Mold is a common issue in many homes, but most people don’t fully understand its impact. While it poses health risks, what happens when it dries out? Does it simply die, or does it pose a hidden risk?

People fall victim to the misconception that mold without moisture is dead. However, the reality is quite the opposite. Dried mold doesn’t die; instead, it goes into a dormant mode.

Even in this state, it can still harm your health and property just as much as active mold. That’s why it’s crucial to learn more about mold to avoid potential financial and health problems in the future.

Definitely, in this case, mold inspection won’t be necessary since the mold is visibly present. However, dry mold often affects your indoor air quality, making mold testing essential.

Here, I will uncover the secrets of what happens when mold dries out, the risks it poses, and how you can protect yourself from those risks.

What Causes Mold to Grow?

We all know that mold thrives in areas with high humidity and moisture. Whether it’s your home or workplace, mold won’t just go away unless a mold professional removes it from its moisture source.

But is moisture the only thing mold needs to grow?

High temperatures in specific areas of your home, like the bathroom, kitchen, or attic, can also trigger mold growth.

Mold can also take hold of organic materials such as drywall, wood, and carpet. And if there’s been flooding or water damage nearby, mold can quickly spread and cause further damage.

That’s why it’s crucial to maintain a proper ventilation system in your home and regularly check areas prone to mold.

Also, consider getting a dehumidifier to keep your home’s moisture levels under control. Don’t ignore water leaks—those can create the perfect breeding ground for mold.

What Happens to Mold When It Dries Out?

Just like the myth that swallowed gum stays in your stomach for seven years, many people also believe that dried mold is dead and can’t regrow. But this is a dangerous misconception.

In fact, the latter can be more harmful, as it can directly impact your loved ones’ health.

If you’ve ever believed that mold, once dried, is dead and can’t grow back, I hope this information changes your mind today.

First of all, what we need to understand is that mold is a type of fungus. Fungi can remain in a dormant state for weeks, months, or even years.

To put it in simpler terms, dormant mode is like a deep sleep.

Just like some wild animals hibernate in their dens during the winter, mold goes into a deep sleep when it doesn’t have ideal conditions.

However, once it gets the required moisture, temperature, and organic material, it wakes up and resumes its growth.

Some people tend to take dried mold lightly, thinking it’s no more dangerous than active mold.

This misguided thinking often leads to DIY removal attempts. But here’s the truth: trying to remove dried mold by yourself can be far more dangerous than dealing with active mold.

Is Dry Mold Dangerous?

Of course, dry mold is harmful. In fact, it can be even more dangerous than active mold. How?

Let’s say there’s mold in your room that has now dried out. You might think that simply opening the window to allow natural airflow or using a mop and bleach to clean it will solve the problem.

However, this would be a big mistake. Why?

As I’ve already mentioned, mold is a fungus that enters a dormant state. In this state, it produces spores and spreads them through the air.

Dry mold does the same, and its spores become airborne when disturbed. These spores are much easier to inhale compared to damp, active mold.

What happens then is that instead of removing the mold, you are spreading it throughout your entire home. The result will likely be respiratory problems, allergic reactions, and skin irritation.

To avoid all of these issues, it’s best to hire a professional mold remediation company. They will take the proper precautions to safely remove the dry mold from your home and prevent it from spreading to other areas.

How to Deal with Dry Mold?

First and foremost, make sure that no matter what, you should never touch dry mold yourself. If you don’t want it to spread throughout the entire house, stay away from DIY mold cleaning methods.

Next, immediately call a professional. Most importantly, contact a local mold remediation contractor. Why local?

Because locally based mold removal companies are well aware of your area’s environment and your home’s structure, which makes the entire process go smoothly.

Now, before the mold removal professionals begin their work, there is one important thing you need to do: You must control the moisture and humidity levels in your home.

This will help prevent the mold from becoming active again.

Ideally, it’s better to stay out of the house during the entire process. However, if you prefer staying at home, there are a few precautions you should keep in mind:

  1. Ask the mold professionals beforehand if they will be using a negative air pressure system to contain the contaminated air in that specific area. This will prevent the mold spores from spreading to other parts of the house, allowing you to stay in another room without the risk of mold exposure.
  2. If, for any reason, you need to enter the mold-contaminated area during the mold cleaning process, make sure to wear protective gear such as gloves, a mask, and eye protection.
  3. Ensure that the doors and windows are properly closed so that airborne mold spores do not spread into unaffected areas.
  4. Do not touch any mold-contaminated materials under any circumstances.

If your professional advises you to stay out of the house, there are two main reasons for this:

  • The risk of airborne mold spores
  • Toxic mold issues

Typically, you’ll need to stay out of the house for 24 to 48 hours. However, if the mold situation is severe, you may need to stay out for 2 to 3 days. This depends on the condition of the mold in your home.

Frequently Asked Questions (FAQs)

How long does it take for mold to die without moisture?

There is no evidence to suggest that mold dies without moisture. Instead, it goes into a temporary sleep phase (dormant mode), which may appear as dead mold. However, even in this state, mold can spread through spores.

What does inactive mold look like?

Unlike active mold, inactive mold does not have a slimy or fuzzy texture. It usually appears powdery, dry, or flaky. Due to different types of mold, it may be white, grey, brown, or black in color.

How long do mold spores live on clothes?

Mold spores remain on clothes until they are properly washed. For this, you should set the water temperature to 60°C or higher, as high temperatures can kill mold spores. Additionally, you can use regular detergent along with natural disinfectants like vinegar or baking soda.
