SUMMERVILLE, S.C. -- There’s been some collateral damage in the fight against Zika -- millions of honeybees in South Carolina.

News outlets report that Dorchester County officials have apologized for killing the bees when the county failed to notify local beekeepers about mosquito spraying last weekend.

Four travel-related cases of the Zika virus have been confirmed in the county northwest of Charleston. Aerial mosquito spraying operations were conducted Sunday morning.

Flowertown Bee Farm and Supply in Summerville lost more than two million bees.

Company co-owner Juanita Stanley said the farm “looks like it’s been nuked.” Andrew Macke, a hobby beekeeper, said he lost thousands of bees.

The county usually notifies beekeepers before it sprays for mosquitoes. Officials say Sunday was the first time spraying had been done from the air.
