Two aqueous 0.25% AI wettable powder suspensions of permethrin and cypermethrin were evaluated in German cockroach, Blattella qermanica (L.), infested residences. German cockroach population size was assessed in each residence prior to insecticide application and once monthly for 6 months following the single insecticide application. Assessment consisted of placing an unbaited Mr. Sticky sticky trap within each residence for one night at the following locations: under kitchen sink, adjacent to stove or refrigerator, behind toilet in each bathroom, and adjacent to furnace in homes with a basement. Cockroaches caught in traps were counted and cockroaches caught/trap/night calculated. Insecticides were applied using a banding technique with the 3.8 L B&G hand operated compressed air sprayer operated at 137.9 kPa pressure and fitted with a fan spray nozzle. Records were kept of the amount of insecticide sprayed and time required to treat each residence.
