FIELD: in-house pest control. SUBSTANCE: device has gate, voltage-controlled generator, which output is connected to input of amplifier. Output of power amplifier is connected to high-frequency acoustic emitter. In addition device has external programmed memory unit, single-crystal microcomputer, analog-to-digital converter. In addition device has second gate, second power amplifier and low-frequency acoustic emitter. Depending of program stored in single-crystal computer, it outputs sequence of codes which enter low-frequency or high-frequency acoustic emitter through digital-to-analog converter and first or second gates. EFFECT: increased efficiency of device operations due to possibility either attract rodents or to scare them off. 1 dwg
