How annoying they are, though, varies from person to person. As part of the study, Florida International University pitted 119 humans against three mosquito species and found no one person was attractive to all three species. For the Asian Tiger mosquito species, which is well established across the Southeast, the Mid-Atlantic, parts of the Midwest, Hawaii, and localized areas of California, researchers found it was associated with the presence of attractive odors. This study, specifically, just associated a person’s microbiome and odors with mosquito attraction. However, it noted the initial research and additional findings could eventually help scientists develop new mosquito repellents that manipulate microbes or odors that mosquitoes use to find hosts.
