Grandpa Gus's Mouse Repellent Pouches use an extra-strength blend of peppermint and cinnamon oils to naturally help repel mice and discourage them from nesting in enclosed spaces around your home and property. The dual-oil formula creates a powerful scent barrier that overwhelms mice's sensitive senses without the use of poisons, snap traps, or DEET, providing a humane, no-kill solution that is safe for use around kids and pets when used as directed. Ideal for attics, basements, garages, sheds, cabins, RVs, boats, vehicle cabs, under hoods, seasonal storage, and other enclosed, low-airflow areas where mice are likely to nest or travel. For best results, address any active infestation first, then place pouches along walls, corners, and entry points to help prevent mice from returning. Each pouch provides long-lasting protection for up to 30 days and should be replaced when the scent begins to fade. Trusted by more than 15,000 five-star reviewers, Grandpa Gus's Mouse Repellent Pouches offer an effective, natural way to help keep your spaces mouse-free.
