Why Some People Are More Attractive to Mosquitoes

Introduction

Ever wonder why mosquitoes seem to swarm around certain people while others barely get a bite? Science shows that it’s not your imagination — mosquitoes are indeed more attracted to some people than others. This isn’t random; it’s influenced by body chemistry, skin bacteria, and even the way you breathe.

Key Factors That Attract Mosquitoes

Carbon Dioxide (CO₂): Mosquitoes are drawn to the carbon dioxide you exhale. People who exhale more (such as larger individuals or those exercising) tend to attract more bites.

Body Heat: Warmer skin temperatures can make you more noticeable to mosquitoes.

Skin Chemistry: Natural body odors and compounds, like lactic acid from sweat, can lure mosquitoes.

Blood Type: Studies suggest people with Type O blood are more attractive to mosquitoes than those with other blood types.

Skin Bacteria: The unique blend of bacteria on your skin creates subtle odors — some combinations are irresistible to mosquitoes.

Pregnancy: Pregnant women exhale more CO₂ and have higher body heat, making them especially attractive to mosquitoes.

Alcohol Consumption: Drinking beer has been shown in some studies to increase mosquito attraction.
