It is a device designed to eradicate plague insects and animals, preventing their reentry and to repel new infestations; suitable for being applied in both internal and closed environments such as large warehouses and industrial plants, as well as outdoors. It comprises an electromagnetic waves generator with double emitter, which combines a wave emitter with fixed antenna and other wave emitter with flexible antenna, both amplified. The wave generator constitutes a device which comprises an electric power supply, attached to a current transformer which adjusts current according to the driving circuit, rectifying and filtering means, a high frequency oscillator, a medium-frequency oscillator, amplifiers, a fixed electromagnetic wave emitter coil, a flexible electromagnetic wave emitter coil, and a low-frequency modulating oscillator. The system electric current feeds the device by means of a transformer that reduces the power of the electric current into 12 volts.
