Scientific research is confirming what many suspect: mosquitoes demonstrably prefer some individuals over others. The attraction isn’t random; female mosquitoes are drawn to specific cues emitted by humans. Key factors include the carbon dioxide people exhale, their body odor – specifically, the unique blend of skin bacteria – and even genetics. Studies indicate that genetics account for up to 85% of the variation in mosquito attraction. Higher levels of certain acids on the skin, produced by skin bacteria, appear particularly enticing to mosquitoes. These findings could lead to more effective mosquito repellents tailored to individual body chemistries, offering better protection for those most vulnerable to bites.
