Mosquitoes are attracted to different people depending on the levels of carboxylic acids in their skin. Researchers had participants wear nylon stockings to collect their skin emanations. The stockings were then exposed to mosquitoes to see which ones they were attracted to most. The results showed mosquitoes were more attracted to stockings from people with higher levels of carboxylic acids like pentanoic acid and heptanoic acid coming from their skin.
