The worst place for mold to breed in is in the bedrooms because of the time spent in them sleeping, you are at a high risk of exposing yourself to mold, which is dangerous.

How do you know if it’s Black Mold?

First of all, you need to distinguish between mold and mildew. Mold grows above the surface and in circles. Mildew, on the other hand, doesn’t rise above the ground. It grows in a pattern, like an oil spill or dark stain.

Even though they both change colors as they grow, they often exhibit a greenish-black color. Mildew is also easier to remove and is less harmful. Most types of mold can cause health complications, but black mold is a special type that may even release toxic elements. 

Black mould, also known as Stachybotrys, has a distinct smell of a stale, earthy scent of dirt and rotten leaves. It likes more humid areas than the rest and feeds on drywall, cotton, and cardboards, to name a few. Wet or flooded conditions are also ideal for black mould growth.

How Can You Tell The Difference Between Mold And Black Mold?

As mentioned in the previous section, black mold is more harmful than other common molds. It also has a distinct smell of a stale, earthy scent of dirt and rotten leaves. Besides the smell, the only other way to distinguish it from the rest is that it’s black.

Scientifically, there are no mold species known as “black mold”, but studies show that Stachybotrys is the most toxic mold and is what most people refer to as black mold. It exhibits a greenish-black color but can be white or pink depending on where it grows.

Another way to identify the difference between common mold and black mold is the effects on your health. This is the most accurate way. Common mold is less harmful. But if you start experiencing heightened allergies, wood rotting, or other materials in your house discoloring, then you most likely have black mold.

Black mold is the most toxic species of molds. It has adverse effects on your health and to your home. Even though there are simple home remedies, like vinegar, to try removing molds in your home without hiring anyone, this is not an issue you should deal with on your own.

Finding the source of moisture is the key to eradicating the problem once and for all. Leave it to the experts, especially if you cannot pinpoint the source of the problem.

Is vinegar more effective than bleach?

Vinegar is more effective in getting rid of mold off your flooring surface because it is able to penetrate into the membrane and address the main cause of black mold as well as inhibit its recurrence. Bleach on the other hand only cleans the surface mold and doesn’t penetrate into the membrane. As such in many cases, the background mold spores will remain which may reoccur.
