A trap device with a reminder function is suitable for engaging a container and trapping a plurality of insects, the trap device comprising a housing unit, a pivot unit, and a mobile unit. The pivoting unit includes a pivot shaft that is transversely disposed through the outer casing unit, and a warning member coupled to one end of the pivot shaft. The moving unit is vertically and diametrically disposed in the outer casing unit, and the upper end and the lower end are respectively connected to the pivoting unit and the container. When the container is filled by the insects, the moving unit is moved downward by gravity traction. And moving from a no-load position to a full-load position relative to the outer casing unit, and driving the warning member to rotate. In the idle position, the moving unit is relatively adjacent to the top surface of the outer casing unit, and the warning member is substantially horizontal, and in the fully loaded position, the moving unit is relatively far from the top surface of the outer casing unit, and the warning is The piece is oriented upwardly to remind the user to replace the container.一種具提醒功能的誘蟲裝置，適用於銜接一容器並誘捕數隻昆蟲，該誘蟲裝置包含一外殼單元、一樞轉單元，及一移動單元。該樞轉單元包括一橫向穿設於該外殼單元的樞軸，及一連接於該樞軸的一端的警示件。該移動單元是可上下穿伸地設置於該外殼單元中，且上端及下端分別連接該樞轉單元及該容器，該容器被該等昆蟲填滿時，該移動單元會受到重力牽引向下移動且相對於該外殼單元由一空載位置移動至一滿載位置，並帶動該警示件轉動。在該空載位置時，該移動單元相對鄰近該外殼單元的頂面，且該警示件實質上呈水平，而在該滿載位置時，該移動單元相對遠離該外殼單元的頂面，且該警示件實質上朝向上方，以提醒使用者更換該容器。
