Flies and insects are an important part of the ecosystem. Unfortunately, they are also gifted at being huge nuisances. But not just that. Mosquitoes in particular can trigger allergic reactions in humans or even transmit disease. Most people prefer insects to stay where they belong – outside. While you can keep mosquitoes and flies out of your home with a fly screen, a mosquito net ensures that you can sleep in peace and wake up without any mosquito bites.
