VectoLex^®/Spherimos^® – VectoLex and Spherimos are based on Bacillus sphaericus and control several species of mosquito larvae. These fast-acting products are commonly used in municipal and industrial water treatment facilities, animal waste lagoons, storm sewer catch basins, continuously irrigated croplands and pasture mosquito breeding sites.

VectoLex offers effective residual control of several mosquito species in both clean and polluted waters. While first registered for control of Culex, VectoLex uses have been expanded to include control of several Aedes, Anopheles, Psorophora and Coquillettidia species. Effectiveness against additional species is being researched on an ongoing basis.
