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.
Spray any visible insects in the home with the mixture.
