What is the best way to kill mosquitos and to keep them from feeding on you?

I live in a normally very dry,desert climate, and have recently been swarmed by a slew of mosquitoes. Lately, it has been so dry that I have been filling my 10 gallon fish tank up every day since the water level drops ½ inch to an 1 each day. There has been no rain and there is no standing water anywhere in my backyard, yet the nasty buggers are everywhere. The worst part is they have infiltrated my home and taken a particular liking to my blood in particular. I’m am quite afraid of contracting West Nile Virus and have gone to such extremes as plugging in a bug zapper in my bathroom! Any suggestions are quite welcome on how best to remedy these issues!
