The wasp attacks began shortly after the fireworks show started at 9:15 p.m. About 5,000 people were in the grandstands, and 15 minutes later sting victims started showing up in the first aid area, Knowles said.
"Apparently there were a number of (yellow jackets) also in attendance for the fireworks display last night," Knowles said Saturday.
She said emergency personnel at the fair set up a triage area to care for those who were stung. Everyone was treated on site and there were no hospitalizations, Knowles said.
By midnight Friday, an exterminator located and removed a ground nest, Mitchell said. The yellow jackets were probably disturbed by the vibrations as the fireworks were launched, not the explosions overhead, she said.
None of the victims were allergic to the stings. Link
