Common Invasive Tree Insects

Last summer the word on the tree street was all about the Emerald Ash Borer. Sadly, there are pests aplenty for pretty much any tree around though and more often than not, there are insects that aren’t picky about which trees they infest. Do you know what to look for when it comes to your trees? Here is a list of some of the more common invasive species to watch out for;

COMMON INVASIVE TREE INSECTS

Asian Longhorn Beetle

      • Asian Longhorn Beetles – prefer to attack maples, but will bore their way into poplars, elms, willows, mulberries and other trees, effectively destroying the tree from a combination of their larvae eating the tree’s internal tissues & the tree’s food supply being cut off
      • Bronze Birch Borer – attacks stressed birch trees by feeding under the bark & effectively girdling the tree, leading to dieback of upper branches, swollen ridges on the trunk & limbs and eventual death

Cedar Leaf Miners

      • Cedar Leafminers – are not always fatal to cedar trees, but if left to feed off the leaves, tunneling through the branches for several years in a row, they can overwhelm the specimen
      • Dutch Elm Disease – is a devastating fungal disease to Elm trees, primarily spread via the elm bark beetle, which kills the tree by preventing water movement throughout the tree
      • Emerald Ash Borer – has steadily moved north and is now ravaging ash trees in Southwestern Ontario. Ash trees can be rapidly overcome as the quickly reproducing borers feed on the tree’s cambium, leaving behind severely compromised and brittle trees that face death unless identified early

Gypsy Moth

      • Gypsy Moths – defoliate mass amounts of hardwood trees across North America each year
      • Hemlock Wooly Adelgids – are soft-bodied aphids that feed on Hemlocks with their piercing mouths that literally suck the life out of trees
      • Pine Shoot Beetles – originally had a taste for Scots pines, but have recently been found to attack other pine species as well, by boring into the shoots and ultimately into the main trunk of the tree causing death in as little as 2 years
      • Tent Caterpillars – infest sugar maples, aspen & oak, but will eat foliage from other hardwood species as well, stripping them bare in short order and devastating weak trees during heavy infestation years

And sadly folks, that is just the tip of the iceberg…

  1. Over in Western Canada those pine beetles have been a real problem. And with this mild winter we just had I bet this will be a very bad year for them, although that means a good year for tree removal services.
    As a separate question, what type of chainsaws do you use? I run a website that gives information of buying chainsaws and am always interested to hear what people like and don’t like and what brands are good/bad etc.

    Thanks,
    Stephan

    • I completely agree on the winter and the effect it will have on bugs. I would prefer any other way to increase business, but you are right about it probably increasing this year Stephan. As far as kind of chainsaws that we use, we use all Husqvarna and Stihl exclusivley.

      Thanks so much for stopping by. We look forward to you visiting again soon.
