Chartiers Valley School District tells KDKA-TV that the students involved in Thursday's prank at the high school in Bridgeville have been identified and will be disciplined. The district spokeswoman, Kara Droney, didn't say what that would entail.
School officials aren't saying how many Chartiers Valley High School seniors were involved, though the television station says it was about six.
School janitors and teachers were enlisted to help round up the bugs. Some of the prank was caught on school surveillance cameras.
