Trees are living things just like humans. They can become unhealthy due to exposure to pests, diseases, improper care, and drought. Pests can be one of the most common reasons for your tree to become unhealthy. Essentially, they could damage your tree and ultimately kill it altogether. To help avoid this and diagnose your tree's issue you want to get an arborist report. This will help identify the condition of your tree and provide you corrective measures to bring your tree back to life. If you believe that pests are responsible for your tree's health, then here are four of the most common pests damaging Canadian trees. 

Eastern Tent Caterpillar

One of the most common pests plaguing trees in Canada includes the Eastern Tent Caterpillar. This caterpillar may seem innocent, but it can defoliate the tree when there are many caterpillars around. To better protect the tree from the pests, you want to remove any webs that you find on it. It is best to remove the webs during the spring when the webs are filled with larvae. You can identify these caterpillars by their appearance. They are about 2 inches long and are black with a white stripe down the back. 

Peachtree Borer

You can find infestations of peachtree borer in apricot, wild cherry, plum, nectarine and more types of trees. These pests bury deep into the tree causing it to weaken. If this happens in a younger tree it can actually kill the tree due to being weak. Once the pests infest the tree, you will see a noticeable difference in the vitality of the tree. One big gust of wind could end up toppling the tree over. In order to keep the pests away, you want to make sure the trees are healthy. Any wounds and injuries can cause an infestation. Chemical insecticides can be used to keep the pests away, but you have to apply it at the trunk base and have some residual activity. 

Asian Longhorned Beetle

Another common pest that likes to damage trees throughout Canada is the Asian Longhorned Beetle. This insect accumulates through larvae and weakens the individual branches. Eventually, the tree will die if the infestation gets too bad. There is no insecticide treatment available. The best way to keep the beetle away from the tree is by keeping it healthy. A healthy tree will have a better opportunity at protecting itself. The be are shiny and black with about 20 white spots located on each wing. 

Dogwood Borer

This Canadian insect is another known pest that causes harm to many trees in the country. The larvae of the insect will feed and bury into the tree causing it to weaken. The weather can then damage it further and a young tree may not survive without care. There are several insecticides that are known to help get rid of the Dogwood Borer and keep the tree in good health.
