Abstract: An apparatus for discouraging an undesired animal from entering, remaining upon or returning to property. The apparatus first comprises a timer for selectively activating a sound generator at a specified interval for a specified duration. The activated sound generating device triggers an innate fear in a targeted animal by projecting one or more sounds that suggest the presence of a predator of the targeted animal, thereby causing the animal to flee or avoid that particular area. Furthermore, the undesired encroachment of an animal may be sensed by proximity sensors to immediately activate the sound generator or trigger the timing device. Further, the invention comprises a visual generating device producing a visual stimulus concurrent with the specified duration of the generated sound.
