⏩We often see that some things like shoes, that and many things are spoilt in rainy season. A greenish or brownish layer is covered on them.

⏩This is because of pest attack on them.

⏩If we keep any materials in those places where air is not present, then they will be attacked by various microorganisms and pests.

⏩When they are kept in places where air is not present then, the water present inside them comes out and they are attacked by pests.

⏩Similarly, if we keep wet grains in large sacks then they will be spoiled.

⏩So it is always preferable to dry grains before storage.
