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). The long-lasting formula is okay to use around kids and pets when used as directed. To use, attach your garden hose tightly to the bottle’s sprayer head and adjust the nozzle to the ON position. Ensure the water supply is on and turned to full pressure. Then, spray in designated areas at a rate of 1 quart per 10,000 ft. One bottle of Mole and Gopher Repellent covers up to 10,000 sq ft.
