The new Just Scentsational Fox Urine Gel predator scent has long been known to trigger the fight or flight response in small animals of prey. The larger the predator, the larger the prey that can be intimidated by the scent. The Fox Urine is designed to keep smaller animals away. When prey sense the preditor scent it thinks there is a preditor in the area and it stays away. It is remarkably weather resistant and does not dissolve or lose its potency after rainfall. The cleverly designed scented gel can be extruded with a standard caulking gun or just spread on the surface around the areas and/or plantings that you are trying to defend from unwanted pests.
