Emerald Ash BorerThe Emerald Ash Borer is a flying insect with a shimmering shade of green on its body. It is a member of the beetles. As an adult, it grows to about half an inch in length. They are called "ash trees" simply because they attack ash trees. When mature, the insect eats the leaves of the tree, but its white larva lives in the tree and builds galleries.
This insect came to us from Asia. It was in 2002 that it began to be spotted in North America. How did it get to us? By transporting various objects made of ash: crates or pallets for transport or firewood. It is also by these means that the insect travels within Canada, expanding its territory. Its after-effects on the ash treeIt is very difficult to get rid of this insect, called invasive. Why is it so hard to get rid of? Simply because it has no natural predators in North America. In less than five years, it can kill a tree; sometimes a single year is enough. Usually, the degradation process goes through four stages. The first one takes 2 to 3 years, and then it is difficult to detect the signs of the insect's presence because they do not really appear.
