A night when you shared a room yet seemed to be the only one bitten. Knowing the cues mosquitoes use can offer another perspective. Rather than attributing it to one body type or odor, explore several cues and your surroundings.

The many cues mosquitoes follow

Carbon dioxide from breathing, odors released by skin, and nearby heat and visual cues: research describes mosquitoes using these together to locate hosts. Not every species follows the same sequence at the same distances every time.

Individual differences in skin odor are also studied. A 2022 Cell paper studied Aedes aegypti and reported differences in attraction between people, associated with levels of skin-derived carboxylic acids. These findings should not be generalized to every species or every person's reason for being bitten.

Individual differences discussed in the interview

Professor Hyung Wook Kwon's interview discusses children not noticing approaching mosquitoes, and how preferred body areas can vary by species. The images below quote the original interview.

A bite's location alone cannot identify its cause. Exposed skin, window screens, surroundings and mosquito species can all matter. Before concluding that you have a 'mosquito-attracting constitution,' check your environment.
