Heating the environment above 30 degrees Centigrade (86 degrees Fahrenheit)
would inhibit mold growth.

What affects the growth of mold?
The most important factors influencing mould growth are
moisture, temperature, type of substrate and exposure time
, whereas less important factors are, e.g. availability of mould spores, pH, light, oxygen and surface roughness (Vereecken and Roels, 2012).
What causes mold to increase or decrease?
Mold will grow in places with
a lot of moisture
, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. Mold can also grow in dust, paints, wallpaper, insulation, drywall, carpet, fabric, and upholstery.
What humidity grows mold?
High Humidity
Humidity levels typically need to be at
55% or higher
before mold begins to grow. Humidity mold can be controlled in your home through proper ventilation, which can reduce the likelihood of mold presence, and using a dehumidifier.
What is the best temperature 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.
How do you know if mold is growing?
Most mold is unmistakable, but sometimes small or largely hidden growths just make a surface look dirty. A quick test for mold can be done when you
dip a swab in diluted bleach (1 part bleach, 16 parts water) and dab it on the wall
. If the spot quickly lightens (or keeps coming back after cleaning), assume it’s mold.
What kills mold?
A bleach solution
also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don’t rinse. Mix a 50/50 solution of ammonia and water. Spray on the surface, wait two to three hours, then rinse.
How long does it take for mold to grow?
Mold growths, or colonies, can start to grow on a damp surface within
24 to 48 hours
. They reproduce by spores – tiny, lightweight “seeds”- that travel through the air. Molds digest organic material, eventually destroying the material they grow on, and then spread to destroy adjacent organic material.
What are the symptoms of mold in your lungs?
- coughing.
- wheezing.
- shortness of breath.
- fever (rare)
- worsening of asthma symptoms.
What diseases are caused by mold?

interstitial lung disease
and hypersensitivity pneumonitis, sarcoidosis, and recurring cold-like symptoms, sinus infections, and hoarseness.
How do houses get mold?
Why is mold growing in my home? … Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing
indoors when mold spores land on surfaces that are wet
. There are many types of mold, and none of them will grow without water or moisture.
What temperature does mold start to grow?
Temperature: Most molds cannot grow below 40° F. This is why food is typically refrigerated at 39° F. Mold grows best
between 77° F and 86° F
, especially if the air is humid. Water: Molds thrive in damp, humid, and wet conditions.
What is a good humidity level to prevent 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.
How can I dehumidify my house naturally?
- Absorb the Moisture. …
- Vent Your Home. …
