What Are My Deer Fence Options?
You have three basic options—electric deer fences, barrier deer fences, and combinations of the two.
Let's look at electric fences first. The simplest kind is a one-wire fence with the wire typically being baited (attracting deer to it) and placed at a height of about 3 feet. Even if the deer don’t learn to duck under or leap over this wire, they may jostle it enough to pull the wire out of an insulator or do something else to neutralize the fence. Similar problems afflict multi-wire electric fences. And if one gets really determined by putting up a fence say six feet high with wires starting at 1 foot so that the deer cannot get underneath the fence, then weeds may drain power off the lowest wires, neutralizing the fence and rendering it vulnerable to penetration by the deer. For all these reasons, stand-alone electric fences should be regarded as a possible option well below the cost of a barrier fence, but one that is not fully reliable.
Another option is a polypropylene barrier fence using professional grade deer fencing, most of it made by the Tenax Corporation. If one includes the labor needed to set it up, this is quite a lot more expensive than an electric fence. And if one fails to maintain it—such as by removing fallen tree limbs and patching up small holes gnawed by woodchucks or rabbits before the deer find them—this fencing may also be penetrated by the deer. Or if a deer should decide to charge the fence head-on, no matter how strong the polypropylene, there is a reasonable chance the deer will break it. To deal with all of this, one may choose to install the best deer fence, which uses fencing made of metal hexagrid — equivalent to a stiff small-mesh galvanized chicken wire coated with black pvc. That yields a better, stronger, and longer-lasting fence, but one that is quite expensive.
To reduce costs, especially around orchards and gardens, I like the option of a combination fence. Set up a barrier fence using Tenax’s Standard (C-flex) polypropylene deer fencing. Arrange things so that you can go three feet outside this fence. Then, if the fence can’t do its job (because deer break into it, with or without the assistance of holes gnawed by small animals), install an electric fence wire three feet out from the barrier fence at a height of about 3 feet above the ground. It’s easy to see if the electric fence is working (the light on the charger tells you that), and maintenance is also easy (typically a matter of minutes). Meanwhile, the barrier fence is still intact, so the deer will be kept out. I don’t say that this offers a perfect answer, but it is an attractive option for those seeking to exclude deer with a modest budget.
