Bats

So one project I have coming up is putting up a bat house. It's been sitting in my garage for a couple of years gathering dust, and meanwhile I'm getting eaten alive by mosquitoes every summer. Anyone here have a bat house? When do bats typically go looking for roosting locations? I've used bat guano as a fertilizer, so maybe I should hang it over the compost pile...
