No, mosquitoes are more attracted to type O blood than type A blood. While mosquitoes do show a preference for certain blood types, type O is generally considered their preferred choice. Type A blood is less attractive to mosquitoes compared to type O.
Several studies suggest that blood type influences mosquito attraction, but the effect is not absolute. Other factors, such as carbon dioxide exhalation, body temperature, and even clothing colors, also significantly affect whether a mosquito chooses to bite a person.
Key Findings from Research:
- Type O is preferred: Multiple sources indicate that mosquitoes show a stronger preference for individuals with type O blood. Dr. Ulysses Wu states that "Type O blood seems to be a mosquitoes' preferred blood type as compared to A, B and AB, but the only significant difference was when it was compared to Type A."

- Type A is less attractive: While not completely avoided, type A blood is demonstrably less attractive to mosquitoes than type O.
- Other factors influence attraction: Blood type is only one factor determining mosquito bites. Other elements such as carbon dioxide levels, body odor, and body temperature also play significant roles in mosquito attraction.

In Summary: Although mosquitoes do exhibit a preference for specific blood types, they are less likely to choose type A over type O. However, other factors are equally, if not more, important in determining an individual's attractiveness to mosquitoes.
