My main question is I have 2 potential locations. One is on the SSW gable end of the 1 story attached garage. The outside heat pump unit sits approx. 2 feet away from the wall immediately below. It would mean noise, and updraft fan action when A/C or heat is on. The 2 feet space is a "dead zone" where I really can't plant anything (though weeds inevitably make headway there) so in terms of guano depository, it's ideal, whether I put a receptacle there or not.
The other location is on the same SSW gable end of the 2 story house, but the foundation here is thickly planted with daylilies at the moment. I can mount the bat house a little bit higher here, however.
Thanks in advance for your advice to this newbie!
