Best Management Practices to Reduce Structural Pests

Wildlife (squirrels, bats, birds, raccoons, and skunks) can enter buildings via the roof, vents, soffits, and windows.

Integrated pest management combines inspections, pest knowledge, control tactics, monitoring, recordkeeping, and communication to reduce pest problems. IPM seeks to minimize environmental, health, and economic risks by using exclusion to keep pests out. Success of an IPM program can be enhanced by including faculty, students, staff, and administration as part of the solution.


  • Inspect rooflines in late winter and early fall for signs of possible access (openings)
  • Inspect utility rooms, attics, and similar areas on top levels of the building


  • Prune tree branches to be no closer than ten feet from a building
  • Seal openings with exclusion products such as hardware cloth, rustproof “steel wool” replacement products, and flexible sealants
  • Keep foundation perimeter free of debris
  • Keep gable, soffit, roof, and other vents in good repair and made with animal-resistant materials and design
