Mold is a type of fungus that can be found both indoors and outdoors. It can cause a variety of health problems, so it’s important to get rid of it as soon as you notice it. Does heat kill mold? The answer may surprise you!

In this guide, we will discuss the different ways that heat can be used to get rid of mold. We will also provide tips on how to prevent mold from growing in the first place.

Mold, or mildew, is a fungal growth that can affect plenty of different organic materials. It’s easily recognizable by its fuzzy appearance and strong, musty odor. Mold releases spores into the air to reproduce, which can trigger allergy or asthma symptoms in people — sometimes even in concentrations as low as 25 spores per cubic meter of air.

Does heat kill mold?

The answer is yes and no. It depends on how much heat you use and how long the affected material is exposed to the heat source. Heat alone won’t kill mold — it takes about 160 degrees Fahrenheit to do that — but professionals use heating methods to dry out buildings after floods to prevent mold growth.

While high temperatures can kill mold spores, they cannot always penetrate deep into materials where mold is growing. This means that heat alone may not be enough to get rid of all the mold in your home.

However, heat between temperatures of 140-160 degrees Fahrenheit can kill most mold spores. This is hot enough to penetrate deep into materials where mold is growing.

If you’re dealing with a small amount of mold, you may be able to get rid of it by increasing the temperature in the affected area. This can be done with a hair dryer, space heater, or even by turning up the heat on your thermostat. Just make sure that the area is well-ventilated so that you don’t end up breathing in too much mold spores.

If you’re dealing with a larger problem, you’ll need to use other methods in addition to heat.

When is heat not expected to kill mold?

Mold is a type of fungus that reproduces via spores that become airborne and settle in damp environments. When these spores land on a surface that has moisture, they begin to grow. Mold grows best in temperatures between 60-80F and requires moisture to thrive, so heat won’t deter it but instead may cause it to multiply more rapidly.

In addition, mold can grow within walls and crevices where airflow is limited, which means that even if you turn up the heat, the spores may still have enough moisture for growth. If you’re dealing with a large problem, it’s best to call in a professional who can treat the area with chemicals that will kill the mold.

How can I prevent mold from growing?

Now that you know the answer to “does heat kill mold?”, let’s take a look at how you can prevent it from growing in the first place.

Here are some tips to help you prevent mold growth:

  • Keep your home clean and free of clutter. Mold loves to grow in dark, moist, and cluttered areas.
  • Make sure that your home is well-ventilated. Open windows and use fans when necessary.
  • Fix any leaks or standing water right away.
  • Use a dehumidifier in damp areas of your home, such as the basement or bathroom.


By following these tips, you can keep mold at bay and create a healthier home environment for you and your family.

What do you need?

  • A source of heat
  • Mold



  1. First, identify an area in your home that has mold growth and is easily accessible.
  2. Turn on a hairdryer and hold it close to the moldy surface, moving it around until the mold is gone. Be sure to keep the hairdryer moving so that you don’t scorch the surface.
  3. Once the mold is gone, turn off the hairdryer and allow the area to cool.
  4. Wipe away any residual mold with a damp cloth.
  5. Repeat if necessary.



So, does heat kill mold? In most cases, yes. But it’s important to remember that mold can return if the conditions that allowed it to grow in the first place are not remedied. If you’re dealing with a mold problem, call in a professional to assess the situation and recommend a course of action. And be sure to take steps to prevent mold from returning in the future.
