Aquatain AMF® is a liquid silicone-based liquid that forms a thin film on stagnant water bodies. It works in several ways, partly because the liquid silicone-based membrane prevents mosquito larvae and mosquito pupae from getting through the water surface to reach air. The eggs die and the membrane prevents the female mosquito from laying new eggs in treated water collections. This prevents mosquitoes at all stages from developing and reproducing in an environmentally friendly way.
