    IPM Recommendations

    • 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.
