Emerald Ash Borer (EAB) is a non-native beetle that attacks and kills ash trees. The first confirmed case of EAB in Minnesota was found in St. Paul in 2009, and it has since spread throughout Ramsey and Hennepin counties. EAB was confirmed in southeast Minnetonka in May 2019.
EAB is primarily spread by transporting ash firewood or pruning and removing ash trees while the beetles are active (May 1 through Sept. 30).
It is imperative that Minnetonka residents and businesses prepare for the effects of EAB infestation. Ash trees killed off by EAB are extremely brittle, pose a risk to property and roads, and are dangerous and costly to remove.
The city began preparing for EAB in 2010 and will continue to implement its ash management program. This includes:
- Removing ash in the right-of-way along city streets (at no cost to property owners)
- Reducing the number of poor-quality ash on city property
- Injecting large, healthy ash on city property in an effort to protect them from EAB
Educating residents about the risks of EAB and options for controlling its spread

EAB Management for Businesses
Our forestry staff would like to help Minnetonka's businesses develop an EAB management plan. Here’s how to start, and what we can provide.
- Contact Diana Preisen via email or phone (952-988-8441) to request a free site visit where we’ll:
- Count the ash trees on your property and, by request, mark each with a green dot at the base
- Determine what percentage of your trees are ash species
- Make recommendations to treat or remove ash trees
- Recommend other species to plant
Due to coronavirus and our social distancing efforts, we’ll limit our in-person contact to your trees only. We can share our findings and suggestions via phone or email.
