Yes — Some People Really Are Mosquito Magnets
If everyone is sitting on the same patio and one person is getting hammered while everyone else seems fine, it is easy to think mosquitoes are choosing randomly. They are not.
Mosquitoes use a combination of cues to find hosts, including carbon dioxide from our breath, body heat, movement and compounds associated with human skin odor. Research from Rockefeller University found that people who were especially attractive to Aedes aegypti mosquitoes had higher levels of certain carboxylic acids on their skin — and that this individual attractiveness stayed remarkably consistent over time.

That does not mean “smelly armpits” are the cause or that deodorant will solve the problem. Human odor is chemically complex, and mosquitoes combine multiple signals before landing and biting.
What Attracts Mosquitoes to a Person?
Carbon Dioxide
Every breath releases carbon dioxide. Mosquitoes use it as one of the cues that a living host is nearby.
Skin Odor
Compounds produced on the skin and modified by skin microbes create an odor profile that can make one person more attractive than another.
Body Heat
Heat helps mosquitoes home in at close range. Exercise and warm skin can add to the cues a mosquito is already following.
Movement and Activity
Activity can increase carbon-dioxide output, heat and perspiration at the same time, potentially making a person easier to find.
What Did the “Mosquito Magnet” Study Actually Find?
The widely shared study did not conclude that people get bitten because they have poor hygiene. Researchers found that highly attractive study participants produced higher levels of carboxylic acids in skin sebum. Those compounds contribute to the odor profile created by human skin and its resident microbes.
The important takeaway is that mosquito attraction appears to be partly biological and persistent. A person can shower, change soap or switch deodorants and still remain more attractive than someone else.
So if you are the person who always gets bitten first, you may not be imagining it.
Different Mosquitoes Hunt at Different Times
Another reason mosquito advice can feel contradictory is that different species behave differently. CDC notes that Culex mosquitoes are generally most active from dusk to dawn, while Aedes species can be aggressive daytime biters.
New Jersey homeowners are especially familiar with the Asian tiger mosquito, Aedes albopictus, a container-breeding mosquito that can live close to homes and bite during daylight hours.
Do Blood Type, Alcohol or Dark Clothing Make You a Mosquito Magnet?
You will see strong claims online about blood type, beer, bananas, perfume and clothing color. Some factors have been studied, but the size and consistency of their effects are not equal to the evidence for core host-seeking cues such as carbon dioxide, odor and heat.
The practical approach is not to build your entire mosquito strategy around a single personal trait. Reduce mosquito habitat, use proven bite-prevention tools and recognize that some people are simply more attractive to mosquitoes than others.
What Actually Helps Prevent Mosquito Bites?
Being a Mosquito Magnet Is Personal. Mosquito Habitat Is a Yard Problem.
You cannot change your basic body chemistry, but you can make the property around you less supportive of mosquitoes. Start with our yard-maintenance guide.

FAQs About Mosquito Attraction
Why do mosquitoes bite me but not the person next to me?
People differ in body odor chemistry, carbon-dioxide output, skin temperature and other cues mosquitoes use to locate hosts. Research supports real, persistent differences in individual attractiveness.
Does deodorant stop mosquitoes from biting?
There is no reliable evidence that ordinary deodorant makes a highly attractive person “invisible” to mosquitoes. Use an EPA-registered repellent when bite protection is needed.
Are all mosquitoes most active at dusk?
No. Many Culex mosquitoes peak from dusk to dawn, but Aedes mosquitoes can bite during the day.
Can I reduce mosquitoes around my home even if I am a mosquito magnet?
Yes. Removing standing water, improving yard conditions and using appropriate professional or public mosquito-control measures can reduce local mosquito pressure.
