Adult cat fleas, Ctenocephalides felis felis (Bouché), on cats (Felis catus) were exposed to emissions from an ultrasonic flea collar worn by the cat. No significant differences were found in total numbers of eggs produced per day (mean = 524 control, 614 treatment), in length of larval development time (mean = 7.7 d control, 7.7 d treatment), or in total daily pupal production (mean = 485 control, 445 treatment) between the treatment and the control groups. Tests off the host were conducted to determine whether ultrasonic exposure caused mortality in adult fleas; no significant differences were found in daily mortality between the treated and control fleas during 1 wk of exposure.
