The PermaNet® technology developed by Vestergaard Frandsen manages the challenging task of controlling the slow release and migration of the insecticide coated on the surface of the yarn. This is precisely what makes the PermaNet® tools "long-lasting" ensuring that the insecticide is always present at the surface of the net, even after multiple washes and years of use.

PermaNet® LLIN and Curtains are both insecticide-treated tools that can together prevent the threat of vector-borne disease such malaria, dengue, chagas, filariasis and leishmaniasis.

PermaNet® factory-treated tools are environment-friendly as they reduce insecticide consumption over the lifetime of the product.
