A Harmful wild animal repelling device of the present invention comprises: an approach detecting module (200) which include an approach detecting module control unit (201), a transmission unit (202), and a sensing unit (203), and in which, when a wild animal comes in contact with a sensing unit, an approach detecting module control unit (201) is converted from a sleep mode into an awake mode and wirelessly transmits own address (ID) to a server module (100) through a transmission unit (202), and when the transmission is completed, the approach detecting module control unit (201) is converted into a sleep mode； a server module (100) which includes a server module controlling unit (101), a communications module (102), and a storing unit (105), and in which, when a communications module (102) transfers a signal received from an approach detecting module (200) to a server module controlling unit (101), a server module controlling unit (101) stores data at a storing unit (105), and wirelessly transmits, through a communications module (102), an address (ID) and a light emitting diode (LED) motion pattern of a repelling module (300) which is related to an approach detecting module (200) of a corresponding address； and a repelling module (300) which includes a repelling module controlling unit (301), a receiving unit (302), and a LED unit (303), and in which, in case a repelling module controlling unit (301) receives own address (ID) through a receiving unit (202), a repelling module controlling unit (301) drives a LED unit (303) according to a received LED motion pattern. According to the present invention, when an approach detecting module detects an approach of a wild animal, an approach detecting module transmits a wireless signal to a server module. Consequently, a server module transmits a wireless signal to a repelling module near the corresponding approach detecting module, and a wild animal is repelled by a LED light or a speaker sound.본 발명의 유해 야생동물 퇴치장치는 접근탐지모듈제어
