Emerald Ash Borer

EABEmerald Ash Borer (EAB) is a devastating insect that attacks all species of the Ash family. It is an invasive wood boring beetle whose larvae create tunnels under the bark of the tree, which cuts off the nutrient and water supply. This causes canopy dieback and eventually tree mortality. EAB has been detected in Dakota County. The City of Farmington has developed an inventory of trees on public property. It is estimated that 44% of city boulevard trees are ash trees.

Farmington's Discounted EAB Treatment Program

Farmington has contracted with Rainbow Treecare, a professional tree care service, to provide EAB treatment for ash trees on public property. Reduced pricing is available to Farmington residents for treatment of ash trees on private property. To take advantage of this discount EAB treatment program, visit the customer portal or call 952-767-6920 (mention the Farmington program). The contracted prices are valid through the end of the 2023 season. Ash tree injection treatments are recommended to be scheduled between June 1 and Sept. 30 (before fall leaf color change - usually around Sept. 30), when EAB larvae are most active. As a property owner, it is important to identify if you have ash trees on your property.

If you have ash trees – prevention is the most effective way to combat EAB. Here's what to expect from Rainbow Treecare:

    1. Schedule an onsite visit and assessment with a certified arborist from Rainbow Treecare to evaluate the property’s ash trees.
    2. A proposal will be created based on the arborist’s assessment that is sent to the property owner for review and acceptance.
    3. EAB treatment is performed after the proposal is accepted. Scheduling is done by Rainbow Treecare’s Customer Care Team and a licensed crew arrives to treat the trees. Rainbow Treecare will keep a record of the property’s treatment history for you.

Residents will be responsible for the full cost of these treatments. Money back guarantee – if your tree dies from Emerald Ash Borer while under treatment by Rainbow Treecare, they will refund your treatment costs.
