I've got a critter that ate most of my tomato plants when they were small and tender. It left a larger plant alone. It also ate my small green pepper and cucumber plants. It tunnelled under my wire mesh fence that surrounds the garden and it's also done some tunnneling in a small (about 3 foot square) area of my lawn. Most of the lawn damage are paths that are shallow that go nowhere, but there are a couple that lead off with a 1.25-1.5 inch tunnel. I know of 2 tunnels under the fence and into the garden.
I was thinking it's moles, but there aren't any mounds and I can't find evidence of the digging leading away from the area. What else?? Could it be ground squrrels?? Rabbits??
