EAB confirmed in Fridley; treat your trees

Emerald Ash Borer tunnels in an ash tree

The Minnesota Department of Agriculture confirmed an emerald ash borer (EAB) infestation in the City of Fridley on May 7. EABs are an invasive insect pest that quickly kill ash trees by tunneling under the bark and obstructing the flow of nutrients.

Due to the aggressive spread of this pest, all ash trees are considered vulnerable to EAB.

Ash trees on your property

Residents should plan to apply a chemical treatment to protect the tree or remove any ash tree on private property. Trees that are removed should be replaced with a new tree to preserve the benefits of the city’s urban forest. Residents that elect to chemically treat their tree should use a licensed tree care company to inject systemic treatment directly into the tree. 

The city has contracted with Rainbow Treecare to begin its first round of chemical treatment to preserve high quality ash trees in public right-of-ways during summer 2019. As part of the contract, Rainbow Treecare will be extending lower bulk-rate pricing to Fridley residents interested in protecting and treating their ash trees. As part of this service, Rainbow Treecare will offer free site visits to evaluate ash trees.
