Here’s why mosquitoes go for some folks more than others

Skin bacteria: The community of microbes on your skin affects how your natural odors smell to mosquitoes. Some bacteria produce odors that are especially attractive to mosquitoes.

Interestingly, everyone’s chemical signature is unique, which is why some people are consistently targeted while others are mostly ignored.

4. Blood Type: The ABO Advantage
Yes, your blood type can affect mosquito attraction. Research shows that mosquitoes prefer Type O blood over A, B, or AB. One study found that people with Type O blood were twice as likely to be bitten as those with Type A.

Why does blood type matter? Mosquitoes detect chemicals secreted through your skin that correlate with your blood type. Even if you don’t know your blood type, your skin may be broadcasting it every time you step outside.

5. Genetics and Inherited Factors
Your susceptibility to mosquito bites is also influenced by genetic factors. Genes determine your metabolism, sweat composition, and even the makeup of your skin microbiome. This means that your parents’ biology can play a role in how appealing you are to mosquitoes.

For example:

People with higher basal body temperatures or faster metabolisms tend to attract more mosquitoes.

Certain gene variants affect how your skin produces chemicals that mosquitoes find enticing.

In essence, some people are genetically “mosquito magnets,” while others are naturally less appealing.

6. Pregnancy and Hormonal Influences
Pregnancy increases mosquito attraction, not just because of CO₂ but also due to hormonal changes. Pregnant women produce more blood and have higher body temperatures, creating a more inviting environment for mosquitoes. Additionally, hormonal shifts may subtly alter skin chemistry, making them even more noticeable to these tiny hunters.

7. Alcohol Consumption and Diet
What you consume can also influence mosquito attraction:

Alcohol: Studies have found that drinking beer or wine can increase your attractiveness to mosquitoes. The exact mechanism isn’t fully understood, but alcohol may raise body temperature and alter sweat composition.
