So went about two weeks with no moles in the trap - changed the set tactic and got three moles in 4 days. So what tactic did I use? Locate the runs - with the trap set push the jaws down into the soil without prepping or digging. Make sure you support the plate and actually press the plate down into the soil approx 1/2 inch. Worked great!
I know these things work, that's why I bought them, I got to say out of the box the springs are so strong I haven't been able to set them.
My next step is to try using a vise, but trying to be safe because they can do some major harm if they bite you. I can hardly weight to see what they will do to a mole, maybe cut the mole in half. I got it to set when I did it right by hooking the spring, I was trying to set it by the bars lower than the spring.
