We keep a can of that wasp spray by each door of the house. It's my personal defense weapon! I got stung after grabbing wasp nests while weeding 3 times last year. My husband keeps a flashlight by the door to use with the wasp spray since the problem crops up so often. The flashlight is good for defense, too. So far, though, the only predators we've had to fight off have been wasps, and skunks getting into the cat food.
And seriously, the wasp spray is good for disabling would-be robbers.
