    Deer Fencing Still Rates Highest in Deterring Deer

Despite the reduction in deer herds this year, deer grazing still presents a substantial threat to your trees and landscaping. Deer damage to ornamental shrubbery and landscaping is projected to exceed $500 million this winter. Deer not only graze in neighborhoods during the winter when natural plants are scarce,but bucks also rub their antlers against the bark of trees damaging or killing them. Even if you have just a few deer that regularly travel through your property, each deer requires 3% of their body weight in food per day to survive. That amounts to between 5 and 10 lbs of green foliage per deer per day. When you consider the weight of tender leaves, buds and spring flowers in your yard, a small herd can completely devastate your landscape gardening.

Deer Repellant Sprays

Non-invasive solutions such as sprays containing capsicum or hot pepper, raw egg and garlic urine and other ingredients have been popular because spraying is the least invasive solution. Not only are these sprays expensive ($20 to $30 per gallon), but the spray must be reapplied every few weeks and after rain or snow falls in order to remain effective. If you miss an application, you may be surprised to find your arborvitae bushes gone. Dial soap also has a smell that respells deer. You can drill a hole into the soap bar and then hang it with fishing string. These smell based deterrents are usually less effective as the winter progresses because deer become more hungry as the food supply is covered with snow or is depleted.

Deer Sound and Motion Detectors

Other solutions like ultrasonic sound waves, motion detecting lights are completely ineffective after a period of time for deterring deer. They simply become used to it and ignore the deterrent.

Mesh or Chain Link Deer Fencing

The Pennsylvania, Maryland and Virginia Departments of Natural Resources all recommend eight foot deer fence as the most effective way to deter deer. The polyethylene mesh mounted on black metal posts must be at least 7 feet to work reliably. If zoning limits fence height to 6 feet, chain link fencing may also be used; however, deer can easily jump over fences shorter than six feet.

Electric Deer Fencing

Another alternative is five foot high-tensile wire fence with an electrical charge, like fence used in agriculture. This fence works well in larger yards and fields where no children play. A UL energizer charges the fence with 6,000 to 7,000 volts that slightly shock the deer. In general, deer learn after three shocks to take another path. The electrical fence requires a five to seven foot area to be cleared to prevent shorts. Since deer require three reinforcing shocks, it is best to bait the fence with apples or peanut butter to teach them early in the season to take an alternate path.
