Electric Fencing for Bears
A highly effective deterrent
How does an electric fence work?
Electric fencing provides an electrical shock when an animal comes into contact with the
electrically charged wires of the fence. People unfamiliar with electric fencing often are
afraid that it will injure, permanently damage, or kill an individual or pet that contacts the fence. This is not true! A properly constructed electric fence is safe to people, pets, and bears. For electricity to flow in a system, such as an electric fence, there must be a complete and closed circuit. The electrical current must travel from its source through the circuit and back to the source. This flow only occurs when a charged wire of the fence becomes grounded.
Under normal operating conditions, an electric fence functions as an incomplete or open
circuit with repeating pulses of electricity generated by the energizer sent through the
charged wires of the fence. When an animal touches a charged wire, it grounds the fence,
creating a closed circuit. An electrical pulse travels through the animal and back to the energizer, delivering a shock to the animal. The electric shock is unpleasant but is not lethal.
However, if an animal gets caught in a fence for an extended period, it may die of stress.

WE use stun guns and tasers on children but cannot use electric fences to deter illegal immigration and drug smugglers?
