Emerald Ash Borer Treatment Times

Emerald ash borer (EAB) the destructive, invasive insect pest that attacks and kills ash trees has been confirmed in 45 of Iowa's counties.  Iowans who want to protect their ash trees from attack can use one of several insecticide application techniques to put specially-formulated insecticides into the tree to kill EAB adults and larvae. Treatment is warranted only to valuable and healthy ash trees within 15 miles of a known infestation of EAB. The best time to apply most insecticides is in April and May, though other windows of treatment opportunity exist for some products.  Learn more about treatment options in the Iowa State University Extension & Outreach new release for April 19, 2017.  The article includes links to ISU pamphlet, “Emerald Ash Borer Management Options,” available in English (PM2084) and Spanish (PM2084S).
