I am a trap and peanut butter person myself.
Me too. And those traps are deployed outside the trailer, I'm not inviting them to an inside meal. A bucket trap makes a good tool if there are a lot of mice in the vicinity. A good cat, one that delights in the hunting of mice, is the best deterrent but if they get inside, it will a long hunting process to eliminate them because they will only exit to drink or eat. I have two hunters, here, and they will spend days looking at the last known departure point of an observed mouse. They are the best predators.
