They say mosquitos are attracted to fragrant soaps/lotions/perfumes, so avoid those things. Also avoid wearing bright colours during prime mosquito hours.

I'm one of those people that mosquitos are attracted to, unfortunately. I can go running at night and come home with 5 mosquito bites, and my boyfriend won't get a single one.

Pulled this off the internet:

Some studies suggest that taking thiamine (vitamin B1) 25mg to 50 mg three times per day is effective in reducing mosquito bites. This safe vitamin apparently produces a skin odor that is not detectable by humans, but is disagreeable to pregnant mosquitoes (Pediatric Clinics of North America, 16:191, 1969). It seems to be especially effective for those people with large allergic reactions. Thiamine takes about 2 weeks before the odor fully saturates the skin.
