A rodent repellent assembly for inhibiting rodents from chewing electrical wires of an air conditioner includes an air conditioner has an exterior wall being comprised of a ferromagnetic material. An ultrasonic emitter is provided which emits ultrasonic sound waves when the ultrasonic emitter is turned on to repel rodents. A pair of magnets is each coupled to the ultrasonic emitter. Each of the magnets magnetically engages the exterior wall of the air conditioner for mounting the ultrasonic emitter to the air conditioner. In this way the ultrasonic emitter inhibits rodents from chewing on electrical wires of the air conditioner.

Certain types of fish respond differently to certain stimuli than other types of fish. Particularly, predetermined sound or vibration can cause certain types of fish to move away or jump. These reactions by particular types of fish can be used to capture the fish or prevent them from accessing parts of water systems. An exemplary capture mechanism employs multiple receptacles adapted to catch jumping fish from the air. An exemplary barrier of directed sound can prevent fish migration.

Embodiments of the present invention provide a novel deterrent barrier based on the phenomenon of fluid cavitation. A drive unit comprising a motor and a propeller are configured for inducing cavitation in water. The cavitation takes the form of a rotationally confined vertical column of cavitation bubbles extending from the propeller, and a one-dimensional series of drive units spanning the width of a waterway may provide an effective, environmentally friendly and non-lethal barrier against entry of target fish species.

A wave transmission control device to control a transmitter to form a sound field in water includes processing circuitry to, when detection information is input from a sensor to detect an organism in water, determine a characteristic of the organism and a distribution state for every characteristic using the detection information, to acquire sound information based on the characteristic by referring to a database in which a characteristic of an organism and sound information are associated with each other, and to determine a sound output condition in such a manner that a distribution state changes from the distribution state which is set for the characteristic received before processing starts and to cause the transmitter to output a sound based on sound information using the output condition.

A system for a pest deterring device including a barrier assembly, an ultrasonic assembly and a structure assembly is disclosed. The barrier assembly includes a barrier that has a rectangular triangular shape. Within the barrier is an ultrasonic transmitter that generates and emits ultrasonic waves. The ultrasonic waves are released from the barrier through apertures located thereon. The ultrasonic transmitter helps to deter and repel pests from entering a structure of the structure assembly even when the door is open. The barrier serves as a blockade that helps to increase the safety and cleanliness of users as the nuisance of pests such as rodents or snakes is eliminated by the barrier and the ultrasonic waves emitted by the ultrasonic transmitter.
