Molds are tiny fungi that grow in warm, damp environments. They can appear as fuzzy patches in various colors, such as green, black, or white. Molds play an important role in nature by breaking down dead organic matter, like fallen leaves and decaying food. However, they can also cause problems in homes by damaging walls and furniture, and some molds can produce harmful toxins. Molds reproduce by releasing tiny spores into the air, which can easily spread and settle on surfaces. Common places to find molds include bathrooms, kitchens, and basements. To prevent mold growth, it's essential to control moisture levels and ensure proper ventilation in areas like bathrooms and kitchens.
