How to get rid of yard moles

Does anyone have a sure fire remedy to get rid of yard moles. They are all over my back yard and I am afraid the may move to the front. I am desperate.

Take a light bulb and break it and grind the glass into small pieces. Pour some of the gound glass into the mole hole. I used a 1.5" pvc.

The moles cut their feet on the glass, the cuts infect, they can't dig, and they die.
