I thought my terribly disruptive tunneling critters were voles. I have seen voles in the garden before. So I set a mouse trap in the "vole" tunnel hoping to get rid of the ones that were tearing up my garden. So far I have caught 2 shrews. I really don't want to eliminate the shrews but whatever is tearing up this garden has to go. Anything I plant in the ground here gets pushed out of the soil or tunneled around causing the roots to dry out. Those tunnelers have already cost me a few hundred dollars in terms of plant and crop production. They killed my foxglove and all my asparagus plants near the garden. They may even be responsible for the loss of my rhubarb. I can't risk losing the currants and other plants in the area.
Poor little shrews. There was plenty of room for them in other areas.
