How Ash Borers Damage Your Trees
The Emerald Ash Borer is a wood boring beetle, with a metallic green ½ inch long body originating from Asia, and was discovered in North America, in 2002. Although the 2002 finding was in Michigan, they were confirmed in Colorado by 2013. Emerald Ash Borers have killed hundreds of millions of trees in North America since their fateful arrival.
However, it’s not them you truly need to worry about, it’s their larvae. The larvae are small white grubs that tunnel under a tree’s bark, and can cause feeding damage to the heartwood of the tree that greatly weakens your trees. And more often causing the trees to break, and in rare, more severe, cases it can even cause their death.
What trees do Emerald Ash Borers attack?
Emerald Ash Borers feed on their namesake, the Ash Tree, and with continuous feeding, can kill the trees in 3-5 years. Colorado State University states that they expect Emerald Ash Borers to eventually kill almost every unprotected Ash tree growing in North America. Since its discovery in 2002, Emerald Ash Borers have killed or seriously damaged millions of native Ash trees.
