Abe Nielson, Kentucky Division of Forestry, reported emerald ash borer-infested trees were found in Floyd, Lincoln, and Martin counties during the last 2 weeks in. The most current distribution map is located at the UK Emerald Ash Borer Information website.
Emerald ash borer larvae in trees begin to mature in September, and they all should be finished feeding by October. Full-grown larvae spend the winter in cells that they chew in the outer bark or just under the inner bark (Figure 1) within the outer inch of sapwood.
