Why Do Mosquitoes Bite Certain People?
If you’ve ever felt like a mosquito magnet on a warm summer evening, you’re not imagining it. Some people really do get bitten more than others. But why? And is it true that things like your blood type or your diet determine your mosquito appeal?
We’re breaking down what attracts mosquitoes to people by unpacking five of the most common beliefs and offering up pro tips to help you better protect yourself, your family, your pets, and your home.
5 Popular Theories Explained & Pro Tips to Bite Back
Does blood type really matter to mosquitoes?
You may have heard that Type O blood attracts mosquitoes more than other types—and that’s partially true. But newer research shows that your natural skin odor, shaped by your genetics and microbiome, may play an even greater role. These scent compounds create a sort of invisible signature that can either attract or repel mosquitoes.
Pro Tip: While you can’t change your biology, you can avoid mixing in artificial scents that might amplify your appeal. Choose fragrance-free soaps and lotions, especially before spending time outdoors.
Do body heat and sweat make a difference?
Many people assume mosquitoes are drawn to sweat alone. But it’s the way sweat reacts with bacteria on your skin, creating scent compounds like ammonia and lactic acid, that sends a strong signal to mosquitoes. Add in body heat—especially after exercise or in warm, humid weather—and you’ve just increased your visibility.
What’s more, mosquitoes use heat as one of several targeting mechanisms. Even if you’re not sweating, higher body temperature makes you easier to locate.
Pro Tip: Rinse off after outdoor activity and opt for breathable, light clothing to help regulate your skin temperature.
Are mosquitoes attracted to specific colors of clothing?
Mosquitoes have surprisingly sharp vision and use contrast to spot their next meal. Dark clothing—especially black, navy, and red—makes you stand out more against natural backdrops. Research shows these colors are particularly attractive when mosquitoes are already tracking carbon dioxide and body heat.
Pro Tip: Opt for light-colored clothing when you’re spending time outside in the evening. Not only will it keep you cooler, but it will also make you less visually obvious to mosquitoes.
Can your diet make you more attractive to mosquitoes?
There’s no strong evidence that specific foods like bananas consistently make you more attractive to mosquitoes. However, certain beverages—especially alcohol—can increase your appeal. Research shows that beer in particular can raise your body temperature, change how your skin smells, and increase the carbon dioxide you exhale. All these factors make you a more attractive target.
Pro Tip: If you’re drinking alcohol outdoors, balance it with water and good airflow. Hosting guests? Strategically placing fans around gathering areas can help break scent trails and keep mosquitoes from honing in.
Why do mosquitoes bite pregnant people more often?
Mosquitoes don’t choose targets based on gender—they’re drawn to specific body cues and chemistry. Pregnant individuals, for instance, emit more carbon dioxide and tend to have higher body temperatures, both of which mosquitoes track.
Pro Tip: Mosquitos are typically most active in the early morning and early evening. Plan outdoor activities outside of peak mosquito hours, and swap standard bulbs for yellow “bug lights” in porch and patio fixtures to subtly deter mosquitoes in the short term.
How Mosquito Risks Add Up Around Maryland, DC & Virginia Homes
Warm, humid summers and a mix of outdoor living spaces like backyards, decks, patios, and porches make the Mid-Atlantic region especially mosquito-friendly. Add in frequent rainfall and areas of standing water (even as small as a bottle cap), and you’ve got perfect breeding conditions for these biting pests.
It’s not just about the nuisance; mosquitoes can carry and transmit serious illnesses like West Nile and Zika viruses.
Knowing what conditions attract mosquitoes and learning how to prevent them are essential for keeping your home and family protected.
