Mold is found in nearly every environment including a certain amount found in every home and workplace. This is considered “normal fungal ecology”. It enters your home from the outside in many ways. It can be brought into your home by attaching itself to your clothes and shoes. Your pets can bring it in after spending time outside. It can also enter through your windows, vents, and heating & air conditioning systems. It is virtually impossible to prevent mold from entering our homes. Most of the time, it will land on surfaces throughout your home and stay dormant to be cleaned during normal home cleaning practices. Problems occur when mold lands on a surface that provides it with moisture thereby allowing growth. Therefore, the real problem when you have mold growing is the moisture source from which it is feeding.
