To provide a device for efficiently exterminating terrestrial firefly larvae, an invasive species, while minimizing the impact on non-target organisms. [Solution] This device comprises an attractant section, which attaches the mucus of terrestrial snails to absorbent and adsorbent kite string to form a simulated mucus trail (3), and a cylindrical guide and pesticide treatment section, through which the kite string passes and whose interior is coated with mucus and insecticide, simulating the shell of a terrestrial snail. Terrestrial firefly larvae (4) are attracted by the mucus and enter the cylindrical guide section (1), where they are selectively killed by contact with the insecticide (2) coated on its inner wall. Furthermore, by connecting multiple guide sections or forming them into a ring and placing a shellfish bait in the center, the formation of a mucus trail is promoted as the snails are attracted to the device, thereby increasing the efficiency of luring the larvae. Additionally, by adjusting the diameter and length of the tube and the density of the devices, it is possible to selectively exterminate larvae of specific body sizes and mobility. For pesticide treatment, an aerosol formulation for indoor pest control is sprayed onto the inner wall of the tube.
