I'm new here, and this is my first post, but it's something I do know about.
I have been using rat traps since the late 70's and they work great. One thing you want to do though is drill a small hole where the animal will be trapped and screw up from the bottom a very very pointy wood screw.
When the trap is tripped by anything larger than a squirrel, you will want to impale the animal onto that screw so it doesn't get away. You don't need much, but a 1/4'' or so sticking up will do the trick.
Also, when you set them, scrape the ground down to dirt in a five foot circle. It makes it very easy to find the trap and also makes the animal wonder what the hell is going on down there. Set the trap, baited with peanut butter and place it in the middle of the bare ground and you will catch a squirrel.
I have set five traps and filled them each twice in a day if there are squirrels around. It is a good idea to have the trap tied off in the event you catch anything larger than a squirrel.
I have also used this same trap set under water to trap fish. I screw the trap to a stick and set it on its side and bait it with crappie nibblets. Those babies are deadly. A fish will swim up and take the nibblet and the wire bale will slam the fish against the wood screw and hold it tight.
I like rat traps as they can be used a couple different ways. I have never had any luck snaring fish, but I have trapped them.
