Hello!
On the south side of my house I have 6 shutters that need to be replaced. I've been reluctant to do this because I believe bats roost behind some of the shutters. I see some black feces caught in cobwebs below the shutters and have seen bat activity in the summer. What's the best way to limit my impact on the bats? Do they roost here year round? (Suburban Philadelphia) Is there a best time of year to do this? I don't want to displace the bats if possible.
