I wish I could get a reasonable count of just one slot of one of my bat houses. Then I could make a good estimate as to the size of my "neighbors." My bat houses are a bit larger than the standard plans available all over the "net" because I wanted more bats in the neighborhood. There is a huge drainage "pond" at the end of the street so the mosquito population was huge when I moved here 17 years ago. Now it is much better.
Actually the first bats in the US with White-nose Syndrome were in a cave in New York:

While many of you were watching the swarm of bats, and thinking of the millions of insects they would eat, I was trying to imagine how much bat guano must get deposited on the floor each season. A true permaculture solution...convert too many insects into an extremely valuable natural fertilizer!
not only that, but most of these bats are eating insects outside of your property, so you get the benefits of large amounts of organic biomass coming from somewhere else. essentially bringing fertilizer to your land.
birds do the same thing but i bet bats can do it a million times better.

The original premise is that by attracting bats, you are eliminating insects that are otherwise harmful to your garden and crops. The primary insects that bring badness to my garden are: A) sow bugs/wood louse, B) slugs, and C) those little white butterflies that lay eggs on my cabbages which turn into worms that eat them. A bat wouldn't do anything to any of the three. The sow bugs are out there in the soil, and crawl up the plant to eat their lunch. Same with the slugs. The little white butterflies don't fly at night.
We don't have mosquitos here, so even that pest isn't a pest for us. In fact, there don't seem to be too many nocturnal insects here. You'll get some moths and june bugs in the summer, but that's about it.
So while I'd love to have the free bat poop to use in the garden, their insect eating wouldn't be that big of an asset for me where I live.
