Application Method

Install one-way exclusion devices over wildlife entry points to allow animals to exit but prevent re-entry. Devices include: one-way bat valves, repeating live traps for squirrels, one-way doors with weighted flaps, and excluder funnels for various species. Before installation, seal all other entry points leaving only primary entry with one-way device. Animal exits through device but cannot return. Leave devices in place until confident all animals have exited (typically 3-7 days, longer for bats during maternity season). After exclusion confirmed complete, remove device and seal final entry point. Requires careful inspection to identify all entry points - if alternate entries remain, animals will simply use those. Humane exclusion preferred over trapping for most wildlife.

Timing

Install after confirming animals present and identifying all entry points. Never exclude bats during maternity season (typically May-August) when flightless young will be trapped inside.

Frequency

One-time installation for exclusion. Monitor for 3-7 days to confirm animals exited. Permanently seal entry point after confirmation.

Preparation Required

Complete thorough exterior inspection to identify all entry points. Confirm animals present through visual observation, sounds, or evidence. Identify animal species to select appropriate exclusion device. Have materials ready to seal all alternate entry points.

Follow-up Required

Monitor device daily to confirm animals exiting. Confirm all animals have left structure through visual inspection and listening for sounds. Remove device and permanently seal final entry point. Inspect attic or void for damage, contamination, or additional entry points.

Safety Precautions

  • Never exclude bats during maternity season
  • Ensure all other entry points sealed before installing one-way device
  • Check for baby animals before excluding - may need to wait until young are mobile
  • Wear gloves and protective gear when working around wildlife entry points
  • Be aware of rabies risk with bats, raccoons, and skunks
  • Follow state wildlife regulations
