Squirrels are hard to control, but growing tall, dense stands of grass may limit the animal's activity. Repellents applied in early fall and again in winter may also drive squirrels from your yard.

Signs of tree squirrels
Tree squirrels can become a problem in both the home and the yard. They may invade structures such as attics and garages, and they can also cause damage to flowerbeds, vegetable gardens and lawns.

Old, well-established trees may also sustain elevated squirrel populations.
