It seems strange that something so common as mold could be as dangerous as it is. Mold, however, produces something called mycotoxin, which is what scientists believe makes people and pets sick.
Mold has been proven to aggravate allergies and asthma, and is considered a significant health risk for the very young and very old, as well as pregnant women.
To make matters worse, mold spores are kind of like pollen, in that they can float around your house even after you’ve killed the main source. This can cause ongoing health problems and also lead to mold continuing to grow and flourish, even after you’ve killed it.
Mold growth starts in as little as 48–72 hours after water damage occurs. If left untreated it can spread at an alarming rate, especially in warm and wet months of the year.
