If your insulation is wet, it is not something that you should simply ignore. This problem will not go away on its own and will worsen the longer it is left untreated. Because mold is attracted to dark, damp spaces, your home’s crawl space is the prime spot to facilitate its growth. Once mold starts to form in your crawl space, it has the potential to spread to other parts of your home, like your living room or bedroom. This aggravates asthma symptoms and allergies.
