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.
