SafeRacks 2'D x 6'W x 7'H Garage Shelving Unit - White - Steel Garage Storage Rack 500 Pounds Per Shelf

Ultrasonic Pest Repeller products use the advanced ultrasonic technology to kick that nasty pest out of your homes. It is capable of forcing away all kinds of insects, rodents, cockroaches, spiders, roaches, ants, mice & rats effectively on their nervous and auditory system, irritating them and forcing them to run away to give you a pest-free home. We recommend plugging Ultrasonic Pest Repeller vertically and 10-15 inch away from the floors or counters so that the ultrasound can attack and control pests. The installing point should be avoided from carpets, curtains, or attaching sound materials. Decreasing sound pressure may reduce effects of the device. It is extremely easy to use. Just plug the ultrasonic pest repeller into the AC220V (or 110V) power socket. (Power range: AC90V-250V, Frequency: 50-60HZ)
