We use Tomcat Worm Shaped Mole Killer - they work pretty well, and are easy to use. We also have a bada** cat that kills moles in his spare time...

Have you tried mole traps?

Menards and others sell a device that looks like a large plastic thumb tack that sticks in the ground. It has a solar panel on top and causes the tack to vibrate every 15 seconds. The mole doesn't die, just goes away.
