I Must Garden mole and vole repellent is an environmentally safe, humane and effective way to deter burrowing animals from digging and destroying your garden, lawn, plants and landscaping. We created the strongest mole and vole repellent on the market by combining a super strong 20% castor oil formula with botanical oils that taste and smell bad to moles and voles and other burrowing animals. The proprietary blend of oils safely coats their food source (grubs, worms, roots and more) and makes treated areas highly unpleasant forcing pests to relocate. There are no poisons, harmful chemicals or toxic glues in our products. All of our repellents are safe to use around children and pets and are completely biodegradable. The granular repellent is easy to apply by hand or with a spreader. Our granular mole and vole repellent is one of most popular formulas, being granular application is extremely flexible, making it perfect for most homeowners.
