DURAFLEX ZC is a cost-effective, low-odor treatment for control over mosquitoes, ticks, spotted lanternflies and other labeled pests — both now and later. The ZC formulation is a mixed formulation containing one or more active ingredients of a CS (capsule suspension) and SC (suspension concentrate). DURAFLEX ZC concentrate combines bifenthrin with novaluron and pyriproxyfen. The result is an all-in-one product that contains one adulticide and two insect growth regulators (IGRs). This not only breaks the life cycle of insect reproduction for its labeled pests; it also extends the longevity of bifenthrin.
