Without a constant supply of water, mold will “go to sleep”. However, the spores never actually “die” considering that they can come back to life once more moisture becomes available. If you want to prevent the mold from growing in the first place, ensure that you dry any wet materials within 24 hours.
Correspondingly, will mold go away if dry?
Mold spores never truly "die" because they can always begin to multiply again at a later time if new moisture becomes available. For this reason, you should always go one step beyond removing the moisture. After drying the mold, you should also remove the spores themselves from your home, using a vacuum cleaner.
Subsequently, one may also ask, will black mold die if moisture stops?
Won't the black mold simply die without the moisture it needs to thrive? With these four staples, mold can survive almost anywhere. It is true that dried-out mold stops growing actively. Spores need moisture to multiply, so removing excess moisture can help you stop the spread of mold.
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.
