Abstract
Abstract A device for capturing cockroaches which has an attracting body having a food retainer and a plurality of passages connecting the food retainer to the exterior. A lower shield plate open-able only from the exterior is disposed in each passage, and a capturing body having removable upper shield plates rests on the attracting body and has communication ports opposite to the lower shield plates at the bottom thereof. The upper shield plates are openable only from the attracting body side at the communication ports. The lower shield plates are rotatably supported on the upper portion of the passages by bearing shafts and are inclined toward the food retainer side. Each lower shield plate has a ventilating portion of sawtooth shape at its lower end and preferably a balance weight on the upper end thereof on the other side of the bearing shaft from the ventilating portion.
