I've never had moles but my dad did. I was the little kid with the spade standing near the farthest hill. He ran the hose down the tunnel as far as he could, turned on the water, picked up a shovel, then waited. The critter emerged and we are lucky we didn't hit each other with the back of the spades in our pusuit. We got 'em though!

Thats called quality time. A real bonding experience.
