Mold Truth: Does Mold Die When It’s Dry?

Mold Truth: Does Mold Die When It’s Dry?

With how difficult it is to totally remove mold, it begs to question, does mold die when it’s dry? Contrary to the common belief, when mold dries, it is not dead. Mold is a fungus, a living organism that grows, breeds, and requires nourishment to survive. Mold thrives and multiplies when the environment supplies moisture, nourishment, and warmth, as is commonly found in homes here in Fort Myers, and throughout Southwest Florida. When the moisture is taken away, the mold can temporarily become dry and stop growing. However, once moisture returns, the mold can reactivate again.

What Causes Mold to Grow?

Mold will grow where the conditions are favorable-warm, moist, and nutrient-filled locations. Fort Myers homes often provide the perfect environment for mold to thrive. High humidity and warmth give plenty of moisture to fuel the mold. At the same time, household materials such as wood, paper, drywall, and other organic materials provide nutrients for the mold the spread. Basements are a hot spot for mold growth in northern states, while the most popular places to find mold growing here in Fort Myers, Florida, are bathrooms, kitchens, laundry rooms, and poolside patios.

Mold Spores Lacking Moisture: Will They Die Or Sleep?

As mentioned previously, when mold lacks moisture, the fungi will hibernate, it will not die and dry out. Once moisture is available, the mold spores become reactivated as if a restart button was activated, and the growth begins again as if it never stopped. Depending on the species, mold can stay dormant for years in the right circumstances. Certain species of mold have been recorded as remaining dormant for hundreds of years due to being present in the perfect environment.

While keeping your indoor humidity level between 30%-60% helps manage the prevention of mold growth, active mold growth in your home will require remediation to eliminate the problem and ensure it will not begin to grow again. Mold can develop on wet or moist organic materials in your home within 24 to 48 hours of the moisture exposure. To eliminate the mold, and ensure it will not reactivate again, you must eradicate the mold and all contaminated materials as well as solve the moisture problem. iMold technicians can solve both of these problems for you.


Dry Mold: Will It Still Cause Problem?

When mold dries out, the spores become temporarily inactive. However, dry mold spores are still able to cause undesirable health conditions. When mold is present, even dry and inactive, allergic reactions such as itchy red eyes, runny nose, coughing, and skin rashes can occur. Depending on the species of mold and the individual’s immune response, the reactions to mold may vary from mild to severe.

Dry mold spores become light without moisture weighing them down; this weightlessness allows them to become airborne easily. Airborne spores are one of the easiest ways for mold to spread and contaminate people, pets, and surfaces in your home. If your home has dry mold, not allowing a professional to eradicate the mold from your home can cause the spores to spread through the home and reactivate in new areas through your home when the conditions are preferable. In Southwest Florida’s humid climate, conditions can become preferable for mold reactivation at any given time.

What Humidity Level Will Allow Mold To Die?

While the mold will not completely die, but it will dry out, humidity levels between 30%-60% are preferable in the prevention of mold growth. Warm air also absorbs more moisture than cold air, so allowing your windows to stay open for an extended length of time may invite increased humidity as well as humid air into your home, inviting mold to grow as well.

Moisture is required for mold to grow; the oxygen and warmth provided in warm, humid climates is perfect for mold. Some molds, however, require different levels of moisture and can survive with little water present. Interestingly, certain species of molds are also known to survive in deserts. The best way to combat and prevent mold growth and dry mold from affecting your home is through complete elimination by our iMold professional mold remediation team, and then consistently controlling the humidity level in your home.
