Emerald Ash Borer Guide and Resources
Adult EAB beetles lay eggs in the bark of the tree. As the larvae grows, it eats through vital transportation tissue in the ash tree’s trunk, which limits the movement of water and essential nutrients in the tree, causing it to die. Tens of millions of ash trees have died throughout the United States, and cases of EAB have been discovered in every county in Illinois. Government regulations have minimized the spread of EAB across state lines, while professional arborists can protect trees from EAB before they are affected.
In this guide, you will find links to helpful websites and resources — from basic guides to government resources — about the EAB problem both here in Illinois and throughout the United States. Links marked with this icon are PDFs or other documents.
Emerald Ash Borer (EAB) is a beetle native to Asia but has invaded North America in recent years.
