Wisconsin Tree Insect Control- Emerald Ash Borer Treatment

Emerald Ash Borer in Wisconsin

HOW CAN SUCH A SMALL AND COLORFUL BEETLE CAUSE SUCH DEVASTATION?

Emerald Ash Borer

  • Over 14 million ash trees already killed in Michigan, Indiana and Ohio.
  • Emerald ash borer has been found in Wisconsin too.

The invasive and destructive Emerald Ash Borer was first discovered in Wisconsin August 2008. This invasive insect native to China has no natural predators in the United States and has spread across a multitude of states, killing millions of ash trees. Despite regulations on transportation of firewood and current methods to eliminating the insect, the Emerald Ash Borer has been found for the first time in Racine County late July 2011.

The metallic green beetle known for its destructive nature was found in three separate traps in northern Racine County. Department of Agriculture experts say this is unfortunate news, although not surprising. One of the traps is located one mile north of Oak Creek, a Milwaukee suburb infested with the ash tree killing insects. Emerald Ash Borers have been discovered in eight Wisconsin counties including Milwaukee, Racine, Kenosha, Brown, Crawford, Vernon, Ozaukee, and Washington.

Wisconsin has taken further steps towards eliminating the Emerald Ash Borer by implementing biological methods to weaken the Emerald Ash Borer population in Wisconsin.
