I made a rocket bat house to put up in my vegetable garden this spring when the ground thaws. It will slide onto a 4x4 post as tall as I can get (16’?) . A little ugly, but the wood was scraps from work so it’ll do.
Hopefully they will eat some bugs and leave some fertilizer!
Yeah, not a great picture now that I think about it! The bottom is open and they crawl up into it. There are 2 chambers around 3/4" deep. At the bottom is the tallest shell which goes over the 4x4 post, then there are some 3/4" spacers and a shorter shell, then more spacers and the outer shell. Hope that makes sense.
I have a bat house. Its called my barn. I have a huge colony, probably 200 bats that live in the space between the steel roof and the rafters. They do a number on the insect population. I wish they would inhabit the actual bat house, but they prefer the barn, and I would rather have them around than not! So I sweep the floor of the loft and put the guano in the garden!
Nice. I made one as well back in November 2020 per a blue print I found on line, I added a piece of tile to the roof so it doesn’t rot. I’m thinking about drilling a couple holes just under the top for ventilation, just seems to me it has to get pretty hot in the upper portion since there’s no holes.
I didn’t think I had any bats this summer since I didn’t see any bat crap so I shook the pole and 12 bats fell to the ground, so don’t shake the pole! I put them in a shoe box for the day and they all flew off when it got dark.
They like heat, and they spend the day grouped together for it. As long as there is enough space to move around, they will adjust to where they like. I had about 40 living in my house at one point, up in the soffit sometimes behind shutters. We got the roof redone and i think they are now only at the neighbors house. I am not sure they moved into the bathouse i attached to the chimney next to where they had been living before.
Most expert sources also recommend painting them black or dark brown or dark green depending on how far north you are, to increase heat absorption. They truly like it really, really hot in their houses.
Alas, we have no takers on ours, either, a colony size accommodation mounted on a nearly ideal location, at least twenty feet up on the southern face of an unused chimney, with a totally unobstructed flight path. We bought it with great excitement five years ago, but I have since learned that bat houses almost never get a colony farther than a quarter mile from open water.
I keep meaning to find out if the local park would take ours as a donation, so it could be placed close to the pond.
Try painting it camo to look like an actual tree. I called a bat sanctuary just to get some opinions and they did recommend a light brown to medium brown for me here in Florida so I would think that temperature guide is correct.
