What can IDo to get rid of moles in my yard?

I have been able to reduce the gopher population around our house with a "trap" called "Gopher Hawk".
It actually is more of a guillotine that kills instantly and thus rather humanely. A smaller version is available for moles, if you don't mind a fatal solution.

Plant garlic! We planted it every 6 foot apart on the fence line of our 1/3 acres and while the neighbors had issues we didn't.
