Black mold is a toxic, quickly spreading fungus that exists in homes and buildings nearly worldwide.

Since the substance has been found to cause harmful health effects to humans and pets, it is important for homeowners to identify and remove black mold as soon as possible. 

After black mold remediation, an individual can once again dry the area as completely as possible to prevent new infestations. The garbage bag of mold should be removed from the house and disposed of in a landfill to prevent airborne spores from escaping and repopulating. By frequently checking mold-prone areas and taking steps to prevent damp conditions, most spaces remain free of fungus after an initial cleanup.
