Alternaria is one of the most common types of outdoor mold. There are more than 40 known species of it and it is often responsible for leaf spots and degenerative diseases on trees and bushes. A major plant pathogen, it is most commonly found in the environment in spring and summer.

The Characteristics Of Alternaria Mold

Alternaria mold lingers in the air on dry, windy days. When picked up by a breeze, it can become airborne and enter your home, looking for a warm and humid place to multiply. If it gets in, it can attach to anything, and like other types of mold it can also live and grow in hard to find places, like under carpets and inside walls. Humid homes are especially susceptible to this type of fungi growth, which may reach tens of thousands of spores per cubic foot. It is dark in color and has a downy or woolly texture.

What Are The Health Risks Of Alternaria Mold?

Alternaria can cause a variety of health problems for you and your family, with symptoms ranging from a runny nose, cough, and sore throat to itchy and irritated eyes, wheezing, difficulty breathing, and shortness of breath. Hives and rashes on the skin are also possible. People with asthma are particularly susceptible to illness caused by Alternaria. Also, families with infants should be especially cautious—babies who breathe in toxic spores can experience all of the respiratory-related symptoms above and are also at an increased risk of SIDS and crib death.

How to Prevent Alternaria Mold From Getting In Your Home

During summer, keep all entryways closed especially when it is hot, windy, and dry, and reseal drafty doors or windows and fix breaches in your roof. Repairing or installing new rain gutters can also help direct mold-causing moisture away from your foundation. As with any mold, it’s important to check for leaks regularly and reduce the humidity level inside the house by keeping your HVAC system running or using a dehumidifier. Getting your home’s air ducts cleaned periodically and insulate your house if it needs it.
