Why Mosquitoes Bite Some People More Than Others

Mosquitoes are attracted to me and it's likely due to my genes.

References:
Genome Wide Association Study for self-reported mosquito attractiveness:

The twin study showing correlated attractiveness is stronger for identical twins:

Some things we know make mosquitoes more attracted to you:
Exercising, higher metabolism, higher body temperature, more body odor, being pregnant, type O blood, infrequent bathing, lactic acid, ammonia, acetone.

There are a number of folk remedies people believe protect them from mosquito bites like drinking alcohol, eating garlic, or taking vitamin B. These do not appear to provide any benefit in lab studies and in fact drinking alcohol is associated with increased mosquito activity because it causes blood vessels near the surface of the skin to dilate.

And apparently some of your attractiveness to mosquitos is simply genetic. This may be mediated through your immune system, which is what a lot of the genes identified were associated with.

As a professional mosquito I can confirm everything is true

I can’t believe that dude sticks his hand in the enclosure of mosquitoes to let them bite him, that’s just another level of insanity in my opinion.

Very interesting and correct. My wife grew up in Tanzania and she has never had malaria. Mosquitoes hardly bother her. I lived in Tanzania for 12 years and had malaria at least a dozen times or more. Mosquitoes cannot leave me alone

I get bitten so often. Most of the time, anyone who's with me aren't even aware that there's a mosquito around because I'm the only one who's getting bitten. They won't even believe me sometimes ☹

When I saw that room of mosquitoes I was like: BURN IT DOWN.

The ultimate non toxic mosquito repellant is cloves mixed in ordinary cooking oil. Olive or rapeseed oil. Mix the powdered cloves in oil, let stand for a few days, filter the clove powder out, and apply the oil. Tested and proven in Finnish midsummer with a lot of bloodthisrty mosquitoes. One got as close as one inch from my arm when it got the scent and braked and got away.

Whenever you're depressed because nobody seems to like you, remember you're attractive to mosquitoes.

I’ve always hated the fact that mosquitoes bite you not for food, but to MAKE MORE MOSQUITOES

[NaeSeonghwa]

this guy literally sticks his arm in there to feed them mosquitoes just so he can study the dam things..
this is the highest level of dedication ive ever seen

From this video, I learned that you can become an expert in any field you love. I didn't knew that there is a dedicated study for mosquitoes.

I hate mosquitoes with a passion. I can't go outside for 5 minutes without being bitten. As an example, my dad and sister were outside for an hour working on gutter cleaning. Neither were bitten. I stepped outside for 5 minutes (not exaggerating)... 4 or 5 bites. Example two, my brother and I were outside standing in place next to each other for 15 minutes. In that time, I was bitten exactly 9 times and my brother only once.

Mosquitos be like: “It’s your scent. It's like a drug to me. It's like you're my own personal brand of heroin.” -Edward

“They are the most dangerous animal in the world.” He says this as he continues to feed and breed them himself.

My mom and I are completely ignored by mosquitoes and we both have chronic illnesses that mess with our body regulation in various ways, including making us barely sweat at all and have cold skin. We always thought that was why we never get bitten even when my dad and sister are attacked, so the scientist making note to rub your hands together to stimulate warmth/oils on your skin really stood out to me

Is this man a hero or a psychopath?

I have an unhealthy urges to bring my 10.000 watt mosquito racquet to this lab

The thing that really gets me about mosquitos is when you're trying to sleep and they are flying around your ears making that buzzing sound. Anyone else really despise this sound? It's worse than nails on a chalkboard for me as it is usually accompanied by a bite to add insult to injury. You're always just waiting, mortified and annoyed by the occasional

Years ago, I took my family and my brothers family on a camping trip to Fire Island one summer. Out of 8 of us all but my 2nd son Calvin was eaten alive by mosquitos. Calvin had 2 bite marks at the end of the trip while the rest of us was covered in bite marks. We all ate the same food used the same soaps same gene pool. We still talk about how weird that was when we get together in the summer time.
