Bat Returns? #349956

Asked August 04, 2016, 11:59 AM EDT

All of a sudden this year, in the past week, we had three occurrences of a single bat in the house. I think it (they) found the air intake for the fireplace. It's strange in that it's been there for years without any bat problems. Anyway, the first time I caught the bat and released it outside. Two days later the same or another bat was back. This time after catching it, I drove it eight miles away before releasing it. A couple days later another bat visited our living room. Can a bat find it's way back from eight miles away?

Expert Response

We couldn't find reliable information about the release distance needed to keep a bat from returning to its territory. However, Swiss wildlife experts determined that bats released there at about 25 miles distance did not express homing tendencies.

Some bat species are migratory so it's likely they are able to return to a capture location from a considerable distance.
