摘要： The present invention relates to an insect trap for attracting insects using a UV LED and sucking and capturing the attracted insects with a fan. The insect trap of the present invention comprises: a body; a suction part provided on one side of the body; a fan installed behind the suction part; at least one UV LED, provided on the body at least around the fan, for irradiating ultraviolet rays forward; a discharge part for discharging air sucked in by the suction part in a direction different from the air suction direction of the suction part; a duct which is an air passage from the suction part to the discharge part; a first streamlined inner surface, provided on an inner wall side opposite to a direction in which the duct extends on the basis of the suction part, for guiding air sucked into the suction part toward the duct; and an insect net, installed in the discharge part, for passing the air therethrough and capturing insects being sucked in together with the air.
