Overview

The emerald ash borer (EAB) is a non-native insect of major concern that was discovered in Saint Paul in May, 2009. In recent years Michigan and other states have suffered widespread ash deaths numbering in the millions due to this insect. The Saint Paul Forestry Unit is working collaboratively with local, state and federal agencies on efforts to mitigate the effects of this destructive pest.

The purpose of this guide is to inform Saint Paul residents of the various strategies available for ash tree management in response to emerald ash borer. Infested ash trees left to die will over time become very brittle and pose a threat to the safety of the public. Homeowners should become familiar with management alternatives for ash and prepare for action.

Considerations for ash treatment: The City of Saint Paul employs insecticide as just one tool to assist in slowing the spread of EAB and as a means of response to a more manageable time and expense. Treatment of boulevard trees is not employed as a means of saving trees for the long term. Soil drench and soil injection administered insecticides may be toxic to beneficial invertebrates, mammals, and fish. Soil drenches and injections also have the potential to leach into surface water and ground water. Trunk injected insecticides have fewer concerns for water quality. Refer to: Emerald Ash Borer: Homeowners Guide to Insecticide Selection, Use, and Environmental Protection for help in selecting a treatment option. Compare the cost of treatment versus removal and replacement of tree with the Perdue University Emerald Ash Borer Cost Calculator Tree care companies Boulevard trees may be treated at the expense of the homeowner with approval from the Forestry Unit and a free permit.
