VectoBac DT (U.S.) is a direct tablet formulation of Bacillus thuringiensis subsp. israelensis (strain AM65-52) for control of container-breeding mosquito larvae. The product has a potency of 2,200 International Toxin Units (ITU) per milligram against Aedes aegypti larvae. VectoBac DT consists of only Bti (strain AM65-52) and food-grade (US EPA list 4) inert ingredients.
VectoBac DT is intended for residential use. Do not apply directly to treated, finished water supply systems, as these systems are not considered mosquito breeding sites. For use in artificial containers used for water collection to control container mosquitoes (e.g. Aedes aegypti, Aedes albopictus). Artificial water containers may include drums, storage tanks, jars, rooftop catchments, ornamental fish ponds, ornamental pools or fountains, unused swimming pools, floor drains, and roof gutters.
Suggested Application Rate:
1 tablet per 13.2 gallons (50 L).
Reapply at monthly intervals as needed (when late-stage larval numbers return to pre-treatment threshold levels)
