Got bugs in your backyard? Forget the insect spray. Get a bat. Not a wood one, but one of those creepy winged creatures that only come out at night. Bats in your backyard are bug eating machines. One of these little buggers can eat it's body weight in bugs every night. Try the math on that one. Lose a few bats and you get a lot more buggin you than just bugs. Mosquitoes carry West Nile and other diseases. Bats eat them by the thousands, but we're losing them here in Indiana to a thing called white nose disease, so beat the bugs that are bugging you. Build a bat a house.
