The potency of VectoLex FG is 50 Bs International Toxin Units (Bs ITU) per milligram against Culex quinquefasciatus larvae. VectoLex FG offers extended control of all Culex species and has been found to be effective against the following species:

  • Aedes melanimon
  • Aedes nigromaculis
  • Aedes sollicitans
  • Aedes stimulans
  • Aedes triseriatus
  • Aedes vexans
  • Anopheles darlingi
  • Anopheles gambiae

Where and When to Use VectoLex® FG:

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


Features of VectoLex FG:

  • Dry formulation
  • Highly specific activity on select mosquito species
  • Works extremely well in polluted waters
  • Provides the industry’s most target-specific biorational for residual control of West Nile virus vectors
  • The microbial mode of action allows for easy, on-site efficacy evaluations
  • VectoLex’s fermentation consistency and pharmaceutical-grade standards significantly reduce lot-to-lot variation relative to other manufacturers, providing greater peace of mind

Benefits of VectoLex FG:

  • Increased storage shelf life
  • Not harmful to non-target organisms
  • Results assessed quickly in field

Mode of Action:

The larvae ingest the insecticide, consisting of Bs spores produced by the bacteria. Only when activated by the larva’s specific gut PH and enzymes, do the spores become toxic, causing damage to the gut of the mosquito. Mortality rate is dependent on consumption of the Bs by 1st through early 4th instar larvae. The product is quick acting and highly effective against a number of mosquito species and its long term residual makes it ideal for use in a wide number of permanent aquatic habitats.
