Emerald Ash Borer




In April of 2019, the MN Department of Agriculture confirmed that Emerald Ash Borer (EAB) was officially in North St. Paul. Fortunately, the City has been preparing for the insect's arrival since the adoption of our EAB plan back in 2016. Like most Minnesota cities, North St. Paul has an abundance of ash trees growing on public and private property. A 2010 DNR survey found more than 1,400 ash trees. It is estimated that over 30 percent of trees in the Twin Cities area are ash trees. EAB kills unprotected ash trees, which become a safety risk due to dry brittle wood.


Citywide Resident Discount Now Available

The City of North St. Paul has chosen Rainbow Treecare as its contractor to treat public ash trees. A citywide discount is being offered to North St. Paul homeowners for trees on private property that are at least 10" in diameter and in good physical condition. Rainbow Treecare will inspect tree(s) at no cost, confirm they are ash, and help determine if treatment is the best option. Rainbow Treecare offers a money-back guarantee for North St. Paul residents if your tree dies from EAB while under continuous protection.

Benefits of the City of North St. Paul’s Ash Injection Program

In areas with high EAB populations, trunk injections have achieved a higher success rate, and protect the tree longer than soil-applied treatments. The citywide bulk discount provides homeowners with an affordable option for managing their ash trees for long-term protection. 

For more information contact Rainbow Treecare for the citywide discount at Rainbow TreeCare or call Rainbow Treecare directly at (952) 767-6920.  

The City is advising residents to watch for signs and symptoms of EAB on their private ash trees. More information on EAB and management options for private ash trees can be found here.

 The City of North St. Paul is doing preemptive removals in conjunction with street projects. This is an appropriate opportunity to reduce the high percentage of large ash trees on the boulevards that will otherwise be dying all at once in the near future. In response to specific concerns, they have checked the upper canopy branches of certain trees using an aerial lift.


There is a wealth of information on the internet about EAB, including maps, how to identify it, the latest research, and advice on how to fight it, both for the individual tree owner and as a community, and the consequences of not doing so, such as the loss of property value.
