How can I get rid of moles and voles once and for all?

Ronald Bowman
by Ronald Bowman
I have tried traps, poison worms, solar noise makers, chemical repellents,
you name it. Our yard is on a hillside so drowning the pesky little critters would not work. Haven't tried gas yet. Heck, I even placed broken glass in the main furrows. Some of these ideas worked for a while, but they are back. I live in the Seattle area and would relish an idea that is tried and true and does not include explosives. I am losing the war miserably. Please help.
