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 absorbs more moisture than cold air. Some mold needs different levels of moisture.
How long does it take for mold to die without moisture?
FACT: Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth. FACT: With water, molds grow. Without water, molds die but the spores do not. If water returns, the spores regenerate growing colonies of mold.
Do mold spores die when they dry out?
What Happens to Mold When it Dries Out? Mold spores become inactive temporarily after they have dried out but can remain a threat as long as they are present in the environment. Without constant moisture, mold will become inactive but they never die unless you get rid of them completely.
Will mold go away if you remove moisture?
Moisture-deprived mold may indeed appear dried-up and lifeless. In a sense, it is: without moisture to keep it active, the mold fungus mass stops growing and becomes inert. However, while the fungal mass is dead, microscopic spores that trigger regrowth and contamination aren’t.
Is inactive mold dangerous?
Inactive mold is dry and powdery, and the surface layer can generally be readily brushed off the surface. Both active and inactive molds can pose potential health hazards. Health effects from mold can be acute from short-term high exposures or chronic from long-term exposure to lower levels.

Can mold spores travel through air?
Molds, like most fungi, break down plant and animal matter in the environment. They can grow almost anywhere there is moisture and organic material such as in soil, on foods and plants, and in people’s homes. To reproduce, molds release spores, which can spread through air, water, or on animals.
How do you get mold spores out of your lungs?

Does Black Mold go airborne?
Though its spores are not readily airborne, black mold can produce other harmful contaminants more easily found in the air (as explained in the next section). More force is required for Stachybotrys spores to become airborne, as compared to other commonly found indoor molds (Aleksic et al., 2017).
