In the past few weeks, you may have notice weird looking funnel traps near walnut trees.
These traps are used to captures the walnut twig beetle. It's a beetle that carries the thousand canker disease.
The beetles only attack black walnut trees. Once infected, the tree develops thousands of cankers and slowly dies.
"It doesn't kill the tree immediately, but it does after several years, and one of the things that made it so confusing when we first found it is that we had a lot of tree stress and and die back from the drought, and the same things you see from drought are the same things we'd see from the thousand canker disease," explained Knox County Extension Agent David Vandergriff.
It's important not to use firewood from counties containing these infected trees.
