PURPOSE: A chemical spray control device of a pest controller is provided to perform a pest control work without operating an engine capable of immediate reaction compared to a multistage spur gear and to cover high pressure. CONSTITUTION: A chemical spray control device of a pest controller includes a ball valve driving motor(20) generating a rotational force in the forward and reverse direction according to the polarity of the supplied power, a decelerator(30) transferring a rotational force of the ball valve driving motor; a ball valve(40) opening and closing the distribution line while being rotated in the forward and the reverse direction by the rotational force transferred to the decelerator; and a controller(50) changing the polarity of power and controlling operation and direction of rotation of the ball valve driving motor while supplying power to the ball valve driving motor.
