    Product Description

    Fenvalerate is a pyrethroid ester insecticide and acaricide.1,2 It is a slow activator of voltage-gated sodium channel 1.8 (Nav1.8).1 It induces mortality in pyrethroid-susceptible and -resistant strains of M. domestica (LD50s = 0.014-5 µg/fly).3 Fenvalerate also induces mortality in tobacco budworm larvae but is associated with pyrethroid resistance with an increase in LD50 values from 1.01 to 20.85 µg/g over a six-year timeframe.4 It induces mortality in 95.5% of T. macfarlanei spider mites when applied to leaves at a concentration of 0.015%.2

    WARNING This product is not for human or veterinary use.
