The key to preventing scorpions is to eliminate harborage sites around the property including woodpiles, trash and debris. Homeowners should remove stones and landscape timbers from the property, and store firewood at least twenty feet from the home and five inches up off the ground.
Since scorpions can enter structures through torn screens and holes and cracks in building exteriors, it’s equally important to seal cracks and holes on the outside of the home with caulk and repair any damaged window and door screens. Scorpions can also enter homes through poorly fitted garage and entry doors. If light can be seen streaming into a darkened garage from the exterior, the seal beneath the door should be repaired.
