I installed mine in the top of an old barn. All of the literature I read said to give them a SW exposure so they could stay warm. I don't think they have to worry about that around here. I do occasionally check and clean out wasp nests in it. Oh well, maybe someday.
Jeff, LMAO about the baby bat climbing your leg.
Sure, its funny NOW! Thank God no one was home to hear me scream and flail like a 12 year old girl.
