I would not encourage bats to nest on or near any building. Once they move in they will be looking for any and all of the tiniest crevices to work their way into and you will spend years trying to get them to go away. Little brown bats are like flying mice and big brown bats are like flying rat's.

Hello,
I made a real nice bat box years ago and attached it up about 20 feet on the side of a big pine tree. I never got any bats. Then I read somewhere that you never mount them on trees, always on a building. Hope this helps.

MFWD;

I have heard this advice about the tree vs building too. I always wondered where the bats lived in the many thousands of years before humans built our buildings? There must be enough caves and south/southeast facing cracks in nature. Regardless I have placed bat houses in all the recommended locations and the bat house rotted before it housed any occupants. But I built a new garage and within weeks both attic louvers were occupied! I guess the current evolution of bats need buildings. I'm looking forward to successful bat house installation stories.

I've had good luck with bat houses, and bad luck. The best was a rather tall, slender bat house, probably 8x8x30 tall, with probably 20 dowels inside that go about half way across inside the house. That one was mounted about 20' up in a pine tree, at the edge of a patch of trees. No major water supply nearby. Dozens of bats.

The worst was my current bat house, probably 4 Deep, 20 wide and 30 tall. Also with dowels inside. Mounted on the side of our pump house, for 6 years now. Nary a bat.

Obviously my predictions on location and design have a lot to be desired. We do still have bats - dozens of them nightly, but they aren't roosting in my fine looking bat house. I have no idea where they roost, but they are certainly the world's best mosquito control.

Maybe these two PDF Bat Hose Plans will help.

I've got a homemade bat house a fellow from work gave me. His son made it for boy scouts years ago and it weighs about 60 lbs.

From attached bat ebook:

The place you choose to attach your bat house should be free from obstructions with at least 20 feet of open space. This will allow the bats to locate the house and easily fly in and out. In order to provide a secure and undisturbed roosting location, bat houses should be placed at least 15 feet high. At this height, the bat house will also be exposed to more sunlight throughout the day, especially if it is facing southeast to take advantage of the morning sunlight.
