How does mold grow?

Mold reproduces by reproducing small spores. They are so small. They’re almost invisible. This makes them easy to spread in the air and through water. The spores can be spread by clinging to clothing and fur.

Mold can grow indoors and outdoors in different forms. Some molds can be seen, while others are harder to detect. To grow, all types of mold require specific conditions.

Mold spores can survive in environments where normal mold growth is not possible. Still, they will only begin to grow when they are in an environment with suitable moisture, oxygen and a suitable temperature, as well as organic materials for them to feed on.

Let us break down the conditions in more detail:

Moisture- Moisture is required for all types to spread and grow. Mold thrives in humid and damp conditions, so it’s best to keep walls and carpets dry. wondering how to remove oil paint from carpet then find out here now.
