Exclude squirrels by blocking entrances into buildings with hardware cloth.
Keep squirrels from climbing trees by installing a 2-foot-wide collar or metal 6 feet off the ground around the tree, or using 2 foot sections of 2-3 inch pipe over utility lines (consult the electrical company for assistance if placing sleeves over electrical wires).
Use live traps to remove squirrels from buildings, seal entry points and then release outside. Lethal traps are also available for squirrel control.
