Bird Barrier released its patent-pending Tree-Shock system, which conditions birds and other wildlife to leave trees by shocking their feet with “a painful but harmless electrified pulse,” says the company.

The Tree-Shock is a .5 in. PVC tube with two stainless-steel wires wrapped diagonally around it. It contains a battery-powered charger that sends short electrical pulses down the wires.

The system can be attached to tree limbs via a variety of methods, including connectors, wires and fasteners. It can also be strung in between tree branches, says the company.

The device is available in 5 ft. and 10 ft. lengths and is also available in spools up to 500 ft.
