Why do mosquitoes bite some people more than others?

"Together with other scientists, Lindsay has debunked the myth that people with "sweet blood" are more prone to being bitten and found instead that mosquitoes are drawn to our unique "skin scent".

Researchers from Wageningen University in the Netherlands found that people who were highly attractive to malaria mosquitoes had a different bacterial community on their skin – more abundant, but less diverse – than those who were less attractive.

This may be because skin bacteria plays an important role in the production of human body odour, and without bacteria, human sweat is odourless to the human nose.
