The Emerald Ash Borer (EAB) is a species of green beetle that is native to Asia. It is invasive in North America. The presence of EAB was first discovered in the United States (Michigan) in 2002. Since that time, EAB has been responsible for the destruction of millions of ash trees as it spreads throughout the country.

 2002   Upon learning of the EAB problem, the Parks Division stopped planting ash trees.
 2012

In June, the City of Janesville first discovered the presence of EAB within the corporate limits of the City of Janesville.

Throughout the remainder of 2012, staff consulted the Wisconsin Department of Natural Resources and the public to develop a strategy for managing the EAB problem.

Pre-emptive tree removal on public land was completed between 2012-2013.
 2013 The Parks Division treated 205 ash trees and installed EAB traps in ash trees around the City to determine the scope of the problem.
 2014 106 trees planted on public property as part of a WDNR Urban Forestry Grant.
 2015 Continued tree planting, treatment of ash, and ash removal

Important Points to Remember

  • There is no solution to stopping the spread of EAB and no way in which to eradicate it.
  • All Janesville residents are asked NOT to transport firewood from Janesville to other locations.
  • Citizens concerned with the condition of an ash tree on their property are encouraged to contact a tree service company they are familiar with or an ISA certified arborist. A listing of certified arborists may be found on the Wisconsin Arborist Association website: http://www.waa-isa.org
  • Residents are cautioned that there may be companies traveling to the Janesville area that may be looking to scam ash tree owners or inflate prices for tree services. Residents should review the State EAB website to understand the options available for ash tree owners before contracting with any tree service company or arborist.
  • Live and even infected ash trees with up to 30% infestation can still be treated and protected. You as a property owner can chemically treat your own ash trees. Further information is available on the EAB Insecticide Information section of the Emerald Ash Borer Information website.
