The crawlspace of a home is a favorite place for contractors to leave debris behind. Most plumbers, heating and cooling technicians, electricians and every other person who works in crawlspaces seem to not have a problem leaving debris in crawlspaces. Out of sight, out of mind. The problem is rodents and insects enjoy the debris. They can utilize the debris for homes. Wood debris is very attractive to insects such as termites for a source of food. Mold also thrives on many of the materials left behind. Debris could also cause harm to any person who may have to enter the crawlspace to perform a service.
