Incidentally, bats were evaluated during WWII as possible weapons. True stories:
Some bright boy came up with the brilliant idea of attaching tiny little incendiary devices to a bunch of bats that had been refrigerated (to reduce their metabolism and keep them quiet) and then toss them out the back of an airplane flying over various Japanese cities, in the hopes that the bats would fly down, roost under the eaves of Japanese houses in the early morning, and then the little incendiary charges would go off on their timers and the bats would burst into flame, burning down the houses, which were mostly constructed of wood and paper.
Unfortunately, it was discovered that when you toss bats out of the door of a C-47 at over 200 MPH, the slipstream rips their gossamer little wings off. Oops.
During the testing of this wacky idea, a lower speed test was made (the bats survived) and the bats took it into their tiny little minds that the house provided in the target area wasn't up to their standards. So the whole damned flock of bats found a nearby house more to their liking, and roosted there under the eaves.
The timers worked as expected, the bats burst into flame, and the house burned down.
The house was....care to guess???
Yep. It was the base commander's house!
Lesson: Bats can't read house numbers, or if they do, they really don't care.
An allegedly true story.
