Abstract:

Four models of commercially available ultrasonic pest control devices were characterized acoustically with sound level meters, sound spectrum analyzers, and an oscilloscope in connection with a signal averaging computer. Results indicated that the devices fell short of the manufacturer claims in both intensity of output and frequency regions of maximum energy. A single thickness (0.30 cm) of cardboard attenuated the output by ca. 70 dB. In these tests, ultrasound neither controlled nor repelled test insects nor increased their susceptibility to chlorpyrifos.
