I recently built a bat house. It even has a Bat Girl sticker.
Since I hear bats eat mosquitos, I thought it may be a good idea to attract a few. Plus we had a bat living in one of our vents a year or two ago so I thought it’d be easy to attract them. Turns out, I haven’t attracted any bats yet.
I used the boards I had lying around and I figured out measurements as I went. It’s basically four walls and a roof. On the inside I used some wire fence that I thought the bats could grip onto. This was easier than scratching the insides of the bat house as some plans recommend. Overall, I thought it was just as good as the vent they lived in a while back.
I’m not quite sure why the bats aren’t coming, but maybe they’re not looking for homes this time of year, or maybe it should be more in the sun. Either way, I’m happy with it.
