<p>Electroshock type insect-proof device consisting of a chamber (2) having an opening (3), at least a pair of electrodes (5a), (5b), to which a voltage is applied, arranged in parallel with each other via an insulating gap (W) on a wall surface (1a) around the opening (3), and a stopper member provided between the chamber (2) and electrode (5b) so as to project beyond the surface of the electrode (5b). This device is adapted to give an electroshock to a cockroach entering the chamber (2), and thereby reliably prevent the entry of the cockroach into the chamber (2).</p> |
