What Is Aspergillus Mold?

Aspergillus Mold

Aspergillus mold is the most common type of fungus on earth that grows both outdoors and indoors. First identified in 1729, there are now more than 200 confirmed species of Aspergillus mold. However, only three of those species known to thrive in indoor environments like homes and commercial buildings: Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus.

Where Does It Grow?

Aspergillus mold is a resilient fungus that grows in temperature ranging from 68 degrees up to over 100 degrees, well within the residential range. Moisture from routine indoor sources such as elevated humidity and minor household leaks—or incidents like water damage—plus a food supply such as paper, fabric, or wood building materials, create optimum conditions that support Aspergillus mold growth.

How Does It Spread?

Within 48 hours after contact with water, active mold growth begins releasing microscopic airborne reproductive spores. These spores are carried by air currents throughout the house, spreading contamination to multiple areas inside the structure. Prompt application of professional preventive methods following water damage is critical to prevent widespread mold infection. 

What Does It Look Like?

Contamination may appear as the “black mold” type, or it may look blue-green, gray, or tan, resembling other fungus varieties. This variation in color is a good reason why all mold contamination inside a home needs to be examined and tested by qualified mold remediation specialists.

What To Do About It?

Aspergillus mold requires professional mold remediation. This includes identifying the exact type with air sampling and tracking contamination within the house. All growth must be physically removed, followed by sterilization of surfaces where it was present with EPA-approved biocides.

Chronic moisture conditions inside the house that triggered the growth of mold must be identified and corrected. After the remediation procedure, follow-up air samples are utilized to verify that contamination has been  eliminated.
