Bugs That Destroy Trees

Bugs That Destroy Trees There’s no doubt bugs are an important part of any ecosystem, but they can also spell havoc for trees, sometimes weakening them to the extent that they need to be felled.

There are three types of destructive bugs that destroy trees: Chewing insects (that eat fruit and leaves), boring insects (that burrow into the trunk, branches, and roots), and sucking insects (that suck fluid from leaves and twigs).

1. Gypsy Moth

The Gypsy Moth is a chewing insect. It lays eggs in the spring which then hatch into hungry larvae that defoliate the tree. Munching their way through leaves, they rob the tree of energy which can eventually lead to the death of the tree.

Prevention & Treatment Tip: Healthy trees are more resilient to these types of bugs, so it’s a good idea to make sure you’re tree is well pruned and has enough water.

2. Emerald Ash Borer

These are (as the name suggests) boring insects. They burrow into the ash tree’s vascular system, disrupting its water and nutrient supplies and killing it within 8 years.

Prevention & Treatment Tip: Proper pruning and removal of dead limbs to prevent infestation. Adequate water, mulch and fertilization will also help strengthen your trees.

3. Aphids

The teeny tiny aphid is a sucking insect. It sucks the sap out of tree leaves, leaving them puckered, yellowed and twisted. In large numbers they contribute to leaf drop and twig / branch die back.

Prevention & Treatment Tip: Spraying the underside of foliage with an insecticide is the best course of action for large outbreaks.
