Hi guys,
I build a 3-chamber bat house in Switzerland some 3 years ago
I made it as "academical" as I could in terms of construction, materials and placement
Though, after 3 years, no bat settled in
Many bats fly above this garden usually, it's a quiet place, though relatively urban, not much disturbing light, no cats or foxes can access the house, no spiders or wasps inside, it's oriented south and receives direct sun from early morning till approx 2 p.m., there were much less leaves at first, but I always kept the landing area clear, no one ever opens the windows below and there's litterally no light coming from there, the latitude of Switzerland is 45° (Europe is warmer than North America for the same latitude)
I'm out of solutions to have this house populated
Any hint?
Thanks in advance!
