Mosquito season is upon us and for some people, that means intense discomfort.

In All in a Day this week, CBC Radio's science columnist Torah Kachur explains that the reason why mosquitoes love to bite is because they need a blood meal to get the necessary nutrients for their larvae to mature.

But they're selective when choosing their victims. Recent studies indicate that mosquitoes prefer pregnant women and larger size people. They also tend to feed on adults more than they do on children.

Torah Kachur delves into who else is at risk of being bitten — and why.
