SilMax Liquid Mosquito Film, A silicone-based non-toxic liquid product. SilMax is a liquid silicone which is very effective for controlling mosquito larvae and pupa in water. It spreads rapidly across the surface water - even large water bodies - and forms a very thin film. As silicons have a very low surface tension, the film presents pupae and larvae from attaching themselves at the surface while attempting to breathe, thereby causing them to saffocate and death as a result. It also discourages female mosquitos from laying egges on the surface. Hence the entire life cycle of the mosquito is interrupted. For more information about the product, please contact us.
