Honey bee killer found

Einstein is rumored to have said that if honey bees disappeared from Earth, humans wouldn’t last another four years.
For the last couple of years, we’ve been precariously close to testing his hypothesis. Starting in 2006, honey bees would leave to gather pollen and then … poof! they’d never come back to the hive.
Keepers and scientists quickly gave the phenomenon the doomsday name colony collapse order. But even with a catchy-media-friendly name nobody could figure out why the honey bees and hives were dying.
Now beekeepers are sure they have a culprit, one that will not please the American Council of Science and Health because it turns out it was a pesticide.
