It is believed to have entered the United States by stowing away inside cargo from China. It is estimated to have wreaked billions in damage since its arrival around 24 years ago. It is the emerald ash borer, which kills its namesake tree by devouring the cambium layers beneath its bark.
The pernicious jewel beetle has already destroyed millions of ash trees in Minnesota. “It’s currently one of our biggest focuses, and will stay that way for the foreseeable future,” said Aaron Athmann, owner of A + A Tree & Landscaping.
“Thinning of the leaves around the tree’s canopy. D-shaped holes through its bark. Squiggly paths appearing on wood just beneath the bark. Vertical cracks in the bark, or a dense cluster of sprouts around the tree’s base. If you’ve noticed any signs of emerald ash borer infestation, call (952) 426-8234 today for a thorough inspection. If a tree is too far gone for treatment – which we also provide – then it’s imperative to cut it down before it becomes a serious safety hazard!” APlusATree.com
