For the last couple weeks the moles have been back, completely destroying my front yard. They laugh at the traps, setting them off at will and scampering away. I can almost hear them laughing from inside the house. So a few days ago I pulled out my 4" wide trenching shovel and put a razor sharp edge on it. I leave it on the front porch and every time I see new tunnels I stab through them with the 15" long, 4" wide shovel blade. Yesterday afternoon I was down to one tunnel and this morning there are no new tunnels. I'm keeping my fingers crossed, hopefully I got them all (for now).
