Mosquitoes are attracted to certain blood types, but its not the only factor that influences their preference. According to several studies, mosquitoes may prefer people with type O blood over those with other blood types. However, the difference is not significant when compared to other blood types. Other factors that can make a person more attractive to mosquitoes include:

• Body odor: Mosquitoes are attracted to the chemicals that people secrete through their skin, such as lactic acid.

• Carbon dioxide: Mosquitoes can detect carbon dioxide from a distance and are attracted to people who exhale more of it, such as those who are exercising or have a high metabolic rate.

• Heat: Mosquitoes are drawn to heat, so people with higher body temperatures are more attractive to them.

• Dark clothing: Mosquitoes use vision to locate humans, and wearing dark-colored clothing can make a person easier to find.

• Genetics: Underlying genetic factors are estimated to account for 85% of the variability between people in their attractiveness to mosquitoes, regardless of whether its expressed through blood type, metabolism, or other factors.

In conclusion, mosquitoes may prefer people with type O blood, but other factors such as body odor, carbon dioxide, heat, and clothing color can also make a person more attractive to them.
