Of course, such a system would necessitate an appropriate technique to allow for refilling the feeders. For example, securing a feeder with a rope drawn over a pulley, would ease lowering and raising of the feeder when refilling. Avoid putting out dog food, bread, or kitchen scraps for the purpose of attracting other native wildlife such as raccoons or squirrels. Inevitably one or more bears will discover this food supply. Beehives, small livestock, orchards, and agricultural crops are best protected by electrical fencing.
Bears quickly learn to avoid electric fences once they have encountered a shock.
Keep in mind that it is best used as a preventative measure before damage occurs and before the bear has acquired a taste for the resource to be protected. Where electricity is not readily available, solar powered units may be employed. A short-term method for deterring bears consists of frightening the animal by loud noises, barking dogs, and spotlights. Again, this is a temporary measure, because a determined bear is likely to return if food items are at stake. As with most wildlife, bears should be treated with respect rather than fear, and it is best to leave them alone.
