Moles

One or more moles are digging up the grass at the house we’re staying in. Every morning we come out to find wonderful little piles of soil, all carefully sifted through, lying on top of the grass, and covering it up. The moles has no obvious system. The holes appear randomly around the grass area, and the piles are both big and little.
My brother-in-law says traps should be set for them, but I can’t imagine the owners of the house acquiescing to such a plan; I think they’re more into ecology than that. The moles are little like earthworms, it seems to me. They shift the dirt about and in the process make it much more friable. As a garden companion, a mole could be quite useful, if only he’d dig in the right place!
