Adult squirrels can cause significant damage gnawing to get back inside to their young. Remember that live-trapping is not a final solution. Be sure to close all possible access areas to prevent repopulation. Prune overhanging tree limbs, shrubs, and vines that may provide access to attics and other areas. Cover telephone and electric wires near the house with long plastic tubing to discourage use of the wires for entrance and exit.
Squirrels are excitable and can cause severe damage if trapped inside a home.
When badly frightened, they tend to run recklessly in circles and will knock over anything in their way. Quickly and quietly open a door or window to the outside and leave the room. The squirrel wants out as much as you want it out and will leave as soon as the threat of your presence is gone. A squirrel may fall in a chimney while climbing on the roof. Do not remove the squirrel through the fireplace as it may escape into the room.
