Wishful thinking. I get mole hills in my lawn, garden beds, fields, woodlots, and even in the gravel driveway. They have no boundaries near as I can tell. Plus I like lawns. So, no plans to eliminate mine. Ah - one spot I've never seen one is inside the chicken yard - although likely if they did pop one up, the hens would make short work of scratching it down to nubbins.
