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

🧬 Why Bugs Are Drawn to You

Gnats, no-see-ums, and mosquitoes are expert trackers. They don’t just buzz around aimlessly—they’re drawn to specific cues your body gives off. When you breathe, you release carbon dioxide, which acts like a beacon for these bugs. Combine that with body heat, sweat, and natural skin odors, and you’ve basically sent out an open invitation.

Even subtle things like lactic acid in sweat or the microbes on your skin can attract biting insects. That’s why some people get swarmed more than others—it’s a real, biological hunt. Gnats and mosquitoes follow these scent trails using specialized receptors on their antennae and mouthparts.
