Since I have lived here, there has been a mole or two on the property. I used some more repellant and it seemed to work for a while, but as the summer went on, they came back and became more destructive. I put down more repellant, but it just seemed to piss them off and now that we have had uncommonly heavy rain, there are spots in my yard that are like a swamp. The moles have gone nuts and are destroying everything! Short of getting up and sitting around with a shovel, is there something I can put down to kill them or drive them off???
