@RocketLanch8- I can tell you that rat glue traps aren't much better. My cat has found a few of them, and getting that adhesive out of a cat's fur is a huge chore. If I know there won't be any children or pets in the area, I will still use rat snap traps. The best rat trap bait I've found is peanut butter, but bacon would be my second choice.
My neighbor recommended some humane rat traps he got at a local farmer's co-op. They're mostly metal live rat traps, but some are disposable. The rat can enter one side of the trap to get the bait, but then a door slides down behind him and he can't back out. My biggest concern is where to dispose of the rats once I trap them. I don't want them to become someone else's problem, but I'm not driving 20 miles into the woods just to dispose of a disease-carrying pest.
