PROBLEM TO BE SOLVED: To provide a noxious insect capturing tool capable of easily capturing a noxious insect such as stink bug at any position in a room such as on a window sash.SOLUTION: The noxious insect capturing tool 1 is provided with a capturing tool body 2 and an inner plug 5. The capturing tool body has a nearly funnel shape provided with a leg part 21, a slip down part 23 positioned above the leg part 21, and a capture part 25 positioned above the slip down part 23 and constructed of a plurality of flat plates. The capture part 25 is constructed of eight flat plates which have equal height and are perpendicularly bonded at side edges to form a frame having a nearly T-form by top view. A specific one plate of the flat plates forms a first capture plane 41, and flat plates connected to both sides of the first capture plane 41 form a second capture plane 42 and a third capture plane 43, which have widths narrower than the first capture plane 41. The width of the second capture plane 42 and the third capture plane 43 is 11-18 mm.【課題】 カメムシなどの害虫が窓のサッシなど室内のどのような位置にいても容易に捕獲が可能な害虫捕獲具を提供する。【解決手段】 捕獲具本体２と中栓５を備えた害虫捕獲具１であって、捕獲具本体は、足部２１と、足部２１の上方に位置する滑落部２３と、滑落部２３の上方に位置し複数の平面板で構成される捕獲部２５と、を備えた略漏斗形状であり、捕獲部２５は、高さが等しい８枚の平面板が側端辺で垂直に結合されて上面視略Ｔ字状の枠体であり、前記平面板の所定の一枚が第一捕獲面４１とされ、第一捕獲面４１の両側に接続された平面板が第一捕獲面４１よりも幅が狭い第二捕獲面４２及び第三捕獲面４３とされ、第二捕獲面４２及び第三捕獲面４３の幅が１１ｍｍ乃至１８ｍｍとされる。【選択図】 図１
