My granddad had some mole traps....wish I had gotten them after he died. You mashed the dirt down on their run and set this trap over the flat place you made, when the mole came along and pushed the dirt back up it tripped the pan and the trap, which was spring loaded and had some spikes that pointed down, and they slammed down into the ground and the mole, thus spearing it and killing it....it was cool as all get out.
