In recent years, measures against wildlife damage have become an urgent issue in farming and mountain areas. However, hunting is prohibited for unlicensed people under the Wildlife Protection and Management Act, and the available measures are limited. The available measures also have problems such as effectiveness and cost, making them difficult to fully adopt. There is an urgent need for effective, safe, and economical measures against wildlife damage that can be implemented by ordinary people without being subject to the above regulations. [Solution] Traps, including snare traps, are subject to the above-mentioned law because they are used to capture harmful animals. The present invention proposes a solution to this problem by attaching a shackle, such as a sound device, to the harmful animal without capturing it, and then allowing it to escape. The present invention uses the force of the harmful animal trying to escape to release the connecting means immediately after the shackle is attached, and by using a trigger means with increased sensitivity, the device can be used not only for relatively large harmful animals such as wild boars, but also for small harmful animals such as masked palm civets.
