This thesis presents design and build devices that used to chase squirrels in the Park, durian, to help minimize the damage from that squirrel came into biting the productivity of farmers. We therefore devised a machine with squirrel chasing, ultra sonic frequency (Ultrasonic Generator Sweepable) on ultra sonic frequency. In the frequency range of 20 kHz-60 kHz by the circuit consists of the circuit determines the frequency (Frequency Scanner) frequency generator (Frequency Generator) and a push-cycle pool suppliers file mopri (Push-Pull Amplifier) is defined as the frequency value causes the frequency to a frequency generator and sent to drive the ultra Ultrasonic sensors has been Sou khotran sadio electric pianos for streamlined use broadcasting spectrum ultra sonic.
