Mold is part of nature. It is found indoors and outdoors, no matter where you live (unless you live in a scientific sterile bubble). Mold will enter your home through doors, windows, or HVAC systems. As people and pets travel through this world, mold spores are attaching themselves to them. Clothing, shoes, bags, purses, and pet fur make excellent vehicles for mold spores to enter your home.
But that’s not all, other less noticeable materials can support mold growth. These materials include dust, certain types of paint, wallpaper, wallpaper paste (Oh My! Miracle Grow for mold!), insulation materials, the latex backing on carpets, fabrics, and upholstery.
