Mold grows faster in the summer months. However, winter doesn’t always mean we are in the clear. Although it does not grow at temperatures below freezing, mold can survive in dormancy and await the coming spring. Mold thrives in moisture, where it grows the quickest.
Does heat make mold worse?
As with cold temperatures, heat will kill mold but only temporarily. The reason many people think high heat kills mold is that the heat usually drys out the moisture. Since it’s the moisture that causes the mold, it appears to die. But as the temperatures return to normal and the water returns, so does the mold.
What time of year is mold worse?
Mold growth is most prevalent from early spring to mid-fall, but its peak is during late summer. Be sure to check for excess moisture on your property during weather and climate changes, such as snow thaw, rain, and humidity. Mold often grows on walls exposed to moisture.
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.
Is mold worse in the summer?
Higher temperatures mean more potential for mold, but there are several ways to fight it. Summertime brings sun and fun, cookouts, vacations — and mold. The risk of mold growth in your home increases in summer months due to several factors like warmer temperatures and summer rains.
Does mold thrive in heat or cold?
Temperature also affects mold growth. Different types of mold have minimum, optimum and maximum temperature ranges for growth. Many fungi grow well at temperatures between 60 and 80 degrees Fahrenheit, which are also ideal temperatures for human comfort.
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.
How can I tell if mold is making me sick?
What Are The Symptoms of Mold Sickness? Wheezing/shortness of breath. Rash. Watery eyes. Runny nose. Itchy eyes. Coughing. Redness of the eyes. Long standing or frequent sinusitis.
How do you tell if there are mold spores in the air?
Some are designed to only determine whether mold is present on surfaces. To test for mold spores in the air you’re breathing, you’ll need to purchase a viable mold test kit, which costs $20 to $45 (view example on Amazon).
What does a mold allergy look like?
What Are the Symptoms of a Mold Allergy? The symptoms of mold allergy are very similar to the symptoms of other allergies, such as sneezing, itching, runny nose, congestion and dry, scaling skin. Mold spores get into your nose and cause hay fever symptoms. They also can reach the lungs and trigger asthma.
How do I keep my house mold free?
How to Stop Mold Growth in House Control moisture. Keep the humidity level under 60 percent. Dry up wet materials quickly. Clean, disinfect, and dry surfaces prone to mold growth. Repair leaks. Dry items thoroughly before storing them. Improve airflow at home. Monitor your basement’s ventilation.
Can keeping your house cold cause mold?
Can mold grow in cold temperatures? The short answer is yes. Mold requires three things to grow: enough moisture, an adequate food source, and the right temperature. Different types of molds thrive under different conditions, and some molds are more likely to grow in the winter months than others.
Can keeping your house too cold cause mold?
Mold growth The colder you keep the indoor air in your home, the colder the walls, ceilings, floors, and windows will be. When water vapor from the air gets into the porous materials in those building assemblies, you have an ideal place to grow mold.
Why is mold high in summer?
Summer is one of the ideal seasons for mold growth due to high levels of humidity. The condition may be worsened further with poor ventilation, which hinders free flow of air. Hot temperatures outside and cold temperatures in the indoors can lead to condensation around windowsills, and other insulation materials.
Can mold grow at 60 humidity?
Water Vapor If there are no cold-condensing surfaces and the relative humidity (RH) is maintained below 60 percent indoors, there will not be enough water in those materials for mold to grow. However, if the RH stays above 70 percent indoors for extended periods of time, mold will almost certainly grow.
What season mold grows?
Mold problems occur in airtight homes more frequently in the warmer months (when humidity is high inside the house, and moisture is trapped), and occur in drafty homes more frequently in the colder months (when warm air escapes from the living area and condenses).
What can mold not grow on?
Mold grows and feeds on organic substances such as wood or cotton. Mold should not grow on surfaces like plastic, metal or glass unless there is a layer of grease or some other organic substance which it can feed on.
Can mold be killed by heat?
The sensitivity to heat of vegetative cells makes thermal processing a very useful process for ridding acidified foods of these pathogens and other microorganisms which could cause disease or spoilage. Most yeasts and molds are heat-sensitive and destroyed by heat treatments at temperatures of 140-160°F (60-71°C).
What promotes mold growth?
What promotes mold growth? Mold requires water, food, and oxygen to grow. It also requires an environment with a temperature it can survive. Water leaks, flooding, high humidity, and condensation all provide moisture mold can use to grow and spread.
How can I dehumidify my house naturally?
Ways to Naturally Dehumidify Your Home Absorb the Moisture. If you position pots of calcium chloride in problem areas of your home, you should see a quick reduction in humidity levels. Vent Your Home. Remove Indoor Plants. Take Shorter Showers. Vent Dryers. Fix Leaks. Install a Solar Air Heater. Switch to Dry Heat Sources.
What’s the ideal humidity inside a house?
What is healthy humidity? Most people find that a relative humidity between 30 to 60 percent is the most comfortable, with indoor humidity ideally between 30 to 50 percent.
How can I lower the humidity in my house?
How Can I Reduce My Humidity Levels? Use Your Air Conditioner. Actively Use Your Exhaust/Ventilation Fans. Take Cooler Showers. Fix Any Leaking Pipes. Keep Your Gutters Clean. Dry Your Laundry Outside. Get a Dehumidifier. Move Your House Plants.
