How Gnats, no-see-ums, and mosquitoes find you

🧬 Why Bugs Are Drawn to You

Sand gnats, no-see-ums, and mosquitoes are expert trackers. They do not buzz around randomly. They are drawn to specific signals your body naturally releases.

When you breathe, you release carbon dioxide, which acts like a beacon for these biting insects. Your body heat, sweat, and natural skin scent also make it easier for sand gnats and mosquitoes to locate you.

Even subtle factors like lactic acid in sweat and the natural microbes on your skin can increase attraction. That is why some people seem to get bitten more than others. These insects use highly sensitive receptors on their antennae and mouthparts to follow scent trails directly to their target.

In warm, humid regions like Georgia and the Southeast, these conditions make outdoor activities especially attractive to sand gnats and mosquitoes.
