What Temperature Does House Mold Grow?

Does temperature affect mold growth?

Temperature also affects mold growth.

Many fungi grow well at temperatures between 60 and 80 degrees Fahrenheit, which are also ideal temperatures for human comfort.

In addition, as mentioned above, temperature gradients often produce the moisture needed for mold growth..

What humidity grows mold?

Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent — ideally between 30 percent and 50 percent, if possible. Low humidity may also discourage pests (such as cockroaches) and dust mites.

Does cold weather kill mold?

However, cold weather–even freezing temperatures–will not kill mold spores. Instead, mold spores will lie “dormant” until moisture and warmth make growth possible again.

Does sunlight kill mold?

Ultraviolet (UV) light from the sun kills most mold and spores, which is why you don’t see it growing outside in the open. … Those are the ones that need to be kept dry and free from mold food sources more than areas that get natural sunlight.

What temperature should you keep your house to prevent mold?

The ideal temperature is between 77 and 86 degrees Fahrenheit. During the summer months, temperatures are often higher than normal inside the home. Make an effort to keep temperatures inside the home lower during the summer months. Setting the thermostat to the low 70s makes it more difficult for mold to grow.

At what temperature do mold spores die?

Most yeasts and molds are heat-sensitive and destroyed by heat treatments at temperatures of 140-160°F (60-71°C). Some molds make heat-resistant spores, however, and can survive heat treatments in pickled vegetable products. These molds, however, require oxygen to grow.

Can mold grow at 40 degrees?

Molds typically grow at temperatures ranging from about 40 degrees to 100 degrees Fahrenheit. Therefore, the temperature in our homes is usually adequate for mold growth. Of course, most places in our homes have an adequate oxygen supply for mold growth.

Why does mold not grow in cold temperatures?

Cold weather will not kill mold. … Even when temperatures drop below freezing, mold spores don’t die; they simply become dormant and will begin to multiply and grow again as soon as the temperature rises. That’s why controlling the temperature alone will not solve your mold problems.

Will a dehumidifier kill mold?

Mold stays “dormant” in the air or on surfaces even when there’s no excess moisture to help it grow. … So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity. If you have a mold problem in your home, don’t wait. Mold spreads as long as it has a water source.

Is mold worse in summer or winter?

The dry air in the winter months typically suppresses mold, because fungal spores need food and water to grow. This time of year, mold spores are typically not as prevalent as they are in the summer months, since mold can’t grow in freezing temperatures.

Will mold die if it dries out?

Mold spores become inactive temporarily after they have dried out but can remain a threat as long as they are present in the environment. … Without constant moisture, mold will become inactive but they never die unless you get rid of them completely.

Can a hair dryer kill mold?

To kill mold, you must eliminate the moisture available to it. … Resist the temptation to use a hair dryer or fan; they will blow mold spores around, increasing the chance that a new colony will sprout. After you’ve dried up the mold, clean it up with soapy water.
