Does anyone have a bat house? I was thinking of constructing a large one in my backyard to help with pollination, eat mosquitoes and give manure. Also was thinking of ways to attract birds to the yard so they could supply manure as well. Gourds for purple martins are popular where I live. I think I remember reading about someone who had homing pigeons in their yard and they said the pigeons fed themselves and pooped in their yard but after researching that, it seems one has to feed their homing pigeons but I was hoping they would feed themselves.
You have to have bats in the area to start with ... then placement seems to be very important in getting them to accept your house.
I like the Dourson/MacGregor bat house:
