As Bs grows, it produces binary toxin, Mtx and Cry48Aa/Cry49A, which have specific toxic effects on a variety of mosquito larvae. It is hence widely used in biological vector and mosquito control and considered a larvicidal solution that is non-toxic to human, animal, poultry and aquatic life and environmentally friendly.
