Efficacy of 10 commercially available household permethrin products against Culex quinquefasciatus.
Ten commercial household permethrin products in aerosol formulations were evaluated for knockdown (KD) and mortality of female Culex quinquefasciatus. The permethrin concentrations of these products ranged from 0.05% to 0.50%. Eight of the 10 products produced significant KD (%) and mortality (%) posttreatment. At 15 min posttreatment, 3 household permethrin products provided 100% mortality. At 60 min posttreatment, 8 products provided 100% mortality. At 120 min, only 2 products resulted in less than 100% mortality with permethrin concentrations of 0.05% and 0.10%. A linear regression analysis shows a significant relationship between the mortality and times posttreatment.
