I used to own 5 acres downstate in Michigan, and fought moles for years. As long as your neighbors have moles, and unless you want to put enough poisen on your yard to kill off all the grubs, earthworms, etc....you have to fight them continously. Most of the poisen peanuts, chewing gum, poisen gas, etc..methods are not very effective. The pronged spring traps will work if modified, removing the four outside prongs, and leaving only one prong on each side. This setup might miss a mole once and awhile, but will kill more moles than the original 6 prong trap by far. Another effect method, if you have the time and enjoy the process...is to stomp the trails down flat, grap a few beers, and set down and watch. If you see any new soil movement, attack with pitchfork or hoe. Moles are sensitive to any noise, and will play possum if there is any activity nearby. They are really noisy as they tear thru new sod, and you can hear them very clearly.
