The only high-powered ultrasonic pest repeller with special "Multiplex Modulated Sweeping Ultrasonic Sounds" designed and manufactured by us. These high intensity ultrasonic sound waves (20~65KHz) are out of the range of hearing of humans are most household pets, but pests. These nerve-crushing sounds ( to rodents and insects) directly penetrate their brain and nervous systems causing them severe pain and discomfort, and make them uneasy and act abnormal-such as to become frantic jumping, stampeding and fighting each other, which result in the voluntary repulsion against ultrasonic wave areas and pests are impossible to stay at such radiated areas.

The proper ultrasonic wave causes great pain and discomfort to pests. It repels pests by generating direct, continuous and various waves to stimulate their central nerves.  Pests can hardly stay under this environment.

• ELIMINATES MOST PESTS AWAY --- It changes the frequency of emitting waves 1 - 60 times in a second automatically to assure the complete coverage of almost communication frequencies of rodents insects and many other pests. And make them not get used to the ultrasonic waves.
• SANITARY AND SAFE --- It eliminates pests by generating ultrasonic waves. More sanitary and economical than chemical poison method. It is no harm to human beings and any other animals. It’s also no pollution to environment.  
• HIGH EFFICIENCY, WIDE RANGE PERFORMANCE ---The high power emitting of ultrasonic waves drive pests away for  wide range ( 3 – 6 meters in diameter ). 
• NO INTERFERENCE TO ELECTRIC APPLIANCES --- It will not interfere with any electric/electronic appliance such as home/car burglar alarm, fire or smoke detector, radio, television reception, microwave oven, electro-magnetic oven, computer, cordless phone or cellular phone.
• THE MORE LONGER YOU USE, THE MORE EFFECTIVE IT IS --- The obvious effects appear in 2 – 4 weeks after the installation. The continuous use will prevent further nesting and inhabitations.

• It generates ultrasonic wave and ionic. Not only it repels rats and rodents, but also creates a stream of healthy negative ionic which pull pollutants and bacteria out of the air before they reach your lung.
• The negative ionic is healthful for human beings and household animals.
• The effective range is about 2,500 square feet.      

• Homes especially at kitchens.
• Computer rooms.
• Hospitals, clinics.

• Books houses.
• Shops, stores.
• Classrooms.
