I'll give my nod to peanut butter baited traps too.
That "Rat Zapper" looks entertaining tho, got any videos of it in action
Dang, I'm having flashbacks to growing up in the mountains now. Usually, the dogs, and the cats tough enough to survive the dogs, kept such events to a minimum. Occasionally tho a porcupine would come in and feeling somewhat invincible, would start chewing up the radiator hoses and belts, etc. While the dogs barking didn't deter them, it did alert me to the need to dispense a little lead poisoning.
-Porcupine is tough and stringy, but after awhile in the pressure cooker, it's not too bad
