You may think that raccoons are cute. You may call them trash pandas. But the fact is that raccoons can be and are incredibly destructive. When they decide that your attic is the best place to create a house, they can tear up your insulation, chew on your wiring, and their urine and feces can damage your ceilings. If you believe you have raccoons in your attic, you need to call a pest control professional as quickly as possible.
