I know you will think this is crazy - - we did. Buy gummy worms - - not bears or any other - - just gummy worms. Cut them into four pieces and stuff the pieces down the mole runs with a stick. Also, wear gloves so they can't smell you on the gummy worm. We have had cats and dogs that have dug them up but they never stopped coming. We heard this on 'Listen to the Mrs.', a radio show where we live and IT WORKS!!! I couldn't believe it myself but we're seeing it. We roll the yard in the spring and where ever we see a mole run we stuff the gummy worm pieces. They love them but can't digest them. I believe it kills them. Sorry about that but we have had so many that we had to find a way to deal with them. Try it.
