Grandpa Gus's Rodent Repellent Spray Super Concentrate is a plant-based indoor deterrent built on peppermint and cinnamon oils instead of poisons or harsh chemicals. A 4 oz bottle of concentrate mixes with water to make up to a gallon of ready-to-use spray, which you apply along cupboards, entry points, wiring, and stored vehicles to keep mice from nesting and chewing. It suits homeowners and cabin, boat, or classic-car owners who want a low-toxicity barrier and are willing to reapply, since essential-oil repellents fade faster than traps or baits. Unlike snap traps and poison blocks, it kills nothing and needs repeated use to hold a line.
