Poison baits consisting of some food material with a toxicant such as phosphorus or boric acid have been used for many years for controlling the cockroaches (Mallis 1954, pp. 181-5). Recently Keller et al. (1956) reported that a bait consisting of cornmeal (73 percent), Coca-Cola syrup (25 percent), and Dipterex (2 percent) controlled Periplaneta spp. in homes for 30-60 days.
