For the first time, my back yard is littered with small piles of dirt. Nice rows of them, by the dirt being pushed up by moles. A couple years back, I think one ate a good bit of the strawberry patch over winter, but the thing disappeared come spring. Maybe the cat had something to do with it. But now it seems, that a whole group has suddenly found a liking to the yard. Any words of wisdom or tricks to deal with them? Thank you.
