With the discovery of EAB in Brown County, The Village of Ashwaubenon (consistent with UW-Extensions recommendations) encourages residents to chemically treat ash trees to prevent being killed by EAB. Since limited resources preclude us from treating large numbers of the over 1,475 street and park ash trees, residents are encouraged to treat street trees on a preventative basis. Property While research has shown that no product is 100% effective, a number of effective options are available and may be done by homeowners while others require professional applicators. Below are links to publications with the latest, research based information about treating for EAB:

Many people choose to make annual spring applications in April (right around the time that folks are getting their gardens in order).
