All of our mosquito nets have gained international approvals from UNICEF (United Nations International Children's Emergency Fund) and the WHO (World Health Organization). According to the latter agency's recommendation, the nets we offer can be impregnated with pyrethroid for extra protection against malaria and other vector-borne diseases.
A mosquito net offers protection against mosquitoes, flies, and other insects, and thus against diseases such as malaria. Its fine, see-through, mesh construction stops many insects from biting and disturbing the person using the net. The mesh is fine enough to exclude these insects, but it does not completely impede the flow of air.
Mosquito nets are often used where malaria or other insect-borne diseases are common, especially as a tent-like covering over a bed. For effectiveness, it is important that the netting not have holes or gaps large enough to allow insects to enter. Because an insect can bite a person through the net, the net must not rest directly on the skin.
Mosquito nets treated with insecticides-known as insecticide treated nets (ITNs) -- were developed in the 1980s for malaria prevention. These nets, impregnated with a pyrethroid insecticide like deltamethrin or permethrin, kill and repel mosquitoes. Unfortunately, standard ITNs must be replaced or re-treated with insecticide after six washes and, therefore, are not seen as a convenient, effective long-term solution to the malaria problem.
As a result, the mosquito netting and pesticide industries teamed up to develop so-called long-lasting insecticidal mosquito nets (LLINs), which also use pyrethroid insecticides. There are two types of LLINS, one which binds insecticide to the external surface of the netting fibre and another which incorporates the insecticide into a polyethylene fibre which then releases the insecticide slowly over 5 years. Both types can be washed at least 20 times but physical durability will vary with polyethylene lasting the longest
