Invisible Deer Fencing: How It Works

After I posted my entry on deer fencing on February 28, I was contacted by David Davidson, president of Deer Fence Canada, who was generous enough to explain how invisible fencing works. It’s based on understanding wildlife and diverting deer away from the garden.

Deer can jump 14 to 15 feet high if they can see the top of whatever they are leaping over. The top of the virtually invisible fence is black in color. Deer have poor depth perception and cannot see the top of the black fence. As the deer approach the fence, it only becomes visible to them when they are 6 inches in front of it. Then they look up and, as far as they are concerned, the fence appears to go up forever and so they are dissuaded from jumping.

Every roll of fencing sold includes a package of white ribbons. These are tied onto the fence wires at deer eye level all around the fence. When the deer nudges the fence, the white ribbons move. To the deer, this signifies a deer’s white tail going up - which is an alarm signal. The deer then goes off to investigate.

This process trains the deer to walk around the fence rather than attack it. Because they are creatures of habit, they soon get the message and create a new deer trail around the fence. In wooded areas, it is recommended that a three feet wide clearing be created in order to facilitate installation of the fence. This cleared path becomes a new route for deer to explore.

The invisible deer fence makes it possible for us to successfully co-exist with wildlife, live in greater harmony with nature and protect an investment in landscaping.
