This product is made up of two microprocessor-driven systems that each forms system independently. Under the control of microprocessor, this product with an oscillating implement embedded in can produce mulriple-scanning pulse electromagnetic wave with variable frequency and mulriple frequency conversion ultrasonic. Electromagnetic wave can get rid of the pests around electrical wire and ultrasonic can dispel the pests in other areas of the room. The product sends out frequency conversion signal of ultrasonic to circumambience. Once touches objects, it reflects and permeates the room. The combining of the two waves has mulriple effects on the central nervous and hearing system of the pests such as rats, cockroachs, spiders and ants. As a result, the pests would be on the rack and agonizing or even have the symptom of swivet and twitch. Furthermore, the pests would be unable to reproduce. The purpose of driving pests away is realized as pests are compelled to escape. One unit covers up to 200 square meters and is applicable in areas of 80-100 square meters. It can be used not only in house, office, electricitydistribution houseand room equipped with communications network settings, but also in wire poor distributed areas such as convenience, dining room, warehouse and breeding yard. The power of this product is 6W.
