HARRISBURG, PA - Emerald Ash Borer beetle has been discovered in Bucks, Franklin, Jefferson, Perry, Snyder and Venango counties. With these new finds, 28 counties are now dealing with the invasive ash tree-killing pest.

A federal Emerald Ash Borer quarantine restricts moving ash nursery stock, green lumber, and any other ash material, including logs, stumps, roots and branches, from the state, though the U.S. Department of Agriculture may allow some movement of wood products within the 16 infected states. 

"Emerald Ash Borer beetles have plagued Pennsylvania since 2007 with new positive sites found each year," said state agriculture secretary George Greig 

USDA is assisting the state in blocking the spread of the ash borer, whose most recent advance was found as part of a national survey using triangular purple traps from hung in ash trees in eastern Pennsylvania beginning in May.

Ash borers and pine beetles have also been spreading in forests in Canada.
