Mosquitoes are dangerous transmitters of disease. Each year, about 300 million people are infected with diseases such as Malaria and Zika and nearly one million people die. Other deadly mosquito-vectored diseases are West Nile fever and Dengue.
Microbial mosquito larvicides have gained considerable acceptance in recent years.

Sefralit® is a formulation of Bacillus sphaericus (Bs) for control
of mosquito larvae. This unique strain of Bs offers advantages in comparison to chemical insecticides and is relatively safe for humans and non-target organisms.

It is particularly effective in controlling mosquito larvae in waters high in organic matter such as catch basins, animal waste lagoons, and stagnant ponds.

SEFRALIT® AS is an aqueous suspension formulation (also known as SC-Suspension Concentrate) that sprays easily through many equipment types. Liquid sprays have been demonstrated to work extremely well to treat Culex spp. in “closed” habitats.

SEFRALIT® WDG is a water dispersible granule formulation, easily transported and dispersed in water.
