NOVELTY - Insect-repellant/trapping device comprises fixed frame (1), opponent handle (2), hemp rope (3) and net body (4). The fixing frame includes upper frame (5), lower frame (6) and bracket (7). The upper frame is square opening with two opening edge for connecting with two end of hemp rope. The lower frame is round frame structure. The net body is double-layered net body, where lower layer is nylon network body with 35-40 meshes, and upper layer is cotton yarn. The cotton yarn net body is coated with insect repellent composition.    USE - As a device for repelling or trapping insect (claimed).    ADVANTAGE - The present insect-trapping device is simple, cost-effective, and convenient; utilizes net which is convenient to disassemble; is simple to maintain, and can be reused; utilizes bracket provided with insect storage liquid and through hole which enhances the insect repellent effect; and is environment-friendly.    DETAILED DESCRIPTION - Insect-repellant/trapping device comprises fixed frame (1), opponent handle (2), hemp rope (3) and net body (4). The fixing frame includes upper frame (5), lower frame (6) and a bracket (7). The upper frame is a square opening with two opening edge for connecting with two end of hemp rope. The lower frame is a round frame structure. The four brackets are fixed in the frame at four intermediate vertices and bottom border. The net body comprises a network body and four lower network body. The net body fixed on a square area in lower bracket and a form of inner frame, and the other net body fixed on the hemp rope. A circular area and the lower area in the bracket are surrounded by inner frame. The net is fixed below the border surrounded by circular area. The bracket has cylindrical structure; and is provided with uniform 3-6 liquid storage cavity wall sets. The liquid storage cavity wall set is provided with through holes having a diameter of 3-15 mm. The opponent handles are relatively fixed on upper frame of two vertices. The net body is double-layered net body, where the lower layer is a nylon network body with 35-40 meshes, and the upper layer is cotton yarn. The cotton yarn net body is coated with insect repellent composition. An INDEPENDENT CLAIM is included for the preparation of insect repellent/trapping device, involving crushing the ingredients of plant and mixing in an aqueous solution of 70% ethanol 6-8 times at 55-65 degrees C for 2-4 hours, filtrating to obtain plant extracting liquid; mixing the plant extracting liquid in a tank, stirring at normal temperature for 25-35 minutes at a speed of 800-1200 revolutions per minute to obtain mosquito repelling medicine liquid; soaking the cotton net body into insect repellent liquid at 60-75 degrees C for 48-72 hours and drying; and assembling the device by using combining the cotton net body with nylon net body.
