HARRISBURG, Pa. — The Pennsylvania Ag Department has expanded its quarantine zone for the spotted lanternfly to Dauphin County.

The agency announced the move on March 15 after responding to reports of a population of the pest in the county.

The quarantine gives the Ag Department the authority to regulate the movement of commodities that may be moving within or leaving the quarantine zone.

It restricts the movement of articles that contain any life stages of the spotted lanternfly, including egg masses, nymphs, and adults.

All businesses are required to take an online training course designated to help them recognize the lanternfly and prevent its movement, after which they will receive a permit from the Ag Department.

As part of the spotted lanternfly quarantine agreement beginning May 1, 2019, the department's Bureau of Plant Industry will begin to perform inspections and verification checks to confirm that businesses are properly permitted.

Failure to take the permit exam and educate employees could result in possible penalties and fines.

The quarantine zone was last expanded in November 2017 to include Berks, Bucks, Carbon, Chester, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia and Schuylkill counties.

A webinar on the business permit will be held 1-2 p.m. Thursday, March 21. To register, visit
