Grandpa Gus's Potent Mouse Repellent Spray is made from natural Peppermint and Cinnamon essential oils. No harsh chemicals, glue traps, or rat poison. A natural and effective solution to deter mice, rats and other rodents from invading your home/cabin, machinery, boat/car storage, RV and shop, building nets or chewing on wiring. Spray in cupboards, vehicle cabs, under the hood of your car (vehicle wiring and vents), RVs, garages, crawl spaces and storage lockers, under your sink, garden sheds, around plants, in cabinets and tool boxes, and anywhere you've seen mice. Grandpa Gus's formula uses 7% peppermint and cinnamon whereas most other repellents use less than 1% of peppermint concentrate only. Its water-based repelling formula spreads faster than non-scientific formulas. It also leaves no stains. Up to 1240-sprays.
