The PermaNet® technology developed by Vestergaard Frandsen, and patented in many countries, 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® Long-lasting Insecticidal Nets (LNs) and Net Curtains prevent the threat of vector-borne diseases such as Malaria, Dengue, Leishmaniasis, Filariasis and Chagas.
