Electric bear fences deliver a painful but harmless shock to intrusive bears. Electric fences are extremely effective and bears quickly learn to avoid the area. They are an ecological solution that prevents bears from becoming accustomed to human activity and food, protecting both people and bears. Margo Supplies provides a broad range of custom-built portable fence kits, from small backcountry camps kits to semi-permanent set-ups. We also supply the special materials to construct permanent electric fences, including solar powered energizers, lightweight fibreglass posts, and specialty hardware. Our systems have been developed through years of extensive fieldwork and testing under rigorous conditions, from temperate rainforest to the high Arctic and are designed to exclude even the most determined bear.
