Whilst the application of Mozzie & Midge Barrier surface film results in the eventual death of mosquito & midge larvae, this product is not considered a larvicide, given the substance does not directly alter the organism’s physiology. It merely prevents the larvae from breathing and they die and fall to the bottom of the tank.
