What are 17-year, or periodical, cicadas?


Periodical cicadas are cicadas that only emerge every 13 or 17 years. This year, the Brood V 17 year cicadas will emerge. These cicadas go into the ground as nymphs and it generally takes 17 years to emerge to complete their final molt to adulthood.

When will they emerge?


Brood V will emerge in late April or in May when the temperature of the soil 8 inches beneath the ground reaches 64 degrees Fahrenheit.

Where will they emerge?


The cicadas will emerge in the following counties in Ohio (some counties will see a heavier emergence others): Ashland, Ashtabula, Athens, Belmont, Carroll, Columbiana, Coshocton, Crawford, Cuyahoga, Fairfield, Franklin, Gallia, Guernsey, Harrison, Hocking, Jackson, Jefferson, Knox, Lake, Lawrence, Licking, Lorain, Mahoning, Medina, Meigs, Muskingum, Noble, Ottawa, Perry, Pickaway, Pike, Portage, Richland, Ross, Scioto, Seneca, Stark, Summit, Trumbull, Tuscarawas, Vinton, Washington, and Wayne.

How many cicadas will emerge?


Tens or hundreds of thousands of cicada nymphs may emerge per acre, depending on location.

Will they be loud?


Yes. The loud, continuous sound you will hear is the song of the male cicada trying to attract females. The females respond with quick wing flicks, but you will mostly be hearing the males.

Are cicadas dangerous?

No. Cicadas cannot sting or bite. The females may pose a threat to young trees or shrubs, so make sure to cover them with wire mesh to prevent them from laying eggs in the trees. Mature trees and shrubs should not be affected. Cicadas are also attracted to power tools that make a sound similar to their song, so they may land on you while you are mowing your lawn.

Cicadas do benefit the soil, trees, plants, and birds. The last time Brood V emerged, the wild turkey population thrived and birds rarely seen in Ohio arrived to eat the cicadas. Also, as the nymphs emerge, the holes they create naturally aerate the soil.

How long do they live?


Once the 17 year cicadas emerge, they only live about six weeks. They take 17 years to mature as nymphs, and then emerge to complete their final molt into adulthood, mate, lay eggs, and die. They will mostly be gone by the fourth of July.

When is the last time they emerged?


The last time the Brood V 17 year cicadas emerged in Ohio was 1999.

When is the next time we will see this brood of cicadas?


These cicadas will emerge again in 2033.
