Causes and growing conditions. Mold is found everywhere and can grow on almost any substance when moisture is present. They reproduce by spores, which are carried by air currents. Water vapor commonly condenses on surfaces cooler than the moisture-laden air, enabling mold to flourish.Similarly one may ask, is moisture mold dangerous?
Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing. Molds have the potential to cause health problems. Molds produce allergens (substances that can cause allergic reactions), irritants, and in some cases, potentially toxic substances (mycotoxins).
Furthermore, how much moisture does mold need? Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent -- ideally between 30 percent and 50 percent, if possible.
Keeping this in view, can mold continue to grow without moisture?
FACT: Although molds cannot grow on inorganic substances such as metal or glass they can grow on built up dust and dirt that accumulates on these items provided sufficient moisture is present. Without water, molds die but the spores do not. If water returns, the spores regenerate growing colonies of mold.
Is it normal for mold to grow on walls?
The most common causes of mold growing on walls are high humidity, condensation and water leaks (which are often hidden inside the wall). Condensation forms when water vapor in the air meets cold surfaces and cools to become liquid. Leaking pipes near or inside of walls are a common cause of mold.
What do professionals use to kill mold?
Scrub the surface mold stains from walls and wood trim with a mixture of 1 qt. water and 1/2 cup bleach mold cleaner to kill the mold. Use a soft brush and work until signs of the mold disappear.

Outdoors, molds play a part in nature by breaking down dead organic matter, such as fallen leaves and dead trees. But indoors, mold growth should be avoided. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.What happens if you breathe in mold spores?
