I had high hopes for this product, as deer and squirrels tear my flower and vegetable gardens to shreds. This product works as advertised, flawlessly - BUT it does not repel so-called wild critters. Deer and squirrels initially were frightened by the sprayer action. However, the repellant odor did not deter animals from eventually taking over my entire garden.I talked to a county fish and game official; he opined that urban animals are too accustomed to man and his many exotic sounds and smells After three days or so, the deer simply ignored the spray of repellant. They are persistent pests that won't hide in terror on seeing me. Believe me I am quite scary. I am proceeding to evaluate other tactics.Bambi and his kin are safe for the moment.
