1Grandpa Gus'sGrandpa Gus's Natural Mouse Repellent Pouches, Cinnamon/Peppermint Oils Repel Mice from Nesting in Home/Cabin/Boat/Car Storage/RV/Machinery/Shed (10 Pouches)
Why we love it
Natural formula with pleasant scent
No mess or cleanup required
Lasts up to 3 months
Main highlights- Stop Mice Before They Move In: Peppermint oil overpowers and irritates mice sensory receptors, a physical response that makes treated spaces intolerable. Address any active infestation first, then place pouches to prevent mice from nesting or returning.
- Set It and Forget It for Up to 90 Days: Place pouches along walls and corners in enclosed spaces and replace when the scent diminishes. Trusted by over 15,000 5-star reviewers in homes, garages, and vehicles across the country.
- Natural Mouse Repellent for Home, Attic, Garage, and Seasonal Storage: Place in enclosed, low-airflow spaces where mice nest and travel. Covers attics, basements, garages, sheds, cabins, vehicle cabs, under hoods, ATVs, and stored boats between seasons.
- Mouse Repellent Pouches Safe for Use Around Kids and Pets When Used as Directed: EPA-compliant peppermint oil and cinnamon oil repel mice without poison, snap traps, or DEET. A humane, no-kill barrier the whole family can feel good about.
- Extra-Strength Dual Oil Formula with Peppermint and Cinnamon: Most repellents use peppermint alone. Cinnamon oil adds a second powerful irritant that intensifies the scent barrier, making it harder for mice to tolerate and easier for you to trust.
