You can purchase the different components to build a vertical electric fence at most farm co-ops or feed stores. On a technical level, this involves linking a few “polytapes” (or a number of metal wires with a diameter of 1/10 inches, 12.5 AWG) on posts spaced every 33 feet. The wire must be attached to the post by a plastic insulator, and the electrical current circulating must have a tension of at least 4000 volts. (More is ideal; 8000 volts will prevent deer from knocking the fence over at night.)

Polypropylene trellises designed expressly for guarding against the entry of deer, raccoons, hares and other wild animals are sold by Dubois Agrinovation of Saint-Rémi, Quebec. 1-800-667-6279. www.duboisag.com
