Victor Mole and Gopher Repellent repels moles, voles, and gophers from lawns and ornamentals. The active ingredient is 100% castor oil - when soaked into soil it works to contaminate the moles underground food source (earthworms and grubs). To use, attach your garden hose tightly to the bottle's sprayer head and spray in designated areas. One bottle of Mole and Gopher Repellent covers up to 10,000 sq ft. The long lasting castor oil mole repellent can be used around children and pets when used as directed.
