I have used several different styles of mole trap. These simply work. Do your research on the internet about how to locate the moles main tunnel. Set one of these in the runway and Catch That Mole. These traps come with a cheesy wire that is intended to help "cock" the trap. Just throw it away. I cut a slot in a piece of plywood, lay the trap with the trigger over the slot and step on it to compress the spring. Make sure you set the safety catch until the trap is securely set in the hole where you want it. I haven't sprung it on my finger yet but I have closed it on small twigs just to see what happenned. It is a very strong spring.
