Scientist have known for some time that mosquitoes sense carbon dioxide in the air. Not only do they sense it they home in on certain chemicals carried in that carbon dioxide. It’s called a carbon dioxide signature.
Plants, animals, water, and almost everything has its own carbon dioxide signature. It is now known that different plants can be identified by this signature. By the same rules even humans all have a different carbon dioxide signature. It’s even being called a carbon dioxide fingerprint and is being used in crime labs to identify people!
Ever wonder why the mosquitoes bite you and not the guy next to you? They are attracted to certain chemicals in the carbon dioxide being released from your body and the guy next to you doesn't have as much of these chemicals in his carbon dioxide as you do. However, there are thousands of chemicals already identified in human carbon dioxide release! What are these certain chemicals that attract mosquitoes? Have they been identified? Yes! but the scientists who discovered them aren't telling us exactly what they are! That’s right they are keeping these facts a secret! All they will say is that three key chemical signatures found in the release of human carbon dioxide will attract mosquitoes at a rate of 100%.
Other scientist have proven that these chemicals are Lactic Acid related and another attractant is fatty acids being released in the human carbon dioxide signature.

They are attracted by scent primarily. A good thing to know as far as survival in the wild is they rarely fly higher then 12' above ground so seeking shelter up in a tree can avoid being eaten alive. Avon has a product called Skin So Soft that has incredible repelling ability for them as well as Sand Flies also known as No-see-ums because of their tiny size. Some people do have a scent that seems to repel Mosquitoes which don't know if I'd consider a compliment but it does have certain benefits as you have seen. Just maybe you should be thankful that you smell sweet enough to draw them in as you do.

It's body chemistry, especially aromatics and skin surface oils. Eating lots of garlic helps repel bugs. Onion may have a similar effect. They are definitely drawn by carbon dioxide; this is well established. If you have a higher resting metabolic rate, you would exhale more carbon dioxide. This can result from exercising more, or from a higher thyroid hormone level. There are probably other reasons.

Mosquitos are attracted to dark clothing such as blue jeans. So if youre wearing blue jeans and your friend is wear red shorts your more likely to get bitten.

probably because only people with hearts have blood and therefore they dont have hearts so what does that tell you?
jk.
perhaps it has to do with anxiety levels because mosquitoes hear heartbeats.
