 I like the plastic ones that just come down rather than the old spring ones. They work the same way, but they're easier to set, and they're just as sensitive. You put your cheese, bacon, peanut butter, any combination right in there. Yeah. The other thing I picked up for the mice is outside. It's a topper for a five-gallon bucket, and it's got a hinge on it, and the mice goes to get the peanut butter off the hinge, and it drops them into the bucket.
