It’s the height of summer mosquito season, and if you’re thinking the blood-sucking creatures have left you more scabbed, blotched and itchy than your bite-free friends, it’s not just in your head.

Some people are actually more prone to mosquito bites than the average person.

The reason? It’s because of the way you smell. And if you’re drinking alcohol or pregnant, you’re a more likely target for the pesky blood suckers.

Scientists in Britain and the United States who have been studying mosquito-biting patterns say varying levels of chemical compounds found in perspiration are a key factor differentiating the blistered, bitten and itchy and those who seemingly float through every summer bite-free.
