Bats are amazing neighbors. For years our neighboor had a massive pine tree that was hone to a pretty significant bat population. We would always see them come out at night and start feeding. Mosquitoes were never an issue. A few years ago the tree had to be cut down because it was rotting inside and was at danger of falling down. Unfortunately the bats haven't returned, and everyone in my neighborhood is now fighting the mosquito.
The only issue I have with bats is I am now terrified of them. Several years back my kids Taekwondo instructor, a 21 year old picture of perfect health magnificent human being, was killed from rabies after a bat brushed against him in the night while taking a pee on the side of the road. Months later after it was too late signs of rabies appeared and he died in hospital. It was devastating. The bats in my neighbourhood commonly swoop down near you if in the yard and it is now scary.
I am not sure by what part you think is nuts? Worrying about bats? I don’t like to play with odds and now personally know someone who died from it. I would rather not take a chance. Here is an article about his death and the rabies in the bats in our area. https://vancouverisland.ctvnews.ca/mobile/man-21-dies-after-...
I woke up one night with a bat flying circles around the ceiling of my bedroom. It flew all over my house until I trapped it in a room. It flew with total precision, like it was at home in a cave, nothing like a confused bird flapping around in your house.
I paid $400 to have it captured and tested (which involves killing it). It was negative. It could have bit me in my sleep, and I was glad to not get that series of shots (at the time it was those ones that go into your gut) or wait it out and wonder if I would die a year later.
