A desiccant is a product or material that can be absorbs moisture from the air, thus reducing the humidity in a controlled environment and thereby protecting goods from moisture damage
Mould is a type of fungus. Moulds are visible clusters of Microscopic filaments of fungal growth. They can grow on virtually any substance providing moisture is present.
If humidity in the air is naturally high due to wet season, regional position like by the coast or another large body of water or in a dampened area, then mold growth can be a recurring problem. This is because mould growth needs darkness, a food source, oxygen and water source to grow. So if there is high moisture it can work as the water source and enhances mold and mildew growth.
