Kiwi Fence School
Every farmer knows the value of a good fence. High Tensile Fences are less expensive, more durable and more effective for containing and protecting livestock. Now you can learn to build one of the best fence systems available from the people who introduced High Tensile Fence to the United States.
Anti-Deer Fence
The 3 major styles of Anti-Deer fencing are:
  1. High Tensile Woven Wire Barrier Fence: An 8’ high fence can be built using 8’ fabric. This method 98% effective. Class 3 galvanized wire can be expected to last 15–30 years. Bracing for this style fence consists of two 14’ x 7” posts with a 16’ x 5” horizontal post. Line post may be all 12’ x 4”-5” or 10’4” Tee posts provided that a 12’ X 6” Line Boss post is used at a 4 to 1 ratio.
  2. Pennsylvania Anti-Deer Fence: This vertical, High Tensile electric fence is a proven deterrent to deer and is effective in a 5 or 6 wire combination. It is 2/3 less expensive than the 8’ woven wire fence but requires slightly more work to ensure that an electric charge greater than 5,000 volts is maintained. Because deer choose to crawl under or step through a fence rather than jump over it, the spacing of the wire is critical. The bottom wire should be 8” to 10” above the ground with additional wires at 10” to 12” spacing to be effective. This is a permanent fence with a 15 to 30 year lifespan. It is constructed with Max-Ten 200 (200,000 PSI, 12 1/2 gauge) and the corresponding accessories necessary to maintain 250 lbs. wire tension. The same construction techniques apply as outlined in the “KIWI DO IT YOURSELF HIGH TENSILE FENCING” guide. The wire spacing and post height are the key here. The 5 wire spacings are 10”, 12”, 12”, 12”, 12”. The 6 wire spacings are 8”, 10”, 10”, 10”, 10”, 10”. Both are on posts with 60” set out of the ground. The 6 wire fence can be constructed with a ground return system, which allows for greater control of the electrical charge on the fence when encountering extreme changes in climate during the year. This fence also needs a 10' clearing the entire perimeter of the fence. Its also recommended to bait the fence. The success of this system is based on owner maintanence. Approx 75 to 80% effective.

    Another variation is the 7 wire slanted electric fence, which has proven effective for larger acreages. This fence is constructed in much the same way as the vertical fence but slants outward to present the deer with a more effective two–dimensional barrier.
  3. Spider Electric Fence System: This 16.5 gauge fence system is now available to do the same, or better job, for less cost still. It can be classified as a temporary fence and may be easily moved or resized as agricultural needs change.

    In the Spring of 1987, Art Selders, Ag Engineering Specialist of West Virginia University, selected four sites to measure the effectiveness of the SPIDER Electric Fence System in excluding deer. A vineyard, large strawberry growing area, vegetable garden and a nursery, (all having suffered extreme deer damage in the past,) were chosen. Since that time, SPIDER has been proven an effective deer deterrent. In 1980, Penn State University began testing the Kiwi Anti-Deer Fence, with 5 wires, later to be known as the Penn State Five Wire. Kiwi Fence continued their research on the larger white tailed deer and added a sixth wire for effectiveness. Now, Penn State University has selected the five wire SPIDER Fence (11,000ft.) to exclude the deer from 160 acres of their Horticultural Experimental Station.

    You will notice from the specifications that the height of this anti-deer fence has been lowered by about 12". As the deer are not readily jumping the 12 1/2 gauge 5 and 6 wire anti-deer fences, we can indeed lower the SPIDER fence and still maintain the same effectiveness.

    Material and installation to build a 4 to 5 wire SPIDER fence is less expensive than either the material or labor cost of the 12 1/2 gauge anti-deer fence. When one takes into account the higher material cost when building the Kiwi Anti-Deer Fence, particularly around small acreages, the SPIDER System is much more attractive.

    The SPIDER System uses a special 16 gauge high tensile fence wire. With the knowledge that deer have some difficulty with depth perception and are confused by the 12 1/2 gauge wire, the thinner 16 gauge wire appears to confuse them even more. Unlike the higher tensioned 12 1/2 gauge wires, at 250 pounds per strand, that occasionally allow deer to slither through, SPIDER Fence can "roll with the punches", meaning that because of their lighter tension, the wires will travel or stay with the body of the deer longer, administering the powerful electric shock. This gives new meaning to an electric fence.

    As each week goes by, we are seeing more and more farmers and orchardists installing our lower cost SPIDER fences to help stop the deer that are eating them out of house and home. At last, there is a more practical, low cost fence offering reduction in deer damage and penetration!

Do's and don'ts
  1. Position the anti-deer fence line at least 5' away from old fence rows or brush lines.
  2. The wires must be electrified upon tensioning, so set up the electric fence energizer first.
  3. Any gates should be left open for up to a week in order to assist training the deer. This will allow any deer to exit rather than force them through the fence.
  4. Use only approved crimping sleeves for attaching and joining wire rather than tying knots, thus maximizing the wire strength as well as obtaining a perfect electrical connection.
  5. For maximum current flow, join all hot wires and optional ground return wires together at each end of each section of the fence.
  6. Properly ground the un-insulated top wire for each section of fence in the middle. Also, follow this procedure below any over-head electric wires.
  7. Only use pressure treated round southern yellow pine posts treated to AWPA C-16 and assayed to standard C-4. No more than 1/3 of their diameter should show white un-treated wood (heart-wood).
  8. Install only approved lightning arrestors near the energizer and at the ends of the fence line. They should also be placed at the major high point of the fence line. A Kiwi lightning choke should be installed at the energizer.
  9. To confuse the approaching deer this fence should not look like a physical barrier. Do Not use any form of droppers™, battens or spacers.
  10. This fence is not a multi-purpose fence, eg; boundary, security, property identification etc. It is designed as an anti-deer fence only and will repel deer from airport run-ways, vineyards, orchards, and minimize penetration where they would normally feed.
  11. To ensure a correctly built anti-deer fence system, have only certified high tensile fence professional installers contract the installation.
  12. Insist on a 3-hour maintenance training program after the installation has been completed to fully familiarize staff with the concept of this fence.
  13. Spray herbicide in a 12' width under the fence in early spring to maintain voltage at a minimum 4000 volts.

With electrical fencing of any design it is important to remember that:

  1. A quality energizer that delivers a minimum of 5,000 volts is a must.
  2. High Tensile fences require strict adherence to construction guidelines (i.e., corner assembly, wire configurations and maintenance).
  3. Cost of construction decreases with increasing size of the plot to be fenced.
All of these styles of anti deer fences have their advantages such as cost, installation and maintenance. Kiwi can help you make an informed choice.
