There are some preventative measures which can help prevent squirrels from entering structures:
- Trim tree branches and limbs to about 6-8 feet away from the structure to prevent squirrels from jumping on the roof.
- Inspect all roof overhangs, soffits, fascia boards etc. make sure they do not have any cracks or holes, and that they are tightly attached to the framing.
- All roof vents should be inspected to make sure they are properly screened, not loose and in good repair.
- Keep bird feeders away from the building, perhaps using a “squirrel proof” type of feeder.
