Don’t let a small beetle turn into a big problem:
Protect your trees against the Emerald Ash Borer today.
Local ash trees are in immediate danger
Prior to 2002, North America hadn’t encountered the wood-boring pest known as the Emerald Ash Borer. The beetle’s natural range includes Eastern Europe and Asia—but it has translocated to the US in recent years. If this recently arrived menace is left unchecked, all ash trees will die due to the Emerald Ash Borer Beetle.
Healthy Ash Tree
Affected Ash Tree
Because the beetle is relatively small and the damage to the tree is mostly internal, the presence of borers is hard to detect until plants or plant parts become damaged or die. Large ash trees can die in as few as three years. Emerald Ash Borers can kill smaller ash trees in one year.
Signs that your Ash trees may be affected
Canopy dieback that begins in the top 1/3 of the tree and progress down the tree until bare. Increased Woodpecker activity/damage may also be evident.
Epicormic Shoots—sprouts growing from roots and trunk with leaves that are often larger than normal.
Bark splitting and serpentine feeding galleries beneath the bark. D-shaped holes in the bark are formed when adults emerge.
