I found the best way to use traps, is to build a wooden box for them with a lid and a rat sized entrance. It stops anything larger, like inquisitive pets, from getting injured, the trap can't jump about when screwed to the base and the rat can only approach the bait from the optimum direction guaranteeing a clean quick kill.
