Why Winter Can’t Save Trees From Emerald Ash Borers

Because we live in an area that has cold winters, we can often rely on these chilly temperatures to help us get rid of some annoying plant and lawn pests without treatment. But when it comes to the invasive emerald ash borer, this approach unfortunately does not work. While the cold may kill a few of the emerald ash borers in your ash trees, it will not kill all of them.

Emerald ash borers are a very sturdy tree pest. They burrow deep inside of trees before winter hits in order to hibernate. The insulation from the tree, plus their hibernation cycle, help them to survive throughout the winter. Exceptionally cold temperatures may kill weaker borers, or ones that are inhabiting smaller, younger trees. But the healthier the borer, the more likely they are to survive. This means that, after a particularly harsh winter, you may be left with only the toughest emerald ash borers. This can make it even more difficult to eradicate them during the spring, and that, if they are allowed to breed, they will produce even heartier offspring.

With this in mind, the best approach to preventing and treating these destructive pests is in watching your trees for signs of an emerald ash borer infestation. The signs are often the most noticeable during the fall and winter, when leaves have fallen which allows you to better see the state of the bark and branch attachments. Bark splitting, S-shapes under the bark of your trees, and increased woodpecker activity may all be signs of impending trouble.

If your trees become infested with emerald ash borers, it can take just two to four years for the tree to die if left untreated. In addiction, the borers can spread to neighboring ash
trees, quickly decimating an entire neighborhood.
