Volunteers launched an operation to clear wasp nests around a school in Phimai district of this northeastern province after students were stung.
Workers from Hook 31, a charitable foundation in the area, arrived at Nikom Sang Ton-eng 3 School in Phimai with equipment -- gas cylinders and pipes -- yesterday morning.
The school administration contacted the foundation after many schoolchildren complained of being stung by wasps while they were in class and playing on the football field.
Rescuers found there were more than 50 wasp nests in the bushes around the school as well as on windows, door frames and awnings around the school building.
They destroyed the nests with flames from gas cylinders.
