Brood XIV cicadas—a fascinating 17-year periodical brood—are preparing for their grand appearance in New Jersey during spring 2025. This remarkable natural event is part of a larger emergence spanning at least 13 eastern states, bringing these unique insects back into our communities after nearly two decades underground.
The emergence is expected to begin in mid-May 2025, when soil temperatures about 8 inches below the surface reach approximately 64°F. Cicadas will continue to emerge through late June, with the most activity typically occurring in late May.
In New Jersey, you can expect to see these insects primarily in Atlantic County (notably around Linwood), Camden County (Pine Hill area), and Ocean County (Lakehurst area). Residents of Burlington, Cape May, Mercer, and Monmouth counties may also witness lighter emergences.
When cicadas emerge, prepare for quite a concert! The chorus of millions of cicadas can reach sound levels up to 100 decibels—similar to a lawnmower or passing jet. This above-ground phase lasts several weeks, during which cicadas mate and lay eggs before dying. Their offspring then burrow underground to begin the next 17-year cycle.
For seniors who may have witnessed previous cicada emergences, this event offers a chance to share memories with younger generations. While noisy, cicadas are completely harmless to humans and pets. They don’t bite or sting, and they actually benefit our ecosystem by aerating soil, providing food for wildlife, and naturally pruning trees when they lay their eggs.
The highest concentrations of cicadas are expected in Atlantic, Camden, and Ocean counties, with possible lighter emergences in surrounding areas. If you live in or plan to visit these regions between May and June 2025, you’ll have front-row seats to this remarkable natural phenomenon.
For those with gardens or young trees, consider delaying new plantings until July, or protecting small trees with netting. Hearing aids can be adjusted during peak emergence periods if the noise becomes bothersome.
This cicada emergence represents a special opportunity to witness one of nature’s most fascinating timing systems—a living reminder that some of earth’s most extraordinary events operate on schedules much longer than our own daily routines.
