I am a mosquito magnet. Seriously, even during dry season, they will bite me in bright sunlight. The only thing that works for me is the Sportsman's Off... 100% DEET. Yeah, I know it's not good for you, and I shower it off every night, but I don't leave the house without it. I also have a really bad reaction to the bites, so that makes it even worse. Seashell is right, the other stuff works, but not for long, and it takes a bite to let you know that it has stopped working. They lick that stuff off me as an appetizer and then eat away. Castillo's Hardware used to sell this Off product back in their lawn and garden section. Be careful though and wash your hands thoroughly after you apply it and be warned that it will melt plastic, take off varnish and nail polish. But it's the only thing that has worked for me.
