From an experiment by using audio frequencies transmitted into boxes with cockroaches using frequency detectors found that cockroaches have a frequency response behavior. 49.2-57.2 KHz without range that cockroaches have been responding to the frequency in the KHz range 51 to 52.5 KHz by the observed symptom is spasm or arm; Remove legs, rubbing his back and walked non-stop motion.

Experiments by using radio frequencies sent into the box by using a detector with cockroaches cockroaches found that the frequency response behavior by 49.2-57.2 KHz frequency range frequency response with cockroaches during 51. KHz to 52.5 KHz symptom is observed to have a spasm shook her leg to rub mustache and went non-stop movement.

From the experiment by using frequency sound sent into the box with the ตรวจจับความถี่ found cockroaches cockroach behavior response spectrum 49.2-572 KHz by the cockroaches have frequency response in the 51 KHz to 52.5 KHz by symptoms that notice is a spasm flick Leg rubbing tentacles around and walked non-stop Mobile
