MIAMI — Life in Florida was unbearable before the widespread adoption of two life-changing pieces of technology: air conditioning and mosquito control.

And while screen doors and a healthy (or, in hindsight, not-so-healthy) dose of DDT might have done the trick in the 1950s, nowadays, the war on skeeters has entered a new front. Here, the ...Read more
