how to remove black toxic mold and prevent its development in the first place.

How to eliminate black mold

When dealing with black mold, whether it’s toxic or non-toxic, the choice between home remedies and specialist sprays depends on the severity of the issue. If you have a heavy case, like after tenants didn’t ventilate the property or during a renovation of an old home, professional help is crucial.

The key is to identify and address the root cause of the mold first. 

For severe cases, call in experts as disturbing black toxic mold can release harmful spores. 

If it’s not severe, you can try DIY methods, but always protect yourself during the process, wear protective gear like gloves and a mask.

1. White vinegar. Spray the affected area, wait 15 min, spray again, scrub with a brush, wipe clean with a damp cloth. Vinegar, with its pH of around 2.5 effectively tackles black mold by acting as an antibacterial to break down and kill the mold. You can also combine white vinegar with baking soda in a spray bottle for better results.

2. Hydrogen peroxide or baking soda. These are effective for moderate cases. You can mix 1 part of “3% hydrogen peroxide” or baking soda with 2 parts water in a spray bottle to create a cleaning solution. Spray the infested area, wait 10 min then scrub and rinse thoroughly. Hydrogen peroxide is a natural remedy that serves as an antiviral, antibacterial and antifungal solution. It’s safe for use and doesn’t harm the environment. It’s particularly effective at removing mold from porous materials like woven fabric furniture.

3. Borax. Mix one cup borax + one cup water in a spray bottle. Borax is natural and has antimicrobial quality. Gently scrub the mold with a small brush. Wipe the area with a damp cloth. Dry the area thoroughly with a soft cloth.

4. Commercial mold cleaners. Stronger commercial mold cleaners like HG Mold Remover Foam Spray can be effective for moderate to severe cases. Follow the product’s instructions carefully, and always ensure proper ventilation as it produces strong fumes.

5. Professional mold removal. For severe or extensive mold problems, it’s best to hire a professional mold removal service.Professionals have the expertise and equipment to safely remove the mold and prevent its return.

Remember that the severity of the mold problem, the type of mold (toxic or non-toxic), and the affected area will determine the appropriate treatment method. It’s crucial to address the root cause of the mold to prevent its recurrence, regardless of the treatment used.

How to prevent black mold

After removing black mold, it’s crucial to create an inhospitable environment to keep it from returning. Remember, prevention is key. Your bathroom is the main stage for mold as it’s full of moist air all the time. Without adequate ventilation, this moisture has nowhere to escape, so it lingers on walls and ceilings inviting black mold in. Ensure your air vent or air conditioning is functioning well and effectively reduces moisture. Think about getting a dehumidifier. Also, ensure there’s good airflow throughout your home by opening windows and doors, including internal ones, as much as possible.

Here are some additional steps to prevent mold:

Fix any leaking pipes. Ensure windows are well sealed. Avoid drying wet laundry on radiators without proper ventilation.
Be cautious of rising damp. Quickly dry any wet spots. Consider using mold prevention paint or additives. Purchase a moisture meter (aim for 30%-60% humidity). If you have indoor plants, they improve air quality, but remember that soil and leaves can encourage mold.
Rotate your plants every few weeks to prevent mold.
Regularly inspect your home’s exterior for leaks and clogged gutters.
