PROBLEM TO BE SOLVED: To provide a mosquito inducing and trapping device capable of trapping more mosquitoes.SOLUTION: A mosquito inducing and trapping device (10；10A) includes: a case (50)； an ultraviolet irradiation part (80) capable of applying ultraviolet light to a photocatalyst (111) accommodated in the case (50)； a suction part (70) for sucking ambient air from one end (50d) of the case (50)； a collection part (40) that faces the other end (50c) of the case (50) capable of collecting mosquitoes (M) sucked by the suction part (70) together with ambient air； and an opening (50b) formed at a side face part (50a) of the case (50) where the ambient air sucked by the suction part (70) is discharged to the outside of the case (50). The opening (50b) is fitted with a grid-like louver (120；120A) that extends to the inside of the case (50).
