The first is it can be highly effective if installed by a professional who understands deer and knows how to use the fence as a deterrent. Electric deer fencing is effective because when the animal comes in contact with the shock, it then tries to avoid it in the future. To insure that the deer do come in contact rather than just leaping over the top, Mr. Rickertt says they install the fence at a 45 degree angle. Deer have poor depth perception and avoid a less vertical jump because they can't see what is beyond. Mr. Rickertt also said that this is the time of year to be particularly attentive to deer prevention as the deer are eating more.
