Blood type, body temperature and skin bacteria influence the mosquitoes' behavior

I've often wondered why it is that mosquitoes rarely come anywhere near my friends, yet for some reason seem unable to get enough of my blood.

Apparently, there is one very simple explanation: these insects play favorites, and choose their next victim according to a set of very precise criteria.

Researchers say that, first off, mosquitoes have a particularly sweet tooth for Type O blood. Thus, they like it twice as much as they do Type A. Types B and AB fall somewhere in the middle.

Mosquitoes are also attracted to carbon dioxide, so bulky people who exhale more of this gas have higher chances to be bitten.

Sources say that these pests display a noteworthy preference for the scent of sweat and high body temperatures, so those who enjoy jogging in the great outdoors should expect to return home with one too many itchy spots on their skin.

Skin bacteria have been documented to attract mosquitoes, as long as the bacteria colonies that have set up camp on our bodies are not very diverse.

Apparently, people who have lots of bacteria types thriving on their skin are a no-go for mosquitoes.

Oddly enough, mosquitoes appear to like the scent of beer. Scientists don't yet know why, but the fact remains that people who drink beer on a regular basis are more likely to be bitten.

Lastly, people who wear colors that stand out (i.e. red, dark blue and black) have higher odds of being bitten.

This is because mosquitoes use their sense of sight when out looking for their next victim, so, naturally, those who don't blend in with their surroundings don't take long to get their attention.
