From the BBC, now you know why you can't get away:
All together, the team developed a three-stage picture of the mosquitoes' hunting strategy:
■From distances of 10-50m they use smell, particularly CO2
■If already aroused by a smell, they will head for something visually interesting - this has a range of 5-15m
■Once within 1m of a potential target, they zero in on body heat
From the perspective of the mozzies' human victims, this three-pronged approach is "annoyingly robust", Dr van Breugel said.
"The unfortunate conclusion is that it's very difficult to escape mosquitoes.
"If you were able to capture all the CO2 that you were breathing out, then it'd be less likely that a mosquito would find you. But then if you were in a group of people, and somebody else wasn't taking those precautions, then a mosquito would follow their CO2 plume. And it may end up finding you before it finds your friend.
