It was only a matter of time. Lately newspapers have been filled with stories about the return of bed bugs, those nocturnal bloodsuckers that most of us had previously encountered only in our parents' nightly admonition to not let them bite. I grew up thinking that they weren't even real, just something adults made up along the lines of the bogeyman, monsters, and the tooth fairy. But they are indeed real, and they were once common in the U.S., until — as nearly every contemporary article about their resurgence points out — they were eliminated by the use of DDT just after WWII. So it was only a matter of time before people started blaming the current resurgence of bed bugs on EPA's ban on DDT.
