Emerald Ash Borer
Does the emerald ash borer sound familiar? It's a flying beetle, just over half an inch long, that attacks one type of tree in particular: ash trees. Its larva digs galleries inside and the insect attacks the leaves. The beetle is native to Asia and entered North America in 2002. How does it travel? In ash trees or the raw wood or bark of this species, or in logs, packaging, pallets or crates made of this wood. In Quebec, we are also fighting against this beetle.
Consequences for ash
The time before an infested tree dies usually varies from as little as one year to about 5 years. The determining factors of this time are its age and size. The galleries made by the larvae eventually compromise the circulation of sap, which feeds the trees. Visible signs are balding or early yellowing of the crown or leaves. Damage to the bark may also be visible. Often, a half-attacked tree has to be felled. This is often enough to make the damage irreversible. However, the felling must take place outside the propagation period (mid-March to mid-September). When this happens, it is important to include the removal of the affected trees. Our tree care company can advise you on how to deal with this plague and can cut down and grub the trees as needed.
