If you feel like mosquitoes always make a beeline for you, it’s not just in your head. Some people really are more attractive to mosquitoes, and it's not only due to bad luck. In Houston’s hot, humid climate, understanding what draws mosquitoes to you is a smart first step toward reducing those itchy bites.

Here are the top five reasons mosquitoes might be targeting you and what you can do to turn the tables.
1. You Might Have Blood Type O
Research shows that mosquitoes may be more attracted to individuals with blood type O, especially those who are “secretors,” meaning they emit blood type markers in their saliva and sweat. These antigens might signal to mosquitoes that you’re a prime target.
While this isn't the only factor that matters, studies from 1974 and 2019 support the idea that mosquitoes tend to land more frequently on people with blood type O than type A.
Tip: If you have type O blood, it’s a good idea to be extra cautious during mosquito season. Using EPA-approved insect repellent, wearing protective clothing, and limiting time outdoors during dawn and dusk can help reduce your chances of getting bitten.
2. You Exhale More Carbon Dioxide
Mosquitoes are expert hunters when it comes to detecting carbon dioxide (CO₂). The more you exhale, the more likely you are to attract them. People who breathe more heavily, such as those who are physically active, pregnant, or have a higher metabolic rate, naturally emit more CO₂, which mosquitoes use like a trail leading directly to you.
Tip: To counteract this, try to avoid strenuous outdoor activities during peak mosquito hours. Creating air movement with fans on patios can help disperse CO₂ and make it harder for mosquitoes to locate you. And if your yard is a constant mosquito hotspot, professional mosquito treatments can make a major difference.
3. You Smell Appealing (to Mosquitoes)
Your unique body chemistry might be attracting mosquitoes more than your neighbors. A scientific study shows that compounds like lactic acid and ammonia, which are naturally present in sweat, can make you more enticing to mosquitoes.
Additionally, according to a 2011 study, the bacteria on your skin play a big role. People with a high abundance but low diversity of skin bacteria tend to be more attractive to these pests. Even genetics has an impact, as mosquitoes have shown a preference for identical twins over fraternal twins in a heritability study, suggesting that your scent may be hardwired.
Tip: If you seem to get bitten more than others, consider switching to fragrance-free soaps and lotions, and avoid sweet-smelling body products during mosquito season. Reducing strong scents may help lower your mosquito appeal.
4. You Radiate Heat
Mosquitoes are not just drawn to smells and carbon dioxide. They’re also heat-seeking. Female mosquitoes in particular are known to fly toward warmer areas, and your body’s natural temperature makes you a target. People who tend to run warm, are physically active, or spend time in the sun may be more appealing to mosquitoes. That’s why these pests often go for heat-rich areas like ankles, wrists, and the neck.
Tip: To minimize this attraction, try staying in the shade during peak mosquito activity, wear light-colored and breathable clothing, and take breaks to cool down if you spend time outside.
5. You’re Wearing the Wrong Colors
Believe it or not, your wardrobe might be making you a mosquito magnet. Mosquitoes are more attracted to darker colors, predominantly black. While researchers are still studying the exact reasons, it’s likely that dark clothing retains more heat and provides higher contrast, making it easier for mosquitoes to spot you.
Tip: To help avoid this, wear white, light gray, or pastel-colored clothing when spending time outside. Loose, breathable fabrics also reduce the amount of skin exposed, which can cut down on bites.
Take Control Before Mosquitoes Take Over
Being a mosquito magnet can be frustrating, but knowing what makes you more attractive to these pests can help you take practical steps to avoid them. Even with all the right precautions, though, Houston’s mosquito population can still make your outdoor spaces uncomfortable.
