What is black mould?

Black mould, also known as Stachybotrys chartarum or Stachybotrys atra, is a type of fungus that can grow in homes and other buildings. It is typically found in areas with high levels of moisture or humidity, such as basements, and bathrooms.

What causes black mould in your home?

Black mould is caused by the presence of excess moisture in a building. This can be the result of leaks, flooding, or poor ventilation. When moisture is allowed to collect on building materials, such as plasterboard, wood, or carpet, it creates the perfect conditions for mould to grow.

What are the dangers of black mould?

The dangers associated with black mould are numerous. Exposure to mould can cause respiratory issues, such as difficulty breathing, coughing, and congestion. It can also irritate the eyes, nose, and throat, and cause headaches and dizziness. In extreme cases, mould exposure can lead to more serious health problems, such as allergies, asthma, and even immune system disorders.

How to remove black mould

If you suspect that your home has black mould, it is important to remove it as quickly and safely as possible. The first step is to identify the source of the moisture and fix it. This may involve repairing leaks, improving ventilation, or installing dehumidifiers.

Once the source of moisture has been addressed, the mould itself can be removed. This should be done carefully, as mould spores can easily spread and cause health problems if inhaled. Wear protective gear, such as gloves, goggles, and a mask, to avoid direct contact with the mould.

To remove the mould, begin by scrubbing the affected area with a solution of water and detergent. This will help to loosen the mould and kill any remaining spores. After scrubbing, use a damp cloth to wipe away the mould and any remaining debris.

Once the mould has been removed, it is important to prevent it from returning. This can be done by controlling moisture levels in the home and regularly cleaning and maintaining the affected area. Be sure to check for leaks and other sources of moisture regularly, and fix any problems as soon as they are discovered.


In conclusion, black mould is a common and potentially dangerous problem in homes and other buildings. It is caused by excess moisture, and can lead to serious health problems if not removed properly. To remove black mould safely, it is important to identify and fix the source of moisture, and then carefully clean the affected area. By taking these steps, you can protect your health and prevent mould from returning in the future
