The novel insect trap device comprises a body, a first cover body and a drain portion; the first cover body comprises a first perforation; thereby, when the user wants to catch the insect, the fermented fruit and the like are first fermented. The food is placed inside the body, and the first cover is covered. Since the insects like the taste of the fermented food, they are attracted to fly from the first perforation into the body, and because most insects have phototaxis, Continue to fly above the inside of the body until the body is not supported and drop the bottom to catch the insects. In addition, by placing a drain on the body adjacent to the bottom, the liquid produced by the fermented food can be discharged through the drain. Reuse, when fertilized into farmland, it is more environmentally friendly.本新型係捕蟲裝置,其包含一本體、一第一蓋體及一排水部;第一蓋體包含一第一穿孔;藉此當使用者欲捕捉昆蟲時,首先將腐爛的水果等已發酵的食物置入本體內部,再將第一蓋體蓋上,由於昆蟲喜愛發酵食物的味道,因此會被吸引而從第一穿孔飛入本體內部,而因為大多的昆蟲具有趨光性,因此會在本體內部上方持續飛行直到體力不支而掉落底部,達到捕捉昆蟲的目的;此外,藉由在本體上鄰近底部處設置一排水部,因此發酵食物所產生的液體更可以經由排水部排出回收再利用,當成肥料灌溉於農田,更具有環保意義。
