Four types of exterior perimeter treatments for the control of Pharaoh ants, Monomorium pharaonis (L.), in houses were compared. Treatment with a granular bait containing hydramethylnon, a delayed-action toxicant, resulted in a 95% reduction in foraging activity 1 and 4 weeks after treatment. Houses treated with either an insecticidal residual spray, insecticide granules, or a granular bait containing a contact insecticide, had an average increase of 22% in foraging activity. Foraging by Pharaoh ants on a delayed-action toxicant bait applied solely to the exterior periphery of houses controlled Pharaoh ant colonies located inside the structure. Exterior perimeter baiting for Pharaoh ants could reduce indoor insecticide applications. /// Fueron comparados cuatro tipos de tratamientos de perímetro exterior para el control de la hormiga faraón, Monomorium pharaonis (L.) dentro de casas. Un cebo granular conteniendo hydramethylnon, un tóxico de acción retardada, produjo un 95% de reducción de la actividad forrajera una y cuatro semanas después del tratamiento. Las casas tratadas con aspersiones de un insecticida resisdual, gránulos de insecticida o un cebo granular conteniendo un insecticida de contacto tuvieron un incremento promedio del 22% en la actividad forrajera. El forrajeo de las hormigas faraón sobre un tóxico de acción retartdada aplicado solamente a la periferia de las casas controló las colonias localizadas dentro de la estructura. El uso de cebos exteriores para las hormigas faraón podría reducir las aplicaciones de insecticidas al interior de las casas.
