Bacillus thuringiensis israelensis (Bti) Biological Larvicides
Bti is a biological or a naturally occurring bacterium found in soils. (Bti is short for Bacillus thuringiensis subspecies israelensis.) It contains spores that produce toxins that specifically target and only affect the larvae of the mosquito, blackfly and fungus gnat. EPA has registered five different strains of Bti found in 48 pesticide products that are approved for use in residential, commercial and agricultural settings primarily for control of mosquito larvae.
Bti is used across the United States for mosquito control. Bti is approved for aerial spraying, which has taken place in Massachusetts, Pennsylvania, Maryland and Michigan, among other states. Bti can be sprayed over waterbodies such as ponds, lakes, rivers and streams. Bti is used to kill developing mosquito larvae by being applied to standing water where those larvae are found. Bti can be used around homes in areas and containers where water can collect, such as flower pots, tires, and bird baths. Bti can also be used to treat larger bodies of water like ponds, lakes and irrigation ditches.

VectoBac G, GS (formerly CG), and GR are granular formulations of Bacillus thuringiensis subsp.israelensis (strain AM65-52) for control of mosquito larvae.
AquaBac 200G Granular Bacillus thuringiensis var. israelensis (Bti). Bti is eaten by the mosquito larva and becomes highly toxic to the larva killing them within minutes after ingestion. Since the bacteria are harmless to other mosquito and black fly larva predators, these predators continue to feed on the larva and work in concert with Bti to keep the larva population in check.
