It instantly spreads an invisible monomolecular film over the water. This film reduces the surface tension of the water and makes it difficult for the larvae and pupae to attach. The film also blocks their breathing tubes and the larvae and pupae drown. Resting males and egg-laying females that come in contact with the film will also drown.
Mosquito control begins minutes after application.
Laboratory and field testing has shown the film to remain potent for 10 to 14 days on standing water. When the correct amount has been applied, there will be no breaks or gaps in the film from which mosquitoes can emerge. This ethoxylate, a surfactant that has been in use in various applications for over twenty years, has no known adverse health or environmental effects. Because it will spread across the waters' surface and through water vegetation, labor costs for application are reduced. It is highly unlikely the larvae or pupae stages could develop resistance.
