Asian Long-Horned Beetle
The Asian Long-Horned Beetle is a shiny jet black beetle with numerous white spots in their backs. Adults may be seen outdoors during the warmer parts of the day from summer to late autumn. They are usually seen feeding on tree leaves or branches before mating. Young larvae feed within the inner bark and sapwood and can cause the bark to become concave. Mature larvae will bore into the heartwood and coarse sawdust can be found in piles around the base of the tree or in branch unions. Adults will emerge through the wood in May by chewing round exit holes 6 to 12mm in diameter. Females will then chew oval ovipositor niches along any part of the tree about 10 mm wide and deposit a single egg. The tree reacts to this and can usually be seen as white frothy ooze on the bark. There is currently quarantine for this species within the city of Vaughan and Toronto. If you suspect that you have an ALHB infestations please call.

Emerald Ash Borer
The emerald ash borer is a shiny green beetle that kills living ash trees. The adults can be found on or near ash trees from early June to the end of august. The adults will feed along the margins of ash leaves and then deposit there eggs within the bark. The larvae stage is the most damaging stage and causes the most damage to host trees. The larvae will feed between the sapwood and bark along the entire length of the tree trunk and branches. This cuts of the flow of nutrients which eventually kills the tree. The beetle was recently found in Toronto near Sheppard and highway 404. This beetle can easily be spread through natural means through the movement of firewood, nursery stock, mulch, wood chips, leaves, lumber, and logs from affected ash trees. There is currently an investigation within a 5km radius of the discovery to assess the extent of the infestation. If you suspect that you have EAB please call.
