Go Microbial on Mosquitoes with FourStar® Larvicides
When it comes to mosquito control, smart strategies start at the source. FourStar® microbial larvicides target mosquito larvae before they ever become a problem, using naturally occurring bacteria to deliver powerful, long-lasting results.
Naturally Effective, Environmentally Friendly
FourStar® harnesses the power of two soil-borne bacteria, Bacillus sphaericus (Bsph) and Bacillus thuringiensis israelensis (Bti). Once ingested by mosquito larvae, these bacteria release protein crystals that rupture the larvae’s gut wall, stopping development in its tracks. It delivers targeted, efficient control with a positive environmental profile, making it a great fit for applications requiring sustainable pest management.
Built to Perform, Designed to Last
What sets FourStar® products apart is our patented Dual Action release technology. This innovative feature delivers active ingredients both at the water’s surface and throughout the water column, ensuring consistent coverage and an extended residual. The result? Fewer applications, effective results, and peace of mind knowing the job is done right.
FourStar larvicides offer an effective option for mosquito control professionals looking to rotate the active ingredients used in their larviciding programs. This rotation helps manage resistance and maintain the effectiveness of mosquito control efforts.
Flexible Formulations for Any Application
Whether you’re working on the ground or making aerial applications via drones, FourStar® products are available in a range of formulations to suit your needs. It’s the first microbial product line to combine Bti and Bsph in multiple formats, giving you more control over how and where you apply.
Products like FourStar® Bti CRG are ideal for drone applications, with high bulk density, uniform granule sizes, and broad, consistent swath widths. That means better flow, better coverage, and better results—no matter the terrain.
