More information about DUET™:

DUET™ is a dual-action adulticide designed to maximize control of nuisance and disease-carrying mosquitoes. DUET combines two actives: sumithrin, the active ingredient in Anvil™, and prallethrin, known for its superior knockdown. These two actives work in concert to provide excellent control under a variety of operating conditions. Anvil™ is a mosquito spray product by the same company that the Health Department has used successfully for several years. Initial field trial and cage trial observations have shown that DUET causes “benign agitation” – a non-biting excitation of mosquitoes. Benign agitation has the potential to draw mosquitoes from a resting state – possibly including mosquitoes never before factored into efficacy calculations -- into on-the-wing activity. When mosquitoes are flying rather than resting, more of the spray comes in contact to kill them. DUET has the same environmental profile as Anvil, which is widely regarded as having minimal environmental impact. No special steps need to be taken by residents in areas where DUET is applied, and you can go outside immediately after DUET has been sprayed. Very little DUET is required for superior control -- one to just over three tablespoons of formulated product treats an area the size of a football field. A distinct advantage for late-season applications, DUET also demonstrates an ability to maintain its efficacy even in colder weather. This gives improved coverage for early- and late-season applications – prime time for combating West Nile Virus. DUET can be applied via ground or air, and can be applied neat or diluted. DUET is registered by the EPA for public health outdoor mosquito control, and is widely registered in states throughout the U.S.
