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.
Poison Bait. Poison baits work better than spray insecticides. Roaches eat the bait, which will kill them, but not right away, and go back to their homes. As these roaches defecate, other roaches eat their feces and get poisoned. When these poison bates were developed, it marked a major turning point in our battle against roaches. Traps. Traps can be used to help reduce a cockroach population, and, especially to gauge how bad your infestation is.
