According to multiple studies, mosquitoes are more attracted to certain blood types than others. Here is what the research says:

• Mosquitoes are most drawn to type O blood, followed by type B blood.
• Mosquitoes are least attracted to type A blood.
• People with type O blood are more likely to be bitten by mosquitoes than those with type A blood.
• Mosquitoes detect blood types through chemical signals secreted through human (and animal) skin.

It is important to note that blood type is not the only factor that attracts mosquitoes. Other factors that can make a person more attractive to mosquitoes include body odor, heat, dark clothing, and carbon dioxide emissions. To reduce the risk of mosquito bites, people can use mosquito repellents, avoid outdoor activities when mosquitoes are most active, and wear light-colored clothing.
