Bird-X Yard Gard YG Ultrasonic Animal Repeller, Ultrasonic, 6-3/4 in L

The Bird-X Yard Gard™ is the result of decades of scientific study and field testing. It's the scientifically proven, best selling ultrasonic repeller useful against deer, raccoons, skunks and other small animals. It creates an ultrasonic sound wave that repels these pest animals without chemicals, traps or poisons while still being silent to most humans. Set it to continuous use or motion-activated mode and keep pests away. The yard gard has a motion-sensor setting along with the standard, continuous setting. The yard gard is weather-resistant and fully programmable. The convenient and flexible coverage makes it perfect for small residential spaces like balconies or patios. Use with included power cord or supply your own "C" batteries (4 x 1.5 V) for a cordless device.
