Dang Chris with a rig like that how long does it take you to mow your yard, 10 minutes? Tell you what I would use on your little buddies, 3 minute smoke tubes. I had one last year in our yard, took all I could from him. Finally after driving off into one of his holes with the front wheel of the riding mower and almost breaking the axle, I decided it was either him or me. I pulled out the water hose and filled each hole took him about 15 minutes and he came out of one of the holes. I knocked him in the head with a shovel and that was the end of my problems.
