Mosquitoes are actually the most dangerous animals in the world, killing more than two million people per year. They are crepuscular, most active at dawn and dusk. A mosquito does not "bite", but siphon the blood out by a tube. The blood serves no nourishment. Mosquitoes require protein so that their eggs can mature prior to laying, which is why only the females drink blood. Males eat plant sap and nectar.

Despite the fact that humans have all this other warm body parts that mosquitos could be biting and busy with, it always seems like all they want is to buzz in your ears. They are actually not attracted to your ears. What we know is that they are attracted to exhales and body heat. To find victims, the female mosquito follows cues like your body heat, moisture and carbon dioxide emissions. In particular, the carbon dioxide you give off when you exhale attracts the insect to your heads, where they fly around looking for a landing spot.

Mosquitoes also have eyes that can see shades of black and white, as well as movement. Still sensors allow the insects to locate the heat. When a mosquito gets a sniff of carbon dioxide, the smelling part of its brain begins to send messages to the visual part telling it to be on the lookout for food. The ears just happen to be the place where you hear them the most as they are attracted to any exposed part of your body while you sleep. In other words, mosquitos are so busy flying around your body while you sleep they are bound to pass by your ears to the point that you will think they are just buzzing in your ears to annoy you all night long. You can scare them off by eating garlic!

The only place mosquitoes do not live is Antarctica.
