PITTSBURGH (AP) — Two teachers and a dozen students were stung by a swarm of bees or wasps during recess at a summer camp program run by the Pittsburgh Public Schools.
The students and teachers were stung Tuesday outside the Carmalt Academy of Science and Technology. About 600 students are attending the district's Summer Dreamers camp.
Some children were stung more than once, school district spokeswoman Ebony Pugh said, but city paramedics said none of the stings prompted allergic reactions or were serious enough to require hospitalization.
According to Steve Repasky, a master beekeeper in Pittsburgh, the culprits were likely yellow jacket wasps.
"I would assume that a kid was probably running around, ran across a nest, and that was enough to trigger a reaction from the yellow jackets," Repasky said.
He pointed out that yellow jackets are commonly mistaken for honeybees, but that bees tend to only swarm in the spring when their colonies get too big and they need to split up. Wasps, on the other hand, are more aggressive.
Maintenance crews are determining whether a hive in the area needs to be removed.
