Home of the Grizzly Guard — a certified bear-resistant composting solution. Designed and rigorously tested in Jackson Hole, Wyoming, the Grizzly Guard was developed by Robb Sgroi, who brings over two decades of experience in natural resource stewardship. Robb set out to solve a common problem for home composters: keeping food waste secure from wildlife. The result is a durable, effective composting system built to protect your compost — and the bears.
