An insect-proofing device comprises a shell body, at least one net body, and at least one fixation means. The shell body comprises a plurality of mutually-pivoted shell plates that are capable of being selectively opened in an unfolded state or being closed in a covered state, and each surface of the shell plate is configured with at least one first opening. The net body containing volatile insect-proofing drugs is utilized to cover on the first opening of the shell plate of the shell body. The fixation means is utilized to fixedly arrange the net body on one side of the first opening of the shell plate of the shell body. In the operation of the insect-proofing device, the shell plates of the shell body can be opened in the unfolded state to greatly increase the contact area with air for the net body, thereby promoting the usage efficiency of the insect-proofing drugs and attaining usability and inventiveness of facilitating replacement operation.一種防蟲裝置,包含:一殼體,具有複數個相互樞設的殼板,使複數個殼板之間可選擇性地開啟呈現出一展開狀態,或閉合呈現出一蓋合狀態,且每一個殼板表面分別設有至少一第一開口;至少一網體,含有揮發性的防蟲藥劑,並且覆蓋於上述第一開口;以及至少一固定手段,將上述網體裝設固定於上述殼板的第一開口一側;藉此,所述防蟲裝置使用時,其殼板可開啟呈現出一展開狀態,以大幅增加網體與空氣的接觸面積而能夠達到提昇防蟲藥劑之使用效率且利於進行更換作業之實用進步性。B‧‧‧防蟲裝置10‧‧‧殼體11‧‧‧殼板20‧‧‧網體30‧‧‧固定手段31‧‧‧連接件32‧‧‧夾件33‧‧‧組接孔34‧‧‧第二開口40‧‧‧定位手段41‧‧‧凸柱42‧‧‧套管
