After a rainy season Mold infestation is very common. The hot and humid climate is a perfect recipe for the germination of spores which are abundant in the air. Spores of molds are present everywhere and have been even seen in space stations and satellites. A number of expensive instruments have been destroyed by these measly creatures which are very sturdy and can grow on almost anything.  The spores of these creatures are very resistant to the most unfavorable of conditions and germinate at the first instant of favorable climate.
