Bl00d Type Matters
Research has shown that blood type influences mosquito preference. People with type O blood are bitten more frequently, while those with type A tend to attract fewer mosquitoes.
Some individuals also release chemical markers through their skin that make their blood type easier for mosquitoes to detect.
Sweat, Lactic Acid, and Exercise
Mosquitoes are often more active around people who have been exercising. That’s because sweat and lactic acid, released through the skin, combine with higher body temperature.
This mix creates a powerful attraction, explaining why bites often increase after physical activity.
Clothing Color Can Increase Bites
Mosquitoes are highly visual insects. They are more attracted to dark colors such as black, navy, and red, which create stronger contrast.
Light-colored clothing reflects more light and tends to make people less noticeable to mosquitoes.
Alcohol, Hormones, and Fragrances
Studies suggest that alcohol consumption can increase mosquito attraction, possibly due to changes in body heat and metabolic byproducts.
Hormonal shifts such as during pregnancy, menstruation, or high stress can also alter body odor and increase attractiveness to mosquitoes.
Perfumes and skincare products may worsen the effect. Floral or fruity scents can mimic natural odors mosquitoes associate with food, while some cosmetics change skin pH in subtle but significant ways.
Genetics: The Factor You Can’t Change
Perhaps the most important factor is genetics. Scientists estimate that 60–70% of mosquito attraction is determined by DNA.
This explains why some people feel “cursed” with mosquito bites. In reality, it’s an inherited combination of chemical signals that mosquitoes find irresistible.
