University Studies have proven that our technology delivers more powerful protection than other brands hands down! Our brand outperforms other brands by effectively repelling deer and rabbits from landscapes, gardens, flowers, shrubs, trees and vines. Our product contains more powerful and active ingredients than other leading repellents. Unlike other repellents, Nature's Mace uses a "scent and fear technology" that has been proven to be more effective than other methods, such as the "taste method". Our Technology is simple. By researching the top leading deer and rabbit repellents, we were able to isolate the active ingredients that make these other products effective. We increased the potency, and combined these ingredients into one "super power" deer and rabbit repellent.
