Mosquito Nets


Mosquito nets are a very useful and practical way to prevent insect bites. There are a number of things to keep in mind when buying a mosquito net.

The mesh size should be large enough for air circulation but as small as possible to keep out the mosquitoes. A mesh size of 1.2 mm x 1.2 mm is the most common and recommended. For effective malaria protection, the mesh size that is recommended is 120-200 holes per square per inch.

Mosquito nets of polyester or polyamide are usually lightweight, long-lasting nets, and are available in different mesh sizes and thread thickness. On the other hand, cotton is susceptible to dampness, and weighs more when wet.

As for the shape of the net, it should obviously be wide enough to cover the person sleeping, without touching them. Rectangular nets offer more room around the person as opposed to the slanted sides of a tent or pyramid shaped net. Either way, the net should be tucked under the mattress. You can use screws, tacks, pins, or hooks to attach the upper point of the net above the bed. Pillows or blankets can be used to build a makeshift wall around the body to avoid touching the net. It is much more efficient to purchase a net that has already been dipped or sprayed with a high quality insecticide such as permethrin. The nets are pre-treated at the netting manufacturing plant and can last up to a year depending on the amount of exposure to sun and rain.
