This range of ultrasonic frequencies can irritate and interfere with the brain and auditory nervous systems to quickly and powerfully drive away from most types of pests. The output pattern of the antennal motor neurons has rarely been recorded for insect species probably because of the difficulty to generate their activities under the physiological experimental conditions.
