The Aedes aegypti mosquito is a beautiful, brilliant killer. Dark with white spots and a wingspan of only a few millimeters, it is smaller and stealthier than the mosquitoes that might keep you up at night, buzzing in your ear. There are thousands of species of mosquitoes, but only a few hundred are interested in humans. The Aedes aegypti is among the deadliest of them all. The Aedes lives and breeds in places where people are, laying its eggs in a few droplets of stagnant water at the bottom of a forgotten beer can and then spending its short life hiding under beds and in closets.
