EMERALD ASH BORER EAB #texastreeman #EmeraldAshBorer #EAB
The way this works is this treatment kills the adult beetle BEFORE she lays eggs. These eggs hatch into larva that borer perpendicular into limbs. This doesn't "kill" the limb right away. With the weight of the foliage and a gust of wind the branch, no matter how large, falls on top of whatever is under it. It's like drilling holes into the limb.
If a climber doesn't know to look for the D shaped holes that the larva makes when exiting the limb, branch, or stock that it has been boring holes into like a drill... the branch breaks easy and if an unexperienced climber isn't tied in that climber falls to the ground hitting limbs on the way down and that's big trouble.
Always make sure the person climbing your tree has a harness on and a rope that ties to the tree as a safety measure to catch the climber so he or she doesn't hit the ground bouncing off limbs on the way down.
Here's a site that I found for you that has good information about the emerald ash borer.
Please be safe and enjoy the beauty of our trees
