It’s not just popular imagination: mosquitoes bite some people more than others. We don't really understand why, but a recent paper in PLOS One suggests that genes could play a role in the attraction.
We’ve known for a while that smell is at least a partial explanation for why some people are mosquito fodder while others return from the outdoors unscathed. A number of different studies have found that differences in body odor are related to interest from mosquitoes. What we don’t properly understand is what causes those differences in smell.
A widespread myth is that certain foods can repel or attract mosquitoes, but there’s no clear explanation for how diet could change attraction levels, write the authors of the new study. What evidence we have seems to lean away from food as a factor. This makes sense: if mosquitoes use smell to find a suitable meal, they’d evolve to sniff out stable smells, not smells that change with every meal.

I don't think they "won't" bite some people, I know that when I am out, I'm the target - always have been. But if I go inside and there are others outside, someone else becomes the target - so I think in their mind, they merely see some of us as the tastier morsel and make do with the slops if we aren't around.
