Emerald Ash Borer (EAB) is a shiny emerald green beetle about ¾” long. It was imported into the State of Michigan from China in the 1990’s and since that time it has gradually spread. It is now confirmed in 25 states. In August of 2008 the first infestation was found in Wisconsin in the Village of Newburg. In June 2014 the first infestation was found in the City of Hartford.

The Emerald Ash Borer beetle only feeds on ash trees. It lays eggs which hatch in early summer and the larva tunnel into the tree. Larva feed under the bark consuming the cambium and phloem layers causing the tree to die.

Homeowners are responsible to properly maintain trees on their property.

  Without treatment an ash tree that is infested with EAB will die.  The City of Hartford has requirements that homeowners are to remove dead, diseased and hazardous trees. Municipal Code 19.07 c) and 19.10 address the homeowner responsibilities concerning private property trees including maintenance and care.
