Cut it in half with a shovel. That's what my dad and I did with 3 moles about two weeks ago. The damn neighbors who don't cut their back yard have a mole infestation, and they like to venture out into our yard.
We have 3 mole traps all setup on the property line where our manicured lawn hits their "field" of a yard. The traps don't work all that well... we've decided the best thing to do is to step on about 3 feet of tunnel....not packing it down, just lightly crushing it. That way, when they start to repair it, we'll see them start pushing the ground back up. Take your shovel and get them out of the ground and cut them in half.
