The brown-banded cockroach, Supella longipalpa (Fabricius), and the German cockroach, Blattella germanica (L.), are two of the most important indoor pest cockroach species. Management of these two pest species is heavily reliant on chemical control. While commercial gel bait formulations have been evaluated extensively against the German cockroach, information on the performance of toxic baits against the brown-banded cockroach is limited. Here, we compare the efficacy of several bait formulations against each species of cockroach in small test arenas and Ebeling choice boxes. Our results indicate that the effectiveness of gel baits differs between the two pest species. The implication of the findings on the management of the brown-banded cockroach is discussed.
