Bacillus thuringiensis isrealensis (Bti) is a biological control agent which is naturally occurring and can be found in soil and aquatic environment throughout the world. At the time of sporulation, Bti produces a highly specific delta-endotoxin which is only toxic to larvae of mosquitoes, black flies, midges and fungus gnats.
