Tasting hairs on the legs of a roach can not only help it determine a food source, but help it avoid pesticides as well. Glycocides -- poison baits mixed with glucose -- were traditionally used to dose the sweet-loving cockroach with lethal toxins.
Roach bait is a modern pest control used for the extermination of cockroaches at indoor locations. The effectiveness of this method of pest control exploits the cannibalistic, coprophagic, and emetophagic tendencies of cockroaches.ait placed in the open, away from a wall, is essentially non-effective because cockroaches are less likely to locate it. Twice as much food per day was consumed when it was next to a nest rather than 50 cm away.
