Product Details

About FourStar®

FourStar microbial larvicide kills mosquito larvae before they become adults by using the naturally occurring bacteria Bacillus sphaericus (Bsph) and Bacillus thuringiensis israelensis (Bti). These active ingredients are inherent in soil and contain protein crystals that when ingested rupture the gut wall of the larvae causing larval death.

To enhance performance, FourStar larvicides contain Central Life Sciences’ patented “Dual Action” release technology. This innovative technology regulates the release of active ingredients to the water surface as well as throughout the water column to ensure a long residual and maximum coverage.

All FourStar formulations are distributed exclusively by Clarke for public health mosquito control use.
