An insect repelling system utilizes a vehicle, and includes: a position information acquisition unit configured to acquire and provide vehicle position information, an interface unit configured to display species-based frequency ranges that insects avoid and to allow a user to select one of the displayed frequency ranges, a controller configured to perform control such that the interface unit displays the species-based frequency ranges that are avoided by insects that can be repelled at the current position of the vehicle based on the vehicle position information acquired by the position information acquisition unit and to generate and output a control signal for outputting a sound having the frequency selected through the interface unit, and a sound generation device configured to output the sound having the frequency by the user according to the control signal output by the controller.
