What to do if you find an Emerald Ash Borer beetle:
Call 311 to immediately report your finding.
Place it in a clean plastic bottle to keep it from being crushed. This makes it easier to identify. Be sure to record the exact location of the tree where it was found.
Place the container in the freezer. This will preserve the insect for closer inspection.
Do not peel or remove tree bark to look for EAB larvae or galleries. This will cause significant harm to the tree, invite infection, and ultimately result in tree death. City of Edmonton entomologists and staff have authority to perform further field investigations for confirmation of EAB on public trees.
