Squirrels are never found far from the shelter provided by trees. They are opportunistic foragers feeding on acorns, nuts, fruits, berries, corn, fungi, flower bulbs and birdseed. They readily adapt to suburban and urban areas.
Chasing a frantic squirrel inside your house can result in additional damage. If a squirrel is trapped, open a door or window, block off the room it is in and quietly wait for the squirrel to exit. Once the squirrel is gone, identify where the squirrel entered and seal the access. If the squirrel is in the fireplace, close the damper, block off the room and open an exterior door or window to provide an escape route for the squirrel.
Squirrels trapped inside the chimney flue can be freed by closing the damper and lowering a 1/2-inch diameter rope into the chimney from the roof. The rope must be long enough to reach down to the damper. Anchor the upper end and wait for the squirrel to climb out, then cover the chimney. Before evicting a resident squirrel from the attic determine if young are in the nest and where the female's entrance is located. If there are no young, scare the squirrel out by banging on the rafters inside the attic or wait until the squirrel leaves for the day.
Seal the entrance with 1/4-inch hardware cloth or with sheet metal. Extend the seal at least six inches beyond the hole. If young are present, locate the entrance and install a one-way door until all have left the nest, then proceed as previously described.
