The emerald ash borer is a flying beetle that loves the leaves of the ash tree. It's only half an inch long and very destructive! It is also beautiful with its metallic green wings. Its larva prefers to bore sinuous galleries in the wood of the tree.
The insect entered North America in 2002, from Asia. It traveled in ash wood pallets or crates. Now, it has taken up residence in Canada, including Quebec, always camouflaged in anything made of ash: pallets, crates, firewood...

Did you know that an ash tree infested by this beetle can be ravaged in five years, sometimes in just one? It all depends on the age and height of the tree concerned.
It's kind of strange, the EAB starts at the top and works its way down, over the years. The drilling activity of the larvae, inside, compromises the circulation of the sap, making the specimen malnourished. The whole process takes place in 4 stages.
Stage 1: invisible action (lasts 2 or 3 years).
Stage 2: leaves yellowing prematurely, stripped crown or branches (lasts 1 year).
Stage 3: aggravation of the damage (lasts 1 year).
Stage 4: loss of bark (lasts 1 year)
