Can mice, insects or rodents chew through GREAT STUFF PRO?
Mice, raccoons and large pests, if determined enough, can chew though many materials, including GREAT STUFF PRO. When a barrier is needed for large pests, it is recommended a wire mesh be installed and GREAT STUFF PRO applied generously on both sides of the mesh. For smaller insects and bugs, GREAT STUFF PRO alone typically serves as an effective barrier.
