Does anyone have a link to good plans for a large bat house? Apparently my large colony of bats has succumbed to the white nose virus. Very sad. We used to have hundreds in a big nursery colony, living in the attic. This year, only a few individuals. I think this is why we have a mosquito problem this year. Anyway, I never really liked them in the attic, but the benefit outweighed the guano I had to clean up. I would like to put up a bat house in the hopes that new bats will come and choose that instead of the attic.
