Bedbugs beaten once, back again

W e thought we’d beaten bedbugs. After World War II, they had been almost eliminated thanks to the powerful pesticide DDT. But in the past three decades, bedbugs have started to return, resistant to the chemicals that reliably killed almost all of them a half-century ago. For the past nine years, Rose Zhu, an entomology professor at WSU, has been trying to figure out exactly which traits allow bedbugs to shrug off what once killed them. Zhu has known the scourge of bedbug bites. A long time ago, in Washington, D.C., she remembers waking up covered in itchy bites. It wasn’t until she started studying bedbugs that she knew what those bites were from./ Daniel Walters , Inlander. More here .
