I Must Garden Mole & Vole Repellent is used to rid moles and voles from lawns, gardens, flower beds, and more. It works by making the food source and environment of burrowing animals smell and taste unpleasant. This causes the animals to leave the treated area in search of a better habitat. Our repellent contains all natural ingredients that can be used year round. I Must Garden Mole & Vole Repellent is people and pet friendly and safe for the environment too!
