In 2002, an invasive insect species that you may have heard of—a tiny green beetle known as the Emerald Ash Borer—was discovered by Michigan foresters.
The EAB, as it’s commonly known, was decimating trees in southeastern Michigan and in nearby Windsor, Ontario. This pest had most likely hitched a ride on a shipping boat, and stowed away in ash pallets and crating.
Over the past decade, the EAB has destroyed between 50 and 60 million Ash trees in a destructive path starting in Michigan and cutting through to Pennsylvania. All major Ash tree species have been attacked by the EAB, and unless proper treatment is given immediately, trees will continue to suffer in Bucks and Montgomery counties.
Ash trees make up nearly 20 percent of our local tree population. This is a potentially devastating problem. So how do you know if the Ash trees on your property are being affected?

How to Protect Your Trees from the Threat of the Emerald Ash Borer
The Emerald Ash Borer (EAB) is a classic example of how invasive species thrive. This tiny green beetle is native to Asia and wasn’t seen in the United States until 2002, when it was discovered by Michigan foresters.
Research indicates that the beetle was mistakenly introduced to the country via shipping materials. Since then, the flying green beetles have spread east, including into the state of Pennsylvania. Its presence was documented in Warrington, PA in the spring of 2012, and it has since spread throughout the Bucks County and Montgomery County areas.
At this point, it is believed that these insects are now in our local wood products, such as mulch and wood chips, and are expected to continue to spread rapidly. The Emerald Ash Borer feed on Ash trees, where they lay their eggs in bark crevices. And unfortunately, if something isn’t done about these destructive pests soon, there won’t be any Ash trees left.
EAB has already been responsible for the loss of millions of Ash trees in North America, and at the current rate, there’s every reason to imagine that the Emerald Ash Borer could cause the Ash tree to become an extinct species.
If you have Ash trees on your property, it’s time to meet with a certified arborist to discuss your options.
