White-tailed deer (Odocoileus virginianus) populations continue to increase, resulting in direct threats to public safety and increased agricultural losses. A variety of fencing methods are used to reduce deer presence at airports and agricultural areas. Electric fences may offer a less expensive alternative to expensive woven-wire fences. We tested an electric fence product, ElectroBraid™ (Yarmouth, N.S., Canada), on free-ranging deer in northern Ohio. We conducted both 1- and 2-choice tests, measuring deer intrusions and corn consumption at 10 sites encompassed with charged, noncharged or no fence. Mean daily deer intrusions decreased in each test when the fence was powered. When power was immediately applied to the fence, intrusions decreased 88–99%. When power was delayed for 10 weeks, intrusions were reduced 90%. When power was turned on and off within a 4-week period, intrusions decreased 57%. Mean corn consumption differed between treated (< 2–6.4 kg/day) and control sites (15–32 kg/day). Under the conditions and time duration of this test, the fence was an effective deer barrier.
