FIELD: agriculture.
SUBSTANCE: invention relates to means of controlling rodents, mainly rats and mice. Ultrasonic security and protection deratization system for repelling rodents, which forms protective ultrasonic field, includes control unit (12) and remote active ultrasonic radiators (13). Active ultrasonic radiators receive power supply voltage and control signals from the control unit via wire communication lines (11). Generation of ultrasonic signal takes place directly in remote active ultrasonic emitters.
EFFECT: increased efficiency of device operation.
