These Are the Signs Cicadas Are About to Invade Your Yard, Expert Warns – Best Life

For years, entomologists have been anticipating the return of the Brood X cicadas that return every 17 years. Summer 2021 will finally mark the emergence of trillions of these crunchy-shelled creatures in 15 U.S. states. If you're wondering whether you'll be affected, experts say that there are some tell-tale signs that the Brood X cicadas might be on the brink of emerging right in your own backyard. Read on to find out how to know if cicadas are about to invade your yard, and for more on their imminent return, If You Live Here, Prepare for a Major Bug Infestation, Expert Warns.

The Brood X cicadas live underground for the 17 years they lie in wait, but eventually they have to bust through the ground to make their great escape, which could result in holes in your yard. "We're seeing holesholes all over the place. Those are holes made by the cicadas," cicada expert Gene Kritsky, PhD, dean of Behavioral and Natural Sciences at Mount St. Joseph University, told NBC affiliate WLWT5. Kritsky said the finger-sized holes are up to an inch long and can easily disappear after rain. CNN noted that these holes are commonly found at the base of trees.

According to the University of Maryland, some nymph cicadas construct mud chimneys over the emergence hole. These mounds of mud may be two to three inches high and one to two inches wide, with a hole that's about half an inch wide in the center. Cicada Mania notes that cicadas tend to build these chimneys in wetter, muddier areasotherwise, they simply make the holes. The chimneys help keep water and mud from sliding into the holes, so the cicadas can continue to breathe, pop up to check the surroundings, and prepare to emerge.

Kritsky said he's received at least half a dozen reports over the past few days that people are seeing mud chimneys in the Cincinnati area. "Those were made during the rain we had last week. During a nice constant rain, some cicadas will actually extend their tunnel above ground," he explained.

If you're heading outside to start prepping your yard for summer, keep an eye out for cicadas lingering just below the surface. Kritsky said he recently received reports from people who dug up cicadas while gardening or doing other yard work. "If you went out and dug up cicadas today, what you would find is that the nymphs have red eyeswhich means they're coming out this yearbut they have not yet developed these characteristic black pouches behind their head," Kritsky said. "They're not ready to emerge just yet." And for more useful information delivered straight to your inbox, sign up for our daily newsletter.

Jessica Ware, PhD, an associate curator of invertebrate zoology at the American Museum of Natural History, told Reuters she expects the Brood X emergence will be sometime around May 13. Kritsky agreed that the cicadas would likely emerge during the first half of May, but noted that they'll likely peak in late May and June. "We had a lot of people very excited last week when we hit the 80s, thinking, 'Maybe they'll come out a month earlier.' But they're physiologically not ready to emerge," he said.

A warm rain will likely trigger their emergence. These cicadas' lifespan is about four to six weeks above ground before they begin to die off. However, since they don't all emerge at once, you shouldn't expect them to all be gone within six weeksthere will be some lingering late bloomers.
