But you may have noticed mosquitoes bite some people more than others.

Scientists have figured out that it’s not because “Your blood is sweet”.

It has more to do with the smell of your skin.

Everyone’s skin is covered in different combinations of bacteria.

And those bacteria all produce different chemicals.

The smells created by some combinations of those chemicals make certain unlucky people irresistible to mosquitoes.

Research also suggests mosquitoes are attracted to people exercising.

The increased body temperature acts like a dinner bell.

They’re also drawn in by:

  • The carbon dioxide we exhale
  • Lactic acid
  • And they seem to be attracted to beer drinkers

So if you think that mosquitoes bother you in particular – YOU MIGHT BE RIGHT!

Make sure to use good repellent.

Only insect repellents with DEET or Permethrin will keep you off the menu.

Be sure to use if you are traveling to a place with mosquito-borne disease.”
