I've had success with chunks of Juicy Fruit gum tossed in area of mounds. Would buy a 5-10 piece pack, tear each stick into 4-5 peices and toss them. They like it, eat it but it clogs their system fatally. Sad, but with other wild animals around, poison not an option.
Few years ago we had a long, very wet 6-9 months. The moles spread like never before and couldn't use the gum due to dogs.
We've finally found success with Gardens Alive Mole Treatments, both granular and liquid. Switched to liquid after big issues with chipmunks and liquid is purported to make land undesirable to all burrowing animals, even large ones like armadillos. So far, working well for moles; jury out on chipmunks. Gardens Alive is a mail order company selling non-toxic lawn and garden and other items that really work and they guarantee them. Many items they have developed and they are sole source. Found their items and grass seed (love the newer Turf III) to be worth the money and shipping and I'm frugal.
