Hopefully your repair job works for you OP. I agree about not wanting to kill them, but wanting them further away from your home.
Just had to share our family's bat story. My sister lives four blocks away and called in a panic one night. She had a bat in the house and her husband was out of town. DH (in his typical "manly" fashion) replies he'll be right over.
I handed him one of the kids' butterfly nets from the garage thinking it might help. He managed to snag the bat in one swing of the net, but it's the two sides of the story I found amusing.
DSis called before my hubby even got home praising how he walked right in there and caught the bat in just a matter of minutes with one swing of the net, then took it outside and let it go. Nothing to it.
Then, DH got home and told me his side of the story. "That things was HUGE

and it wasn't hanging off the wall or bumping around near a window or door easy to catch, it was SWOOPING through her kitchen at FULL SPEED

. I mean it looked like a terradactyl in there. It came right at me

and I just swung the net to bat it away. And caught it!!!

Just cracked me up how well he hid his fear from DSis, she really thought he was so tough. Not nervous or scared at all....
Of course I had to share his side of the story with her later. We all get a laugh out of it now.
And OP, give your hubby some cudos from my hubby for having the guts to crawl into an attic with bats!!!!!
