Completely squirrel-proofing your home after professional removal prevents repeat break-ins. Here are top proofing tips:
Seal All Openings Larger Than 1/4 Inch
Using durable materials, fill any gaps, holes, or cracks in exterior walls, roofs, and foundations that exceed 1/4 inch width. Squirrels can squeeze through surprisingly small spaces. Metal mesh, concrete, wood, or steel wool are best.
Install Chimney Caps and Repair Fascia Boards
Caps keep squirrels from dropping down chimneys. Inspect all exterior overhangs and patch fascia board gaps with sturdy metal flashing. Use high-quality caulk around windows and vents.
Cover Vents with Steel Mesh or Concrete
Replace flimsy plastic vent covers with 1/4 inch steel mesh secured with bolts. For standard vents, stuff concrete mesh inside openings. This deters gnawing while still permitting airflow.
Trim Back Branches Overhanging the Roof
Prune any trees or shrubs growing alongside or above the home. Eliminate these “squirrel superhighways” giving them roof access. Keep clearing vegetation back several feet.
Remove Clutter Against Exterior Walls
Piles of wood, debris, tools, and other items near exterior walls offer shelter for squirrels to nest under. Also block access under porches and sheds. Creating an 18 inch clearance helps.
Routinely Inspect Known Problem Areas
Check former entry points, vulnerable vent openings, eaves, and attic spaces regularly for new chewing or holes. Early detection of re-entry attempts makes swift exclusion easier before major damage occurs.
A clean perimeter with robust structural barriers goes a long way toward keeping squirrels from infiltrating your home again after removal. Don’t get complacent – stay vigilant.
