Periodical Cicada Brood Emergence Schedule

Where Will a Cicada Brood Emerge This Year?

Periodical cicada emergence occurs almost every year in a 13-year or 17-year cycle. Emergences are identified as “Broods”. When a brood emerges, the insects come out of the soil by the millions, if not billions. The Cicada brood map table below identifies when they emerge, and the states that are affected. When a cicada brood emerges, it may impact all or just part of the state. Find out where will a cicada brood emerge.

For heavy emergences, you should take steps to protect trees and shrubs that are susceptible to damage. See a list of susceptible plants below.

Cicada pest control netting netting wrapped completely around a tree or shrub is effective. The mesh needs to be 1/4″ to keep them out. They get through larger mesh sizes. It is also important to tie off the bottom so the insects cannot get into the tree or shrub.

Cicada Brood Emergence by Year- Where Will Cicada Brood Emerge?

The cicada brood map below shows what year each brood emerges. A major cicada emergence occurs almost every year. This chart defines where a cicada brood emerge this year. If your state is listed, the emergence will occur in some or all parts of the state.

Early and Late Brood Emergence: On occasion, an emergence comes earlier or later than expected in some areas. When an emergence is off by a year or more, it is called “Straggling”. In 17 year cycles, emergences four years early have been documented.

When Will a Cicada Brood Emerge?

Different broods come out in varying parts of the country, mostly east of the Mississippi river. After lying dormant underground for 13 or 17 years (depending upon brood), Cicadas emerge from the soil in the spring after the soil has warmed up. By this time the leaves have developed on trees and shrubs. Then as the soil temperature reaches 64° F, the insects dig tunnels up through the soil. They will come out of the soil over several days. This usually occurs in mid to late May. About six weeks elapse from the time of the first sighting in your area, until the end of their short adult life cycle. Then, they will spend the next 13 or 17 years out of sight underground.

Cicada and Locust Protection and Control

After reviewing the cicada brood map above, you know if and when to prepare for a major brood emergence. Do not wait until they have come out of the soil. If a brood is expected to emerge in your area, protect your trees and shrubs before they emerge.

Insecticides are ineffective on these large insects.

Insect Netting is the most effective way to protect young trees and shrubs, which are most susceptible. Because Cicadas are large insects, 1/4″ mesh netting is effective. Wrap pest netting completely around the tree and tie or seal it off, to keep any insects from finding an entryway.

Important Note: Even if the Cicadas have emerged in your area, you have 5-10 days to cover young trees before the female begins to cause damage, as she lays her eggs.
