Without looking at a mammal guide, I think it is a shrew. Short tails, pointed snout.
Again without a guide if memory serves, largest component of their diet is meat. So they are carnivores eating worms, grubs, beetles, beetle larvae, and things of that nature. There may be a few that consume a little vegetable matter, but not much. I would not imagine that they would be a problem in the garden. The moles have no external ears, very tiny eyes and a pointed head since they live in the leaf litter and burrows made by moles, chipmunks and voles.
