Lawn Damage (From Above, Not Below)

Lawn damage can happen from squirrels, digging to cache nuts and acorns, then digging again to retrieve, and going after grubs, insects, bulbs, etc.  Squirrels are particularly active in the fall and can tear up a lawn doing this, leaving many saucer-like craters in the lawn.  You may use a deer repellent.
