Hi, I'm new to the community and this will be my first (of many!) question. My wife and I will be spending 6 months a year in the beautiful Tuscan appenines starting next year. We are in the process of renovating / extending a farm building and, when I build the garage I would like to build it in a way to attract bats and perhaps dormice (ghiri). The garage would have to be secure so no large openings but I could introduce holes in the apex of the roof. Any ideas?
