What We Do About the Big Brown Bat
We favor exclusion, one-way exits and deterrents so the animal leaves on its own and cannot return. Trapping is used only where it is allowed and needed.
Prevention
Keep Them Away
Simple steps that help for this kind of animal.
- Look for bats leaving at dusk
- Never block an opening before the bats are out
- Avoid exclusion in the pup season (about mid-May to July)
- Seal every gap after the bats leave
