@Hemophobic, Hi Angie
, I'm here to ask a question but I read your post, if mosquitoes become a problem this year, you could try mosquito dunks in the catch basin, it's not a poison but it's naturally toxic to mosquito larvae, it was recommended to me by people who use them on farmland, so I figured they'd take care of my birdbaths OK!
Anyway, any help anyone can give me, please, I inherited this bat box when I bought the house, from what I've read about bat boxes, this is like an illustration on How Not To Put Up A Bat Box, I haven't any idea if it's ever been used, and I'm not in a position to sit outside at night with a flashlight and see what happens. I haven't seen any bats since I've been here, at sundown and such, but that doesn't mean they aren't here. I want to have my handyman take it down, but I don't want him to disturb any bats that could possibly be in there, or anything else that might have taken up residence, is that likely, any way I could tell?
