I don't think you all have Dengue or Malaria do you or the mosquitoes that carry them? If not why worry, there are harmless vegetation mosquitoes also. I think we have grown immune to bites. Funny thing that the females need blood in order to produce progeny. How ever much we try we cannot protect ourselves from everything so why degrade the quality of life. Enjoy and let the little beasties enjoy within certain limits.
