Hercmech:
When I was a kid we had a bat in the house and my Dad, having had a couple of refreshing adult beverages, figured that bats are rats with wings and decided to shoot at it with Rat shot in a .22. Very interesting night watching that I assure you.
My father was warehouse supervisor at a potash mine up here. They received shipments all hours of the day, and the lights at the loading dock attracted bugs & bats... They kept a tennis racket at the door to deal with the problem!
