These would be my go to gopher trap. I don't think you can miss if done correctly. We used both leg hold and death clutch traps, but my catch rates were much higher with leg hold traps. The disadvantage of the leg hold traps is that it takes a lot more excavating. I mainly used the death clutch traps in fresh holes that were still open. So, no digging. Just set the trap and stake in the opening of the tunnel.
Find a tunnel near a fresh mound with a poker. Excavate a hole in the tunnel. You want to make sure the top of the trap is flush or below the bottom of the tunnel. I don't think you could dig it too deep. If they fall into the trap it's just fine. After placing the trap, cover the top of the hole. I used old license plates. Make sure no light shines through. Gets them almost every time.
I don't get to trap very many now days, but I did get a couple this spring in my Mom's yard. Encroachment into the yard is not allowed and violators are terminated with extreme prejudice. I actually caught one with a leg hold and one with the death clutch. No more encroachment into the yard all summer.
