Minneapolis, January 29, 2021 — MGK introduces Sumilarv® 0.5G and Sumilarv® WSP, two mosquito larvicides that deliver a distinct mode of action and set a higher industry standard for effectiveness. This new product marks a significant advance, with the promise of a longer-lasting and a highly efficient new tool to better control mosquitos.

“Sumilarv 0.5G and the simple to use Sumilarv WSP sachets represent an exciting advance in the effort to control mosquitos,” says Dr. Jennifer Williams, an MGK entomologist and recognized expert in vector control.

Dr. Williams presented data showing that a single application of Sumilarv 0.5G or Sumilarv WSP can provide effective residual control.

“Pyriproxyfen, the active ingredient in Sumilarv, is up to 50 times more effective than methoprene and up to 500 times more effective than spinosad,” notes Dr. Williams. “This distinct mode of action and low-dose toxicity make Sumilarv 0.5G an ideal addition to a rotational strategy for resistance mitigation.”

The dense, granular, sand-like formulation is easy to apply and sinks in water, where it naturally binds to organic matter and concrete — resisting flushing and dilution.

Extensive field studies have demonstrated that Sumilarv 0.5G delivers reliable larval control after just a single dose. “This unmatched duration of activity enables mosquito abatement organizations to greatly reduce the frequency and costs of re-application,” says Dr. Williams.

Mosquito control organizations across the U.S. have tested Sumilarv 0.5G in applications like stormwater catch basins, water retention ponds, livestock lagoons and other common mosquito breeding sites. In each application, Sumilarv’s long-lasting efficacy was confirmed.

Dr. Stephen Manweiler, executive director of the Metropolitan Mosquito Control District of Minneapolis, Minnesota notes that, “tests of Sumilarv 0.5G provided effective season-long control (June- September) of larval mosquitoes including Culex in catch basins with just one treatment.”

Sumilarv 0.5G and Sumilarv WSP join proven MGK botanical adulticides and barrier sprays that enable more targeted treatments and provide a comprehensive portfolio of mosquito control products.
