Emerald Ash Borer

Forestry staff has begun surveying private properties for EAB. Surveys will occur through the month of January.

We are looking for trees that are mildly to heavily infested with EAB to help slow the spread throughout the City. We are doing initial surveys from our vehicles, which will have a City logo on the side. If we find any residential trees that are heavily infested, we will send a letter to the property owner asking for permission to access the property, at which time property owners can make an appointment with us so we can inspect the tree up close. No trees will be marked for removal until we have been allowed to inspect the tree.


Emerald ash borer (EAB) is a non-native invasive insect that kills ash trees. Minnesota is home to approximately 900 million ash trees, the most of any state, making it very susceptible to the destruction caused by EAB. Trees become infested when adult beetles lay eggs on the bark. The eggs hatch into larvae that bore into the tree, eventually killing it.

EAB in Lakeville

EAB was discovered in Minnesota in 2009 in the City of St. Paul. Infestations of EAB were found at Lebanon Hills campground in Eagan in 2014 and near Cedar Avenue and County Road 42 in Apple Valley in 2016. EAB was detected in Lakeville in October 2017, and the City is currently managing this insect. 

Curious about where EAB has already been found in Lakeville? The Minnesota Department of Agriculture (MDA) hosts an interactive map that tracks where EAB has been found throughout the state. This map does not show a “tree-for-tree” designation, but a pin dropped in a neighborhood where EAB has been confirmed.
