ABSTRACT:
A mole chaser with improvements in the construction and method of audio frequency and vibration generation includes a main stem, a cap, a battery chamber and a control circuit board, suspended or loosely installed inside of the main stem to make constant contact with inside wall of the main stem, which has a buzzer mounted thereon for generating audio signal to chase away underground rodents, such as moles. The audio frequency produced by the energized buzzer will cause the resonance to circuit board to make it vibrate and strike the main stem to produce more low frequency noise and vibration to enhance mole-chasing effect.
