I find myself very safe when I am inside mosquito net because neither is  there any side effect of mosquito net nor there is any big investment. Once you buy it you can use it for many years. I even suggest my friends that if they want to enjoy sound sleep with no disturbance then they must use mosquito net. It is different thing that modern people do not want to use it because for them so many options are available in the market , they only have to keep spending money and they can enjoy sleep without disturbance. All know very well that there are many side effects of sprays etc. which are used to get rid of mosquitos but who cares. A very simple answer is there , when everything is harmful then let this also show its harm. Actually mosquito net is old fashioned and those who love freedom for them it is not a good solution as they feel suffocated when they sleep inside the mosquito net.
