You can buy mole traps, but be sure the store (farm stores best) show you how to use them. The poison worms work, but they can be thrown to the surface by the mole and then are dangerous for non-targets. There is also an explosive device which kills them by concussion. Most "folk" remedies are not really very effective including the mole repellents widely sold. The information in the following link is somewhat dated, but should be helpful if you ignore the pesticide recommendations. I personally prefer the second link as usually it is the voles causingg the damage other than the unsightly mounds.
