The only sure way to eliminate ants and roaches is to target them at their source with Combat® baits and gels. Combat is a highly effective ant and roach insecticide disguised as a food source. To roaches, Combat's carbohydraterich formulation is a delicious mixture that is irresistible. Once ingested, roaches return to their nests, die, and are eaten by other roaches further spreading the insecticide to the rest of the nest.
