The United States and Canada has experienced an explosion in deer population over the past 100 years. According to animal experts, deer populations in the United States alone are estimated to be well over 30 million mark and rising. This is a huge increase when considering that in the early 1912’s white tail deer in the United States were around 450,000. Large white tail deer population will continue to grow out of control, effecting crops, landscapes and commercial property. The deer problem has become a matter of serious concern. Deer damage to new plant growth is a serious problem in many parts of North America including Canada. White tail deer damage is expected to exceed $2 billion nationwide, not including $100 million in agricultural crop damage, more than $750 million to the timber industry.

White tail deer inhabit forest edge consuming crops and commercial landscapes. Deer prefer food sources that contain hardwood, shrub, and crops. White tail deer forage grounds to feed and include an open range, crops, ornamental shrubs, and forest. Deer forage 12 months a year to survive, primarily feeding in late spring and summer. An average deer weighing 125 to 250 pounds requires from 4,000 to 6,000 calories daily. Deer fencing is an option but deer can jump 8 feet high. This type of prevention is typically not feasible due expense and costs of maintaining fenced in areas.
