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 hose end repellent easily connects to any outside hose bib and makes application fast and easy. Hose end sprayers are know for being quick and convenient. Customers should take into account the time of year and their location when choosing between liquid or granular. Colder temps can make it more difficult to spray with a hose due to the thickness of our mole & vole repellent. As a tip: warm it first by leaving it in the sun for awhile or putting the container in hot water before spraying.
