Periodical Cicada Brood Emergence Schedule

Cicada Brood Emergence

Periodical cicada emergence occurs almost every year in a 13-year or 17-year cycle. Emergences are identified as “Broods”. 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.

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

Pest netting wrapped completely around the tree or shrub is effective. The mesh needs to be 1/4″ to keep them out.

Cicada Brood Emergence by Year

The cicada brood map below shows what year each brood emerges. A major cicada emergence occurs almost every 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.

Cicada and Locust Protection and Control

Cicada Control Pest Netting

After reviewing the cicada brood map above, you know if and when to prepare for a major brood emergence.

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.
