Spheratax SPH 50G Granules provide powerful selective mosquito control when placed where mosquitoes breed. This microbial larvicide contains Bacillus sphaericus spores, a naturally occurring beneficial organism. When used as directed and introduced to organic-rich water sites, spores are consumed by mosquito larvae. Once ingested, the bacteria spores release toxins into the guts of juvenile mosquitoes. These toxins bind to receptor cells in the digestive system, causing larvae to stop eating and die. This process only affects actively feeding mosquito larvae and does not affect other adult insects, birds or mammals.
Consider using Spheratax SPH 50G WSP or Aquabac Xt if granular applications are not suitable in your treatment area. Both are similar mosquito larvicides with minimal impact on non-target pests.

Wastewater, Storm Water/Drainage Systems, Marine/Coastal Areas, Water Bodies, Dormant Rice Fields - 5-20 lbs per acre of water surface
Use higher rates (10-20 lbs per acre of water surface) where extended residual control is necessary, or in habitats with deep water or dense surface cover. Apply uniformly by aerial and conventional ground equipment. Reapply as needed after 1-4 weeks. Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather related factors determine the potential spray drift. The applicator and treatment coordinator are responsible for considering all these factors when making decisions.
Environment: Wastewater, Storm Water/Drainage Systems, Marine/Coastal Areas, Water Bodies (natural and man-made aquatic sites such as lakes, ponds, rivers, canals, and streams) and Dormant Rice Fields.
Storage: Store in a cool, dry place.
