On Sunday morning, the South Carolina honey bees began to die in massive numbers.
Death came suddenly to Dorchester County, S.C. Stressed insects tried to flee their nests, only to surrender in little clumps at hive entrances. The dead worker bees littering the farms suggested that colony collapse disorder was not the culprit — in that odd phenomenon, workers vanish as though raptured, leaving a living queen and young bees behind.
Instead, the dead heaps signaled the killer was less mysterious, but no less devastating. The pattern matched acute pesticide poisoning. By one estimate, at a single apiary — Flowertown Bee Farm and Supply, in Summerville — 46 hives died on the spot, totaling about 2.5 million bees.
Walking through the farm, one Summerville woman wrote on Facebook, was “like visiting a cemetery, pure sadness.”
...the insect neurotoxin cannot discriminate between honey bees and bloodsuckers. A profile of the chemical in Cornell University’s pesticide database warned that “Naled is highly toxic to bees.”
Although the insecticide was known to kill bees, to South Carolina beekeepers spraying had not been as significant a concern as parasites, disease and other hive threats. As South Carolina Beekeepers Association President Larry Haigh told the Post and Courier in June 2015, many counties will spray at night, when honey bees do not forage for pollen. Plus, given sufficient warning, beekeepers will shield their hives and protect the bees’ food and water from contamination.
Sunday was different. Summerville resident Andrew Macke, who keeps bees as a hobby, wrote on Facebook that the hot weather left bees particularly exposed. Once temperatures exceed 90 degrees, bees may exit the nest to cool down in what is called a beard, clustering on the outside of the hive in a ball. Neither Macke nor Stanley had covered their hives.
And then came the plane.
“They passed right over the trees three times,” Stanley said to ABC 4 News. After the plane left, the familiar buzzing stopped. The silence in its wake was like a morgue, she said.
As for the dead bees, as Stanley told the AP, her farm “looks like it’s been nuked.”
