At What Temperature Does Mold Grow?

Mold does not just grow during the hot summer months, contrary to popular belief. The way mold grows is strongly influenced by temperature, but this isn’t just a seasonal issue. If the conditions are favorable, mold can grow all year round.

Everyone knows that mold has a terrible smell, it’s unattractive and even dangerous to your health. Knowing where to look during the various seasons of the year can help you remove the threat of mold before it causes a disaster.

In this article, we’ll look at the connection between mold, climate, and temperature.

 

Mold cannot grow at temperatures below forty degrees Fahrenheit in most cases. As a result, many refrigerator settings are set at 39 degrees Fahrenheit. Mold grows best in temperatures ranging from 77 to 86 degrees Fahrenheit, especially when there is a lot of humidity in the air.

To successfully eliminate mold spores, temperatures must rise beyond 100 degrees or fall below freezing.

 

Food Sources

 

Mold will develop on materials or in places where it can digest organic substances if it has the right food source. This makes it tough to get rid of mold in a home since there are dead skin cells, dust, and other tiny particles that can feed a mold colony.

It does require water and oxygen, albeit only a small amount of oxygen is required to keep it alive. Mold is often discovered in basements, attics, cupboards under sinks, HVAC ducts, and bathrooms because of these conditions. Professional mold testing and remediators will perform air quality testing on the interior and exterior for a baseline.

Mold Growth in the Winter

Essentially, mold can still develop in the winter if there is enough moisture in the air, a sufficient food source, and the correct temperature. Mold comes in a variety of forms, and depending on which mold species is growing, it may be more adapted to freezing temperatures.

 

Even though many fungi have minimum requirements, these comfortable conditions generally correlate to the temperatures that the average home maintains throughout the year. If your thermostat is set between 60- and 80-degrees Fahrenheit, you’re fostering a mold-friendly environment.

 

Throughout the winter, not all portions of the United States experience below-freezing temperatures. This makes it difficult to eradicate mold spores completely. Extreme changes in the winter, especially when temperatures drop below 32 degrees Fahrenheit, are harmful to spores, although they may not die and can wait for the house to warm up or the warmer months to arrive before emerging from hibernation.

 

When it comes to mold, temperature alone isn’t enough. You must also address the source of the mold and take preventative steps.

 

Mold Growth in the Summer

 

The growth of mold is often faster during the summer months due to the warmer temperatures. Thus, not only is the air warmer, but the possibility of colony expansion is also increased by more rain and a higher humidity.

Very few places in the United States see temperatures that are over the minimum required to suffocate and kill growth, leaving many people vulnerable to an infestation.

We hope this article has provided you with a good understanding of how mold is influenced by the environment’s temperature!
