The utility model relates to a flycatcher structure, which comprises: an outer cylinder body having a circular or polygonal outer cylinder body； the outer cylinder body is an outer cylinder body with a large upper and a small reverse cone shape, and an inner passage tube is arranged inside the outer cylinder body. The inner channel tube is a circular or polygonal inner channel tube, and the inner channel tube is an inner channel tube with a small upper and a large cone shape, and the bottom of the inner channel tube is sealed or integrally formed to the inner wall of the outer cylinder, so that the inner channel tube and the outer tube tube are externally An accommodating space is formed between the cylinders to accommodate an appropriate amount of aqueous solution, and a plurality of legs are arranged at the bottom of the outer cylinder to form a slotted hole therein. The slotted hole is a bait placement area, and the top surface of the outer cylinder body is provided with an upper cover. Sealing the top surface, thus forming a flycatcher； the flycatcher has a simple structure, no plug-in, no assembly, no maintenance, no structural damage, and is environmentally friendly and long-term use.一種捕蠅器結構，係包括：一外筒體為圓形或多邊形的外筒體，外筒體為一上大下小反錐狀的外筒體，外筒體內部設有一內通道管，內通道管為圓形或多邊形的內通道管，內通道管為一上小下大錐狀的內通道管，內通道管底部往外筒體內壁密封連接或一體成型，使其內通道管與外筒體間形成一容置空間而可容放適量的水溶液，外筒體底部設數支腳使其間形成開槽孔，開槽孔內為誘餌放置區，外筒體頂面蓋設有一上蓋得以密封頂面，如此得以形成一捕蠅器；該捕蠅器結構構造簡單，免插電、免組裝、免維修，沒有機構損壞的問題，深具環保及長時間使用效益者。
