This all natural Groundhog Repellent is an easy to use spray that works best and lasts longest on dry plants, and should be allowed at least one hour to dry before watering or rainfall. During heavy rainfall, or if you have an extensive groundhog problem, more frequent applications will be necessary. Spray your plants with a fine mist and repeat the application as necessary (usually every 1-2 inches of new plant growth). You may also saturate the ground and the holes to prevent the animals from re-entering and making their tunnels unpleasant. Ready to use 32 oz. trigger spray bottle covers up to 1,000 sq ft.
