This is what I use, Victor is the brand, it’s called “Tin cat “ I have four around the outside of the house, one inside the pump house, four inside my shop. Some times I don’t even put any bait in them and still catch mice. They check in but they don’t check out. When I catch any I fill a square bucket with some water and give them swimming lessons by placing the trap in the bucket. None of them have ever graduated.
