You know the feeling. You're sitting outside on a warm summer evening, and while everyone else chats away untouched, you're the one slapping at your arms and legs all night. It's not your imagination — some people really do get bitten more than others.
So what makes you the main course? It comes down to a mix of biology, habits and even what's in your glass. Here's what actually draws mosquitoes in.
Your breath is basically an invitation
Every time we exhale, we release carbon dioxide — and more of it when we're active, like during a workout. Mosquitoes are remarkably good at detecting changes in CO2 in the air around them. To them, it's a signal that a potential meal is nearby.
Once they pick up the trail, they start heading straight for the source. The same goes for body heat. The moment they sense the warmth of a living body, they move in closer.
It's partly in your genes
Mosquitoes are strongly drawn to certain compounds found on human skin and in sweat.
These substances practically hypnotize a hungry mosquito. And your personal scent? That's largely determined by genetics. A study published in 2015 found that mosquitoes were strongly attracted to the smells of identical twins. The same research also showed something reassuring: people whose skin hosts a wide variety of microbes tend to be less appealing to mosquitoes.
Dark clothes make you a bigger target
Research has shown that mosquitoes are drawn to the color black — though nobody knows exactly why. Either way, if you're wearing black or another dark shade, you'll be more attractive to them.
Mosquitoes aren't exactly geniuses. They're probably not hiding behind the curtains waiting for you to fall asleep. But on some level, they can learn. They're able to associate certain smells with particular hosts and their blood. That way, they don't have to search and try as much to find a good meal — they simply zero in on the scent they've already learned.
If you're curious about gentler ways to keep the bites down, it's worth exploring simple home remedies that soothe mosquito bites.
The beer connection
People who've been drinking alcohol are more appealing to mosquitoes, too. And here's the surprising part: research has found that beer drinkers get bitten more readily than people who've been sipping something else.
So here's a slightly cheeky tip. If you haven't had a beer but you feel like you're under attack, strike up a conversation with someone holding a pint. Between the two of you, they'll suddenly be the more tempting target.
Pregnancy makes a difference
Expecting mothers don't get a free pass either. Mosquitoes are more attracted to pregnant women than to those who aren't expecting. The likely reason: pregnant women tend to have a slightly higher body temperature and exhale more carbon dioxide. Both are exactly what draws the little bloodsuckers in.
The best ways to ease a mosquito bite
If a mosquito has already gotten to you, there are a few quick ways to calm the swelling and itching. First and most importantly: try not to scratch. Scratching only makes it worse.
Place something cold or a damp compress on the bite. And if you don't have a pharmacy cream on hand, a little lemon juice or even a used tea bag can bring surprising relief.
Most mosquito bites fade within a few days. But if a bite swells badly or you notice other symptoms — like fever or a headache — see a doctor right away.
One last thing you may not know
Here's a fact that catches most people off guard: only female mosquitoes actually feed on blood. They need it to reproduce. After a female bites you, she can produce and lay her eggs in a nearby puddle or any patch of water — even a glass of water will do. When she's ready to reproduce again, she needs another blood meal.
Male mosquitoes, on the other hand, don't drink blood at all. They live on nectar and the juices produced by plants.
Why do mosquitoes bite some people more than others?
It comes down to a combination of factors: the carbon dioxide you exhale, your body heat, the compounds in your sweat, your genetics, and even the color of your clothes. Some people simply give off more of the signals mosquitoes are looking for.
Does drinking beer really attract mosquitoes?
Yes. Research has found that people who drink beer tend to get bitten more readily than those who've been drinking something else, though the exact reason isn't fully understood.
Why are pregnant women bitten more often?
Pregnant women usually have a slightly higher body temperature and exhale more carbon dioxide, and both of those signals strongly attract mosquitoes.
What's the fastest way to soothe a bite?
Avoid scratching, then apply something cold or a damp compress. If you don't have a pharmacy cream, a little lemon juice or a used tea bag can help ease the itch.
