With reports of Emerald Ash Borer infestations in southeast Iowa, some may be wondering how to spot one. According to Iowa State University Extension Entomologist, Mark Shour, a noticeable symptom is a loss of leaves.

He says if its affecting 20% or less of the tree, treatment is possible, but if its worse than that, its too late. Insecticide treatment should be done in the spring, and is only recommended if the tree is within 15 miles of a confirmed infestation.

If you think one of your trees is infested, contact your local extension office.
