Abstract: A cockroach extermination apparatus is disclosed having an outer enclosure with an open top end and a plurality of entranceways at a bottom end thereof. An inner cylindrical enclosure is receivable in telescoping fashion within the outer enclosure. The inner enclosure has a top wall and creates a darkened environment. The inner enclosure is adjustable so as to selectively close the entranceways. Within the inner enclosure a beehive-like core is removably secured in screw-like fashion. The core has a plurality of inner entranceways and a plurality of pockets into which cockroaches crawl in the darkened environment. When desired, the cockroaches are exterminated by closing the outer entranceways and then, when desired, removing the inner enclosure, unscrewing the core, and holding the core under a stream of water to wash away the cockroaches.
