Treating Your Ash Trees

Homeowners with ash trees have two options: treatment or removal. Treatment has been proven to save ash trees, and Naperville's own parkway ash treatment program has been very successful.

If you've treated one of your ash trees, please let the City know about its treatment. You can either submit a fillable PDF (link on the right side of the page) or download and mail the form: EAB Treatment Form
