Caught 2 moles so far. Dont go by the directions as everyone else has said. Just find a tunnel and set your trap with the safety on. Use the claws to judge how far apart to cut into the dirt. Use a hand trowel or small shovel to cut into the dirt to make groove in the dirt for the claws to move through. Press the tunnel down in the middle of your 2 cuts and put the trap in place until its so far in that any movement will set it off. Get it to where it sits on top of the smashed in tunnel without going off and then release the safety. What does the trick for me was watering the lawn around the area. The worms will go for the water and the moles will start to move. I set 4 traps for better luck.
