How Safe is a Mosquito Net?
WouterUsing a mosquito net is a great way to protect yourself and your family from mosquito-borne diseases. The World Health Organization recommends using insecticide treated nets to help prevent malaria.
These insecticide-treated nets are the mainstay of the global malaria fight. They provide two levels of protection: an instant kill and a mechanical barrier. They have been shown to reduce the number of malaria cases by more than half. They are also effective against other diseases.
However, recent years have seen an increase in insecticide-resistant mosquitoes. This can be a concern for those living in tropical countries. Luckily, scientists are developing new types of insecticides.
The main ingredient in these insecticide-treated nets is a substance called pyrethroids. Pyrethroids are extracts from the African flower Chrysanthemum cineriaefolium. They are a safe, proven insecticide. They have been used in public health for decades.
Unlike some pesticides, pyrethroids are not harmful to humans or pets. They are also the only insecticide recommended by the World Health Organization for use on mosquito nets.
Another interesting fact about insecticide-treated nets is that they are still 90% effective when there are small holes in the fabric. This may not be true for all brands of insecticide-treated nets. But the general consensus is that they are more effective at preventing malaria than untreated nets.
The latest technique for combating resistant mosquitoes weaves a new chemical into the net itself. The chemical breaks down mosquitoes’ ability to resist the insecticide.
