Flying insects will descend on cities, towns and villages from New England to North Carolina as part of a natural phenomenon that only occurs once every 17 years.
And there will be no escaping their noise — which has previously been compared to the sound of a New York City subway train.
But there's no need to worry, as experts say they are harmless to humans and trees.
Craig Gibbs, entomologist at the Wildlife Conservation Society's Queens Zoo, told CBS News that the Brood II was a "periodic cicada that hatches out every 17 years."
"The nymphs will come up, shed their nymphal skin and crawl up into the trees. They'll take about five days to harden and then start for four to six weeks calling and looking for mates," Gibbs added.
Dan Mozgai, a New Jersey resident who started cicadamania.com, told the Journal News he was expecting "significant emergence in New Jersey north of the Raritan River, in Staten Island, and in counties along the Hudson River."
The cicadas will then disappear, after a month of breeding, until 2030.
