The invention discloses a
cockroach catching and killing device and relates to the technical field of animal catching. The
cockroach catching and killing device comprises a box, a first rotary door and a second rotary door. The first rotary door and the second rotary door are arranged at the top of the box. A first support part, a second support part, a third support part, a first
electromagnet, a first controller, a second controller and a second
electromagnet are arranged in the box at intervals. The first support part, the third support part and the box form a catching chamber together in a surrounding mode. The first
electromagnet and the second electromagnet are arranged outside the catching chamber and are connected with the first controller and the second controller correspondingly. According to the
cockroach catching and killing device, a cockroach is attracted by a homemade bait at the top end of the cockroach catching and killing device, an
inductor induces the position of the cockroach, and thus the rotary
doors are controlled to be opened or closed through the electromagnets. The second support part is further provided with a
power grid plate, so that the cockroach falling into the cockroach catching and killing device is stunned or killed through striking. A glue layer is arranged on the bottom layer of the cockroach catching and killing device to prevent the cockroach from escaping, and cockroaches can be continuously and effectively caught and killed.
