An infrared ray detection and ultrasonic wave oscillation animal chaser includes a front case, a shell, a water-resistant cover, an infrared ray detection circuit board and an ultrasonic wave oscillation circuit board. The front case, shell and the cover have latching hook and grooves, and engaging rails and slots to enable them to be assembled or disassembled easily and quickly. The infrared ray detection circuit board and the ultrasonic wave oscillation circuit board are housed in the front case and the shell, and can sense and detect the infrared ray emitted from animals, and then emits high frequency ultrasonic wave to expel intruding animals away. The ultrasonic expelling device is powered by a battery set and therefore can be conveniently hung on an outdoor wall or incorperated with an adjustable strut at a suitable height enable to be located on the ground near the protected area.
