An autonomous drone integrated with wide bandwidth, high energy acoustic wave generators sent to evict and eradicate agricultural pests within a patrolling area. The drone hovering close to a plant bombards its leaves and fruits with high energy acoustic waves via frequency and tone determined by an onboard synthesizer through acoustic power amplified to drive the sideways and bottom mounted acoustic wave generators. Agricultural pests such as caterpillar, beetle and the like are bombarded with powerful acoustic waves causing their bodies to vigorously vibrate and resonate with synthesizer frequency to dislodge or kill the pests. Other insects such as moths are forced airborne by a propeller's strong downdraft and are electrocuted by integrated high voltage screens. Inside a hotel room, the drone hovers close to a surface of a bedding mattress, bombarding the surfaces with powerful acoustic waves tuned to frequencies that cause bed bugs to resonate and die.
