Bullfrogs. That's the answer.

Go down to the nearest pond and get a bunch of 'em and station one at every window. That'll work.

As John Sebastian sings:

                      "Did ya ever wake up with bullfrogs on your mind
                        Did ya ever wake up with bullfrogs on your mind
                        That's a sure sign you got bullfrong on your mind"

BUUURRRRREEEEP! RIBBITT!! RIBBITT!!!
