Well, if your mishap has taught me anything, it's that Arizona mice are marginally smarter than Pennsylvania mice. I once had mice make a nest inside my tractor once... a rather fatal mistake for said mice. No damage to my tractor's wiring, thankfully, but between the bifurcated, singed mice on the floor and the mass of fluff behind the engine, it was an absolute mess to clean up.

Always make sure that your traps are baited and set! BTW, if you're curious about dead mouse disposal, I suggest feeding them to chickens. You might not believe it, but a chicken can eat a mouse whole.
