Fayetteville officials warn of invasive Emerald Ash Borer beetle

The Emerald Ash Borer is spreading in Arkansas, threatening to harm ash trees in Fayetteville.

FAYETTEVILLE, Ark. — The Emerald Ash Borer, a pest known for its destructive impact on Ash trees, is spreading in Arkansas, prompting warnings from Fayetteville officials about a looming infestation. 

Washington and Benton counties have reported confirmed cases of the invasive species.

The Emerald Ash Borer, which arrived in North America by accident in 2002, has thrived, causing widespread damage. 

John Scott, an expert on the species, said it specifically targets ash trees, attacking them internally and cutting off their ability to exchange nutrients and water. 

“In essence, it’s going to kill all of our Ash trees if we don’t do anything about it,” Scott said. 

Although Ash trees account for less than 2% of Fayetteville’s shade, experts emphasize their importance in maintaining a healthy habitat. 

The beetle’s life cycle begins with eggs hatching inside the tree trunk, where larvae feed on the inner bark, leaving behind distinct D-shaped holes and dead trees. To prevent further spread, the city advises against moving firewood. Keeping wood local is crucial, as transporting it can inadvertently spread the beetle. 

Residents in Fayetteville facing an infestation must decide whether to treat or remove affected trees. Treatment options include trunk injections, soil drenching, and bark spraying, each requiring ongoing maintenance. 

Scott noted that these methods can protect trees but must be repeated regularly, with trunk injections lasting up to two years and other treatments needing yearly applications. 

Fringe trees, a small ornamental species, are also susceptible to the emerald ash borer. However, their size allows residents to manage treatment themselves.
