How do mosquitoes find water to reproduce?

I live near the Mediterranean, in a region where it doesn't rain 4 months a year, and we still get plenty of mosquitoes every summer. There is practically zero fresh water in the area, still or running. This leads me to think that mosquitoes aren't just flying around looking for water to lay their eggs through sheer luck. They must have a way of detecting those places where water is present.

Mosquitoes like many insects have incredibly sensitive sense organs in the form of antennae. These are able to detect a whole range of molecules including water. It's similar to us being able to smell but way way more sensitive. 

Many mosquito species (such as aedes aegypti) will lay eggs in containers just above the water line, so when it rains these eggs get wet and hatch. Other species will lay eggs in mud and only after a number of rewettings will they hatch.  This is why you get a massive increase in the population very quickly.
