Mosquitoes Can Smell Your Personality – And They Judge You For It

Mosquitoes Can Smell Your Personality – And They Judge You For It

Mosquitoes aren’t just annoying—they’re strategic hunters that pick their victims based on factors you’d never expect. You’ve probably heard they’re drawn to carbon dioxide and body heat, but did you know your personality might also play a role in whether you get bitten?

Let’s break down some of the wildest, most scientifically backed mosquito facts that will make you rethink your next outdoor adventure.


1. Are You an Extrovert? Mosquitoes Love That!

If you’re an extrovert, you naturally move around more, talk louder, and breathe heavier—all things that make you more attractive to mosquitoes. Since mosquitoes use carbon dioxide (CO₂) as a primary tracking method (Lace et al., 2019), people who produce more of it tend to get bitten more often.

A study published in Current Biology (2015) found that mosquitoes locate their hosts by tracking CO₂ plumes from up to 50 meters away (Dekker et al., 2015). Extroverts, being more active and socially engaged, tend to exhale more CO₂ and generate more body heat—both major mosquito attractants.


2. Your Stress Levels Might Be a Mosquito Magnet

If you’re naturally anxious, mosquitoes might be targeting your stress hormones. Research suggests that increased cortisol levels (the hormone released when you're stressed) could influence mosquito attraction (Verhulst et al., 2018).

A study published in PLOS ONE found that human skin microbiota—bacteria on our skin that produce scents—changes with stress and can influence how attractive we are to mosquitoes (Verhulst et al., 2018). So, if you’re panicking about mosquitoes biting you, they might just bite you more!


3. Do Mosquitoes Have a Blood-Type Preference?

Yes, and science proves it. In a 2004 study published in The Journal of Medical Entomology, researchers found that mosquitoes prefer Type O blood over Type A, with Type B falling somewhere in between (Shirai et al., 2004).

What’s even weirder? About 80% of people naturally secrete a chemical marker through their skin that signals their blood type to mosquitoes (Shirai et al., 2004). If you're a Type O secretor, congratulations—you’re a walking buffet.


4. Alcohol Makes You More Delicious

Ever noticed mosquitoes biting more when you drink? That’s not just bad luck. A study in The Journal of the American Mosquito Control Association found that consuming alcohol—specifically beer—significantly increased mosquito attraction (Lefèvre et al., 2010).

Why? Scientists suspect it’s a combination of increased body temperature and changes in skin odor after alcohol consumption (Lefèvre et al., 2010). So, while you’re sipping that summer cocktail, mosquitoes are deciding you’re the perfect snack.


5. Mosquitoes Remember You

This is perhaps the creepiest fact of all: mosquitoes have memories and can learn to avoid certain people.

A 2018 study in Current Biology found that mosquitoes can be conditioned to associate certain human scents with danger—meaning if you swat at them enough, they might learn to avoid you in the future (Vinauger et al., 2018). Essentially, they can recognize specific people based on scent and previous encounters. Too bad they don’t warn their friends.


How to Make Yourself Less Appealing to Mosquitoes

Want to stop being a mosquito magnet? Try these science-backed solutions:

  • Wear light-colored clothing – Mosquitoes are drawn to dark colors (Muir et al., 1997).
  • Skip the perfume – Strong floral or fruity scents make you more attractive to mosquitoes (Logan et al., 2008).
  • Use a fan – Mosquitoes are weak flyers; a simple breeze can throw them off (Rowland et al., 2004).
  • Eat more garlic – Some studies suggest garlic compounds may help repel mosquitoes (Galeotti et al., 2012).

Final Thoughts

So, the next time you’re getting eaten alive, don’t just blame bad luck—blame your personality, stress levels, and even your choice of drinks. Mosquitoes are tiny flying assassins that track you based on science, and now you know their secrets.

Would you rather be a mosquito magnet or invisible to them?
