Disclosed is an environmental-friendly mousetrap, which includes a first casing, a second casing and a drawstring bag. The drawstring bag is placed inside the first casing, and then the first and second casings are integrally connected. A single-way gate piece is configured in an opening of the second casing. A draw string configured on an opening of the drawstring bag has two ends that are extended to the exteriors of the first and second casings. Once a mouse enters the drawstring bag, the mouse cannot escape therefrom owing to the hindrance of the single-way gate piece. A user can externally pull the draw string tightly to seal the opening of the drawstring bag so that the mouse can be packed in the drawstring bag, and then the first casing and the second casing are separated and the drawstring bag enclosed with the mouse can be removed for cleaning. Accordingly, the users fear can be greatly reduced without manually touching and seeing the trapped mouse during the cleaning process.一種環保捕鼠器(一),包括一第一殼體、一第二殼體及一束口袋。其中該束口袋係放置於該第一殼體內部後,再將該第一殼體與該第二殼體結合成一體,且於該第二殼體之開口內部設有一單向閘片,並且,該束口袋之袋口設有一束繩,其二端係延伸至該第一殼體及該第二殼體的外部。當老鼠進入該束口袋之後,由於受到該單向閘片的阻礙而無法脫出,使用者可由外部操作拉緊該束繩以封閉袋口,使老鼠被包裝於該束口袋內,再將該第一殼體及該第二殼體分離並取出裝有老鼠之該束口袋進行清理,能以不沾手的方式進行清理工作,且過程中也不會看見老鼠而降低恐懼感。1‧‧‧環保捕鼠器(一)11‧‧‧第一殼體111‧‧‧第一開口1111‧‧‧第一結合部1112‧‧‧穿繩口112‧‧‧視窗12‧‧‧第二殼體121‧‧‧第二開口1211‧‧‧第二結合部122‧‧‧第三開口123‧‧‧單向閘片124‧‧‧投藥口13‧‧‧束口袋131‧‧‧束繩132‧‧‧黏貼部
