Mosquitoes' Taste: Science Unlocks Human Scent Secrets
12 May
Summary
- Mosquitoes are attracted by body odor, heat, and exhaled carbon dioxide.
- A specific skin oil breakdown compound is highly attractive to mosquitoes.
- Drinking beer increases attractiveness to mosquitoes by 1.35 times.

Research is actively progressing in understanding the complex chemical signals that make specific people more appealing to mosquitoes. Female mosquitoes, the ones that bite, are finely tuned to detect sensory cues such as body odor, heat, and exhaled carbon dioxide to select their targets.
Contrary to popular belief, the idea that mosquitoes prefer certain blood types lacks scientific basis. Instead, the "soup of molecules" produced by our skin's microbiota is a major attractor. A recent laboratory study involving Aedes aegypti mosquitoes identified 27 distinct odorous compounds, finding that a compound resulting from the breakdown of sebum, a skin oil, was a significant attractant.
Furthermore, several studies suggest that consuming beer increases a person's attractiveness to mosquitoes. This is attributed to several factors, including elevated body temperature, increased carbon dioxide exhalation, and altered skin odor. A 2023 study in the Netherlands found volunteers who had drunk beer in the preceding 24 hours were 1.35 times more appealing to Anopheles mosquitoes, which are known carriers of malaria.
