What Is Mold and Why Does It Grow?
Mold is a type of organism that belongs to the fungi kingdom—it is neither plant nor animal. Unlike plants, mold does not rely on sunlight for energy. In fact, ultraviolet light from the sun inhibits mold growth, which is why mold thrives in dark, damp environments. Instead of photosynthesis, mold obtains nutrients by digesting the material it grows on.
The primary role of mold in nature is to break down decaying organic matter, such as dead plants, fallen leaves, and even animal remains. Outdoors, mold is commonly found in soil, wood, and decomposing vegetation. While this process is essential for the ecosystem, mold becomes a problem when it grows indoors.
Where Does Mold Grow Indoors?
Mold spores are microscopic and can settle on almost any surface. Inside homes, mold often grows in areas with high moisture and poor ventilation, including:
- Carpets and rugs
- Paper and cardboard
- Clothing and leather
- Drywall and insulation
- Wood surfaces
- Food items
Bathrooms, kitchens, basements, and attics are particularly vulnerable because they tend to trap humidity. Water leaks, flooding, and condensation create ideal conditions for mold growth.
Is All Mold Toxic?
Not all mold is toxic, but certain species can produce mycotoxins, which may cause health issues such as allergies, respiratory problems, and infections. Even non-toxic mold can damage property and affect indoor air quality.
How to Prevent Mold
The best way to prevent mold is to control moisture. Fix leaks promptly, improve ventilation, and keep humidity levels below 50%. Regular inspections and eco-friendly cleaning solutions like Moldzyme® can help keep your home mold-free.
