Emerald Ash Borer beetles found in Westmoreland County, Pa.


HARRISBURG, Pa. — Emerald Ash Borer beetles have been found in Allegheny Township, Westmoreland County, bringing to seven the number of counties where the ash tree-destroying pest has been identified, Agriculture Secretary Dennis Wolff said.

The invasive beetle was first detected in Pennsylvania in the summer of 2007 in Butler County, and subsequently was found in Allegheny, Beaver, Lawrence, Mercer and Mifflin counties.


To help slow the spread of the beetle, the state-imposed quarantine for those six counties is being expanded to include Westmoreland County.

State and federal Emerald Ash Borer quarantines restrict the movement from the quarantine area of ash nursery stock, green lumber and any other ash material, including logs, stumps, roots and branches, and all wood chips.


This summer, 20 crews — 15 in western Pennsylvania, one in Mifflin County and four in the eastern part of the state — and two regional coordinators have been deployed to assess the spread of the beetle.

The Westmoreland County crew detected the new infestation.

“Our survey crews are assessing the extent of the infestation in Westmoreland County and surrounding areas,” said Wolff. “We remind consumers to heed the quarantine when traveling and camping this spring and summer — not just in the quarantined areas but throughout Pennsylvania — to prevent any further spread of the beetle.”

Due to the difficulty in distinguishing between species of hardwood firewood, all hardwood firewood — including ash, oak, maple and hickory — are considered quarantined.

Do not transport wood

Since many species of wood-boring insects, including the Emerald Ash Borer, can be spread by transporting infested firewood and logs, campers and homeowners are encouraged to use only locally harvested firewood, burn all of the firewood on-site and not carry it to new locations.

There is no known practical control for this wood-boring pest other than destroying infested trees.

People who suspect they have seen Emerald Ash Borer should call the department’s hotline at 866-253-7189.
