Electric Bear Fencing

Posted by Leanne Smith on

 An electric bear fence is a psychological barrier that keeps farm animals in and wild animals and vermin out-even over long distances and is the most effective method of non-lethal bear security management.  Electric bear fence systems have the power to keep these animals out of landfills, apiaries, Orchards, berry fields, vineyards, work camps, cabins, campsite, livestock enclosures and birthing grounds, grain crop or storage, and just about anywhere else you don't want bears to go. This style of fencing can also add a higher level of security to any property.

Electric Bear fencing is relatively easy to maintain and economical to build being only a psychological barrier it doesn’t require great strength to be effective. However, it must be well designed and constructed to absorb some pressure from animals, snow and wind. The energizer must have enough power for the length of the fence and for the animals being controlled. More power is better than not enough. For areas of high attractions or habituated problem bears we recommend a minimum of a 2 Joule energizer  

How an electric fence works is a pulsed electric current is sent along the fence wire, about one pulse per second, from an energizer which is earthed. When the animal touches the fence, it completes the circuit between the fence and the ground and receives a short, sharp but safe shock. The shock is sufficiently memorable that the animal never forgets.  If one is using an electric fence on grounds that are poor conductors such as sand, gravels or rock than it is best to use a positive/negative electric fence system. This is when wires are hooked up alternated positive and negative (hooked directly back to the ground side of the energizer) thus ensures that if a positive and negative wire are touch simultaneously than the bear receives the full shock of the energizer. With a poor earth ground return a bear may not receive a powerful enough shock to deter them.  


There are two basic types of fence design permanently and temporarily portable. For longer term installations like landfills, transfer stations, work camps, horticultural fields, professionally designed permanent type fencing is recommended.

Permanent Fence Configuration - Bear

There are an array of permanent electric fence designs that can deter bear. Bear fencing is often used to protect beehives, dumpsters, lambing and calving areas, corrals and other small areas in need of protection form scavenging or predation.

Portable Electric Bear Fencing

For areas of short term or seasonal protection Temporary portable type electric fencing systems are best utilized. FenceFast has a range of portable and semi portable systems and can help with customized systems if required.

For commercial Apiaries situations with beehive larva being a very high attractant to bears we recommend a minimum of an 2 joule energizer to ensure there is a strong enough shock to deter a bear first shock. In the case of lower level bear levels or just a few backyard hives a positive negative setup with an 0.50 Joule energizer would be a minimum. Note in Canada all in one solar energizers do have limitations in later in the season fall in more northern and mountainous areas. In those areas we would recommend an energizer with a plug in charging option in case the batteries need to be topped up in less than favorable solar conditions

  2. The Predator/Bear positive/negative exclusion Netting 50m is a very effective method to excluded bears and even small vermin. To complete this system just match it up to an energizer and a ground rod. A single reel connector is a required to hook up the negative (grounded) side of the system.
