WebBeta-cyfluthrin (a form of cyfluthrin) has been found to be twice as toxic as cyfluthrin if eaten or breathed in.3 Metabolites of cyfluthrin are less toxic than cyfluthrin itself.11 … Web(bifenthrin, cyfluthrin, lambda cyhalothrin, and tralomethrin) compared to a first generation synthetic pyrethroid (permethrin). The third generation pyrethroids, including bifenthrin, were found to be more toxic to both Ceriodaphnia dubia and Daphnia magna. Reported bifenthrin LC50 for C. dubia was calculated to be 0.07 ppb, LC50 for D. Magna
