Why do mosquitoes bite some people more than others? You have surely noticed that, being surrounded by mosquitoes, insects seem to bite you much more often than your companions.

They observed which of the two participants suffered fewer bites and wrapped him in aluminum foil to collect his sweat.

Using a technique known as chromatography-electroantennography (GC-EAG), they were able to separate the individual’s “perfume” into its chemical components and test the mosquitoes’ reaction to each of them.

It is still unknown why some people produce these repellent chemicals naturally, while others do not.

The research results were published in The Royal Society.
