911 Calls About Ear-Splitting Cicada Eruption Are Bugging Authorities Stop it! As millions of “chirping” cicadas emerged this summer, authorities in one Georgia county issued a desperate plea: Don’t call 911 about the insects! Yes, there are a ton of the “Brood X” emergents, and yes, they make a piercing sound that can sound like an alarm. They’re the loudest insects on the planet and the males meld their calls to create an overwhelming, amplified chorus that captures the attention of females. But please don’t dial 911 to alert authorities about them. “Union County E911 is receiving multiple 911 calls for ‘alarms’ in the neighborhood. More than likely these ‘alarms’ are not alarms at all but a bug, Brood X,” the Union County Fire/Rescue noted on Facebook. “If you think you hear an alarm, ensure that it is an alarm and determine the location before contacting authorities.”
