The invention relates to a mousetrap device, which mainly comprises a holding body, a sensing unit in the holding body, and a uniform actuator above the holding body. The actuator and the sensing unit are respectively connected to a control unit. Therefore, the sensing unit is used to detect whether there are rodents in the sensing holding body, so as to be driven by the control unit. The actuator acts to close the cover opposite to the holding body, so as to effectively catch mice.本創作係有關於一種捕鼠裝置，其主要包含有一容置本體，該容置本體內設有一感測單元，且於容置本體上方設有一致動器，該致動器與感測單元分別連接於一控制單元；藉此，利用該感測單元對應偵測感應容置本體內是否有鼠類動物進入，以能經由控制單元驅使致動器作動，而關閉與容置本體相對的蓋體，達到有效捕抓老鼠的功效與目的者。
