Abstract: Electromechanical apparatus producing random ultrasonic noise is disclosed for killing insects. A number of coils are provided, each having primary and secondary windings which are wrapped around a metal core. The windings are electrically interconnected to each other and to a power source. The current through the windings is controlled by a number of digital signals having random pulses and random intervals between pulses. The random pulses rapidly turn the current through the windings on and off. This causes the metal cores to vibrate extremely randomly thereby producing random noise.

Abstract: Ultrasonic pest control apparatus comprising a pair of transducers, one in the form of a ring and the other in the form of a disc positioned within the ring, carried by a housing, a pair of oscillators operatively connected to the transducers, a timer controlling the oscillators, and a reflector extending from the housing. The oscillators apply to the transducers electrical signals having frequencies different from the natural frequencies of the transducers, and the timer controls the oscillator duty cycle.

A system includes a pair of units in opposed alignment whereby sound waves of one unit work against sound waves of the other. A gas-tight sealing arrangement associated with transducer and housing permits safe operation in explosive atmospheres.

Abstract: Rodents are attracted to a pre-selected location by generating ultrasonic signals having pre-determined frequencies, time durations and repetition rates which correspond to instinctual vocalization of rodents. A recording is made of the sounds generated by young rodents which recording is digitized and stored in a memory unit. The stored recording is non-destructively read out of memory and converted back to an analogue signal which substantially corresponds to the sound wave form generated by the young rodent. This signal is amplified and converted to a sound signal in an appropriate transducer for attracting rodents to a pre-determined location.

Abstract: A generator vibrates low frequency sound vibrations and magnetic fields with superimposed high frequency noise which upsets the habits of rodents and most burrowing animals. The sounds are transmitted to the ground by the generator being connected to a pipe or shaft embedded in the ground, to buildings, structures or to water pipes which run underground. The circuitry permits random frequencies to be generated at random intervals by the use of cycling thermostats in circuit with the sound generator. The thermostats cycle due to the heat of the coils or resistors or from an electronic randomizing control circuit.

Abstract: A soil or other ground cover is treated for termite or other pest control by dispersing in the soil or on the ground, a toxic insecticide in an active available state and a toxic insecticide in an initially unavailable state and timed to be released before complete dissipation of the immediately available insecticide. The initially unavailable insecticide is enveloped in a container made of a material either in whole, in part attractive to and edible by the pest to release the insecticide when the container or plug is eaten by the pest. Combined with the insecticide is any odoriferous material which will signal the presence of termites by its distinctive odor. A soil coloring agent can be used also or in addition to provide a visual signal. The odor producing agent can be used alone.
