PROBLEM TO BE SOLVED: To provide a small animal-repelling device which emits light and generates supersonic waves to repel small animals without using a chemical agent. SOLUTION: This small animal-repelling device is characterized by comprising a sensor for detecting the approach of a small animal, a sound-producing circuit for producing a sound in response to the sensor, and a light-emitting source for emitting light by an activation from the sensor.
