After 17 Years, Billions of Brood X Cicadas Are Set to Emerge from the Ground in the Eastern U.S.

This spring, billions of Brood X cicadas are set to emerge in over a dozen eastern states after living in the ground for 17 years. Cicadas are large, flying insects that are known for their incredibly loud buzzing mating calls. While the thought of billions of insects crawling up out of the ground at once might be nightmare inducing, you have nothing to worry about. The pest pros from Greenix Pest Control are here to answer all of your questions about this rare event.

What Are Periodical Cicadas?

Periodical cicadas are cicadas that spend most of their lives underground only to emerge once every 13 or 17 years. There are 7 different species of periodical cicadas and they are all found in eastern and midwestern North America.

What Are the Brood X Cicadas?

Also known as the Great Eastern Brood, Brood X cicadas are a group of periodical cicadas that emerge every 17 years. There are 15 different broods and each is categorized by geographic location and the year it is set to emerge. Of any of the other 17-year cicada broods, Brood X has the greatest geographical range and concentration.

What Can I Expect When the Brood X Cicadas Come Out?

Once they emerge from the ground, nymph Brood X cicadas will shed their skins, thus becoming adults. Then, they will make their arrival known by making loud buzzing and clicking sounds (mating calls). They will spend the next four to six weeks flying, mating, and laying their eggs before their life cycle comes to an end.

Once the adult cicadas die off, their eggs will hatch and the young will burrow into the ground for the next 17 years before reemerging.

The Brood X cicadas will emerge in woods and neighborhoods in the following states:

  • Delaware
  • Illinois
  • Georgia
  • Indiana
  • New York
  • Kentucky
  • Maryland
  • North Carolina
  • New Jersey
  • Ohio
  • Pennsylvania
  • Tennessee
  • Virginia
  • West Virginia
  • Michigan
  • Washington D.C.

Are Brood X Cicadas Dangerous?

No. Other than giving you the heebie-jeebies, Brood X cicadas do not pose any real threat to you. These insects don’t bite or sting and prefer to stay outdoors, so you don’t have to worry about them coming into your home.
