The
American cockroach is the largest--up to 2 inches--pest species
found in most states. It is mahogany-colored with a yellow margin
around the head and around the shield behind the head. Although
occasionally found in basements and attics of homes, the American
cockroach more commonly is found in warm, moist areas of
industrial or commercial buildings. Furnace or boiler rooms,
sewers and heat tunnels are favored environments.
Cockroach baits
contain a slow-acting insecticide incorporated into a food
attractant. Roaches locate and feed on the bait, typically contained
in small, plastic bait trays, gels, granules and then they crawl
away to die. Bait carried back to the nesting area also kills other
roaches after being expelled in the sputum and feces.
In contrast to liquid sprays or aerosols, cockroach baits require no
mixing and it is not necessary to empty kitchen cabinets or cover
food preparation surfaces prior to treatment.. Another advantage of
cockroach baits is that they have essentially no volatility or odor
