Emerald Ash Borer History

The Emerald Ash Borer was first seen in Detroit in 2002, and it has been steadily migrating south. Experts believe that the Borer probably found their way to the United States on wood packing material transported in airplanes or cargo ships arriving from Asia.

The Borer was first noticed in the region when about 20 percent of the ash trees in the area had died. The estimate has now climbed to 80 percent. Borers can kill an ash tree in two to three years and is not easily recognized because an infected tree can look very healthy until too much damage has been done to the tree.

The State of Ohio conducted a study in 2006 published as The Potential Economic Impacts of Emerald Ash Borer. This study reported that the average Ash tree was 12.4” in diameter. The removal and replacement of this tree would on average cost $1,772 to the homeowner. Sadly, there really isn’t a replacement for this tree and Cincinnati ash borer treatment is becoming increasingly more common.
