What is Aspergillus Mold?

aspergillus-moldAspergillus is quite prevalent and ranges from arctic regions all the way to the tropics.

While not dangerous to most people who have healthy immune systems, those with weak immune systems are more at risk for infections of the lungs or other issues.

When you have the mold removed, it may be best to completely leave the premises and only return when the mold has been completely taken care of.

A Real Danger

Like most molds, aspergillus mold can be very dangerous to humans and animals alike. There are about 16 different species of aspergillus mold that cause diseases and infections. The health effects of the mold can get into a person’s lungs and start to grow. Aspergillus mold is also known to cause hearing problems, up to and including hearing loss.

Types of Aspergillus

Aspergillus Niger is the most common of the aspergillus molds found in nature since it can grow just about anywhere. Most commonly, it is found growing behind damp walls. The mold is black on the surface and white or yellow underneath.

Aspergillus Flavus is another type of mold. This produces carcinogenic mycotoxins, which can contaminate food. The surface of the Aspergillus Flavus is yellow-green and has a red-brown tint on the underneath.

Aspergillus Fumigatus is the most toxic of the aspergillus mold family. People who are exposed to this type of mold can develop hypersensitivity to the mold, causing them to potentially develop a severe allergy to it.

This specific type of mold can be found growing on decomposing organic material. The Aspergillus Fumigatus is a bit different from other molds in that it thrives off colder temperatures than most. The mold can grow in temperature as low as 68 degrees Fahrenheit.

Health Risks

One serious health risk that aspergillus mold can bring on is known as Allergic Bronchopulmonary Aspergillosis. This affects a person’s immune system and can cause a lot of harmful symptoms. It can bring on fever, loss of appetite, malaise, coughing up mucus or blood, wheezing, or even sepsis.

Removing the Mold

Like most molds, the easiest way to get rid of it is to identify its type correctly. Aspergillus mold will generally have a powdery texture, but the colors can differ. The rate at which the mold grows can also be an indication of what type of mold you are dealing with.

Whether you’re able to properly identify the type of mold you or you are unable to, sometimes it’s prudent to get in touch with a specialist who can help with mold removal and remediation.

Where Can Aspergillus Be Found?

These molds thrive in oxygen-rich environments. They feed off the carbon as their nutrients. Some common places you may find aspergillus mold is on compost or fallen leaves since it grown on decaying vegetation.

Aspergillus mold can also be found on living trees and plants. You can also find it right in your own kitchen growing on starch-rich items such as potatoes or bread.

The mold can also be found in dirty air-conditioners. And, like most molds, it often grows on the inside of walls at your home or office, especially if you are dealing with flooding or any type of water damage.
