Hey im a golf course super and am no stranger to gettin rid of moles. There is a great product called Talaprid, its a poison in the form of gummy worm bait and very easy to use, simply stick a fat screw driver down into the most active part of the moles run and feed the bait down into it, do this every few feet and rest assured you'll be mole free in a few days. If you go with this solution please read the instructions for yourself and pay close attention to the MSDS info because it is POISON (if you have pets or small courious children you may want to consider option 2) Buy a Mole trap, most hardware stores have these, follow the instructions as to how to laod it and watch your fingers cause mole traps pack a serious punch. The trick is all in how you set it and where you set it in the run. Place the trap in a long straight active section of the moles run, You will have to cut a small section of the run out in order to properly set the trap, save this section of removed turf to cover the trap up after you have gotten it into position, be sure to cover it well so no light can enter the moles tunnel because the light will scare the mole into rerouting his tunnel.
Moles are smarter than you might think stick with it
