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.
