About one person in five is especially attractive to the annoying insects. This is how your skin seduces them.

About 1 out of every 5 people is a target. Mosquitoes want your blood, but not for the reason you might think. Male mosquitoes actually aren't interested in your vital fluids at all, but females are very interested. They need human blood to develop fertile eggs.

It turns out it's all about what's on your skin. And they can hone in on you from about 50 yards away.

Scientists are still trying to unpack it all but there’s a few things they know make you a target. One of them is bacteria. About a trillion microbes live on your skin and create your body odour. But most people only have 10% of their microbes in common, which means we’re not all the same. So some of us have a collection of microbes that are particularly tasty for mosquitoes.

Then, there’s CO2. Mosquitoes love carbon dioxyde, so the more a person emits, the more attractive they are. Larger people give up more CO2 than smaller people, which is why mosquitoes bite adults more than kids, and the bigger the adult, the juicier the target.

Mosquitoes are also drawn to movement and heat, so if you’re out in the park playing soccer, mosquitoes can sense your movement and increased temperature and zip towards you. And if you’ve run around so much that you’re out of breath, it’s like the perfect storm. To a mosquito, you’re like a juicy steak waiting for its plate.

So defend yourself. There are only two proven things that work:
- Insect repelent with DEET
- and OTC (over the counter) antihistamines
