Fence Information

 What is Deer Fencing?


Dave and Al Benner  started Benners Gardens in 1992 after proving the system on David Benners Moss Acres gardens.The mesh used is still manuafactured by Tenax as C Flex. In 2005 Deer Fence Canada Inc. teamed with Benner's Gardens to provide the same solutions to Canadian customers from our base in the nations capital,Ottawa. 

( note Dave and AL Benner have long since retired, the company  they started, Benner's Gardens has been sold twice since and the present owners have taken the company in a new direction.)


Quality of our products

Tenax C-Flex is manufactured from the finest polypropylene materials and has UV stabilizers and anti-oxidants added to ensure the longest life for the products (possibly as long as 20-25 years). Tenax C-Flex deer fencing is extruded in such a way as to provide a unique combination of incredible strength, invisibility, and workabilty. Tenax C-Flex P is our heavy duty deer fencing with more polyproplene making it stronger.




Ease of installation.

Our company also offers a complete "system". Our wide range of accessory products, including post inserts that eliminate,concrete post setting, digging holes or standing on ladders, ready to assemble access gates, easy to work with nylon reinforcement cable, and several time and labour saving installation tools, make each project much easier to complete in a timely and aesthetically pleasing manner.We have enhanced the original Benner's Gardens fence system to withstand the rigours of the most severe Canadian weather.

All our products are easy to install with the simplest of tools.



Unmatched support and customer service.

Most importantly, our organization also offers in-depth technical support. After many years of taking on the deer and winning, we have lots of valuable information to share.We can help you plan your installation. We can even estimate your total length of fence interactively online with the aid of Google Earth, Autodesk Maps or other online mapping technologies. We also provide a step-by-step detailed installation instructions with every order.  We have a range of sizes of  Deer Fencing for you to choose from including our Standard Deer Fence (Tenax C-Flex), Heavy Duty Perimeter Deer Fence (Tenax C-FlexP), and installation materials.


Tenax CFlex  Deer Fencing is a high-strength, wire fence-like mesh (1.75 inch) material constructed of UV stable black polypropylene. This "hi-tech" plastic fence is 7 ½' feet high, cost-effective, easy to install, and provides long-term deer protection without changing the appearance of the property.

The ultimate installed height of the fencing is approximately 7'. Six inches of the plastic fence grid is "flared" out onto the ground away from the protected area to keep deer from pushing underneath the fencing. For over ten years now this height has proven to be sufficient. Because deer have poor depth perception and cannot see where the fencing actually stops; they are fearful of jumping it (when pressed, whitetail deer can jump over 10'). In fact, when our Deer Fencing is first installed, white flagging streamers (included) need to be temporarily tied to the fencing every 10 feet so the deer do not run right into it.

Unlike electric or wire fence, our deer fencing can be easily attached to existing trees (up to 20 - 25 feet apart). In areas where trees are not present, galvanized steel pipes (baked on black finish) can be installed for support. The fencing is also staked to the ground with ground stakes every five to six feet to keep the deer from pushing underneath it.

Heavy Perimeter vs. Standard Fencing

In the past, many large perimeter garden fences were constructed from unattractive and cumbersome electric or wire fence. In order to offer additional strength for these larger projects, working with Tenax Benner's Gardens introduced its' second generation deer fencing in the spring of 1996. "Heavy Perimeter Fencing" is very similar in design to our Standard Fencing, but is 65% stronger and was created specifically for enclosing areas larger than one-quarter acre, or for locations with high deer pressure or deer paths.The mesh is approximately 2 inch squares.


Heavy Perimeter Fencing has been designed to provide added strength for enclosures that are large enough that the deer don't easily realize that they can just walk around the protected area. For these larger enclosures, the concept of re-directing or "training" the animals to keep them out of the protected area is by itself insufficient, and our Heavy Perimeter barrier is required. The larger the area you are enclosing, the more you are changing the deer travel patterns, thus the greater the risk of them inadvertently running into the virtually invisible wire-like plastic fence.

We have had reports of large bucks bouncing off our Heavy Perimeter fencing when accidentally colliding with the newly installed system at full speed. Virtually all enclosures over 1/4 acre are now being protected with Heavy Perimeter Fencing with two black nylon tension cables (at the top and 3' off the ground - the "impact zone"). The only exception is the west coast, where the less aggressive/smaller Black Tail Deer pre-dominate. In this region it is possible to enclose considerably larger areas with the standard deer fencing.

Although deer running into our fencing has been an infrequent occurrence,

it has typically happened in more heavily developed areas where there are large numbers of animals, and the deer have been frightened by dogs, cars, or other means, and blindly run in a panic. Many suburban metropolitan areas where no hunting takes place, are currently experiencing excessive pressure, and will benefit from the heavier deer fencing. With either of our plastic, non-electric wire fence-like materials, once the deer have been properly trained, they will re-direct their paths and avoid your property entirely. The key to successful deer damage prevention is total enclosure of the area to be protected. If this is not done, deer will wander the perimeter of the fenced area until they find an opening, enter the property, and become trapped inside. Note: It is important to mention that in moderate to high-pressure deer areas we have repeated reports from electric fence users that the deer are "diving" between the wire fence strands and ignoring the mild shock to gain access to the enclosed area. In these situations, many people will actually run our high-strength plastic fence grid right behind the electric wire fence, often attaching to it directly with fence ties.

We are always available to answer any questions about how to make our deer fencing work on your property. All orders come with easy-to-follow installation instructions. You can also call us at: 1-866-913-DEER with any technical questions you may have while installing you Benner's deer fence.
