Does Mold Naturally Dry Out and Die Over Time?

Does mold eventually dry out and die? In this blog, we'll answer that question, as well as how to prevent mold from returning.

Mold spores are present everywhere and often thrive in optimum conditions. They may go unnoticed to the naked eye in the early phases, but when exposed to moisture, they can multiply rapidly, revealing them in big numbers. Mold can cause respiratory problems and sinus infections if it is not dealt with promptly. A widely-held belief is that mold will eventually dry out and die. Mold thrives on a variety of conditions, including moisture, food sources, and oxygen. In this blog, we will discuss whether mold can dry out and die, as well as how to avoid it returning.

4 Facts About Mold When it Dries Out

The first step in mold removal is to identify and remediate any moisture sources. Drying out mold is the initial step, but there are other aspects you need to be aware of:

  • Just because mold is dry, doesn't mean it is dead

    Mold can "dry out" if it is deprived of its moisture sources. However, this does not imply it is dead. Instead, mold becomes inactive temporarily and will react if exposed to new moisture.

  • Dry mold spores can travel through the air

    Dried-out mold is more likely to become airborne. Because dry mold is lighter and more easily able to float into the air, it spreads faster than wet mold. If a favorable habitat for growth is provided, damp mold may develop again.

  • Even when the mold is dry, it may still be harmful to your health

    Although dry mold may not seem dangerous, it can actually be harmful to those with respiratory issues, allergies, or other sensitivities. Dry mold is more likely to become airborne and affect overall air quality.

  • Even without moisture, mold can survive for extended periods

    Mold can remain alive for an extended period, even while dormant and in a dry state. Mold that has dried out may live for years in particular circumstances. If it regains moisture, it can come back to life and keep growing.

Only addressing moisture sources is not sufficient to treat mold. It is also critical to have complete and precise mold remediation for long-term mold prevention.

Mold Infestation: What Causes Moisture Problems That Lead to Mold Growth?

Without the proper amount of moisture, mold will have a difficult time growing. Both water intrusion and high humidity levels can cause mold. Poor foundation drainage can cause surface or groundwater to enter your home. Water from storms can enter your home through tiny holes or cracks in the roof, windows, or walls. Floodwater doesn't only wreak havoc above ground - it can also seep through cement floors in buildings with slab construction, causing mold to grow on furniture, drywall, or walls.

Mold thrives in locations without free circulation of air, such as damp materials or rooms with limited ventilation. If the indoor relative humidity stays below 60 percent and above 30 percent, and no cold-condensing surfaces are present, mold will not be able to grow. However, eliminating any sources of dampness might prevent mold from growing and spreading, but it is not easy to destroy completely.

What Happens to Mold When It Dries?

Mold spores can survive for a long time once they have dried out, although they become ineffectual after a period of time (usually several days to months). Mold can cause a range of uncomfortable allergenic symptoms such as runny nose, rashes, itchy eyes, sneezing, and coughing. Because mold spores are light and easily carried along with the air, they may become airborne even if they are dormant. Mold spores can travel more than a mile in a single minute when flying, so it's important to eliminate air-conditioning vents and any other sources of dampness. When mold spores are airborne, they may move from one location to another and settle in an environment with all the necessary components for growth. Mold requires moisture to grow, but it may exist dormant for a long time until it comes in contact with water or high humidity.

As we stated earlier, mold needs moisture to remain active -- but becomes dormant if there isn't any. Mold spores won't die unless you get rid of them. Mold thrives in damp, dark places, and when it returns to life when moisture is once again present, it multiplies rapidly, posing significant health risks. Certain species of mold spores can remain dormant for multiple years under the correct conditions. When you have an active mold problem in your house, simply drying it isn't enough; it will find a means to live, and spread, once more. The only way to stop mold from coming back is to get rid of anything it has touched and have professional mold remediation done.

How to Keep Mold Away for Good

Mold, in particular when it's severe, can be dangerous and unpleasant to live with. Mold can wreak havoc on the structural integrity of your home. If you detect mold in your property, it's critical to contact a professional since they have the appropriate equipment and expertise to get rid of mold.

Not only is it important to remediate mold, but you must also take care to control the moisture and humidity in your home as these create an environment where mold can grow quickly. Reduce the potential for mold growth by cleaning up water as soon as you see it. By insulating surfaces that are magnets for condensation, you can prevent the problem before it starts.

A lower level of humidity in a room helps prevent mold from developing. Use your dehumidifier to keep the humidity level between 40% and 60%.

Frequent maintenance and repairs are important for both the interior and exterior of your home. Regularly check your ceiling, crawlspace, basement, plumbing pipes, and windows for leaks.

To keep mold from growing, you need to regularly repair leaks and clean your gutters.

If there's no moisture, mold will remain inactive but not die. This indicates that when it is exposed to any sources of dampness, it can come back and multiply. It's also crucial to provide adequate air circulation to remove extra dampness and stale air, which can promote mold growth.
