In Benin, cockroaches are infesting urban environments and developing resistance to commonly used insecticides. Therefore, alternative insecticides is important for management. The present study aims test the efficacy of a gel bait formulation-2.15% imidacloprid against common cockroach Periplaneta americana under laboratory field conditions in commune Abomey-Calavi. Dead alive were compared before after exposure 2.15% imidacloprid. as well community, mortality rates more than 50% 24 hours consumption bait. Under conditions, rate was 100% eleven (11) days while an overall 86.97% [84.3-89.3] observed restrooms 84% [76.3-89.9] kitchens 8 weeks treatment with similar latrines kitchens. Overall, among adult 94.85% [92.8-96.5]) versus 65% [58.6-71.0] nymphal cockroaches. did not prevent egg hatch from ootheca.
