PermaNet® 2.0 Long-Lasting Insecticidal Net (LN)
The PermaNet® technology, developed by Vestergaard Frandsen, manages the challenging task of controlling the slow release and migration of the insecticide impregnated in the yarn to the surface of the net. This is what makes the PermaNet® tools “long-lasting,” ensuring that the insecticide is always present at the surface of the net, even after washing and several years of use.
The need for long-lasting tools for the prevention of vector-borne diseases arose as the majority of net owners did not re-treat their nets after the stipulated period of time, thus rendering the tool ineffective in repelling and killing mosquitoes, and subsequently increasing the risk of the user contracting diseases like Malaria and Dengue.
The PermaNet® technology is unique as it enables one to wash the nets and curtains without any loss in the effectiveness in killing mosquitoes and without requiring re-treatment during its specified lifetime.
Vestergaard Frandsen uses its PermaNet® technology to combat malaria as well as many of the neglected tropical diseases (NTDs) such as Dengue, Leishmaniasis, Chagas disease and Lymphatic Filariasis (Elephantiasis), which exact a high social and economic toll on the affected populations causing physical incapacitation that limits school attendance and impairs work productivity in African, Asian as well as South and Central American countries.
PermaNet® long-lasting insecticidal bednets (LNs) and PermaNet® net curtains provide efficacious vector control to reduce the transmission of various vector-borne diseases. While PermaNet® bednets kill and repel night-biting mosquitoes, users are protected from the day-biting vectors by PermaNet® net curtains. Thus, both of these tools compliment each other as they provide ‘day and night’ protection from disease-transmitting vectors.
