The invention relates to a structure of a termite exterminating device. A controller is equipped inside the main body which is coupled with a display and a battery device. Further, a plurality of control buttons is disposed on the outside of the main body, and the control buttons are coupled with the controller which joins to a high-voltage transformer. Then, the main body is provided with a microwave unit which comprises a magnetron connected to a waveguide. The waveguide surrounds the outside of the antenna disposed on the magnetron such that the microwave can be concentrated and guided outward for killing termites. Moreover, the microwave can easily pass through insulators in order to exterminate the termites hidden in cabinets, wooden decorations and even under the ground. Accordingly, the danger and damage of termites can be eliminated thoroughly.本發明係有關於一種白蟻撲殺器結構，其主要係於一本體之內部裝設有控制器，控制器耦接有顯示器與電池組，且於本體之外側設置有控制鈕，控制鈕耦接於控制器，再於控制器耦接有高壓變壓器，並於本體設有微波單元，微波單元係包括有磁控管〔magnetron〕，磁控管耦接於高壓變壓器，而磁控管固接有波導管，波導管包圍於磁控管上所設之天線外側，可將微波集中導出而殺死白蟻，且微波係可輕易的穿透絕緣體，以便於確實的撲殺櫥櫃、木質裝潢內甚至於地底之白蟻，可徹底的根治白蟻的危害。
