Mosquito bites aren’t random: some people are more attractive to mosquitoes due to body odor and skin chemistry, plus factors like carbon dioxide, heat, and skin microbiome can influence bite risk. Here’s a concise update and practical tips.
Latest context
- Recent reporting continues to reinforce that certain people are “mosquito magnets” because their skin emits specific chemicals that mosquitoes use to locate hosts. This phenomenon has been observed across multiple studies and outlets, with one well-cited finding pointing to higher levels of certain fatty acids on the skin as a key attractant.[1][3][4]
Why some people attract more mosquitoes
- Body odor: The composition and quantity of skin-emitted chemicals, including fatty acids, help mosquitoes identify targets.[5][1]
- Carbon dioxide and heat: Everyone exhales CO2 and has surface heat; some people emit those cues more strongly, increasing attraction.[3]
- Skin microbiome: The bacteria that live on your skin metabolize skin secretions and create odor profiles that can be more appealing to mosquitoes.[1]
What you can do now
- Use EPA-registered repellents (DEET, picaridin, IR3535, oil of lemon eucalyptus) consistently when outdoors, especially at dawn/dusk or in high-risk areas.[3]
- Dress to reduce exposed skin: long sleeves/pants, light colors, and consider permethrin-treated clothing for outdoor activities.[6]
- Minimize attractive cues: avoid heavy alcohol consumption before outdoor time, stay in shaded or breezy areas, and choose venues with good airflow when possible.[3]
- Reduce standing skin moisture and odors after sweating: shower and dry thoroughly; consider fragrance-free products to avoid masking repellent effectiveness.
Illustrative note
- Research shows the “mosquito magnet” effect tends to be stable over time for individuals, suggesting some people consistently attract more bites due to their natural odor profile.[1]

Next, scientists looked at the chemicals that each person’s body was producing. They learned that the people whose scent the mosquitoes liked produced more of a certain chemical. Scientists call these people “mosquito magnets.” People can’t change how much of a chemical their bodies make. But scientists say it’s helpful to know what mosquitoes are attracted to. It could lead to the development of more products that are meant to keep mosquitoes away.
