Liriope's Muse: Is Your Tree Infested with Borers? Here's How to Tell
As a Board-Certified Master Arborist, one of the biggest threats I see in urban and residential trees is borer infestation. These invasive insects tunnel into trees, feeding on their internal tissues, bringing pathogens, and often causing irreversible damage. The sooner they're detected, the better chance you have of saving your tree—and protecting the rest of your landscape!

Here are several signs your tree may be suffering from a borer infestation:
1. Sawdust at the Base of the Tree: This is often one of the first visible signs. As borers tunnel into the wood, they push out fine sawdust-like material called frass, which collects around the base or in bark crevices.
2. Toothpicking: Some species of borers leave behind small, pencil-lead sized toothpicks of frass protruding from the bark. This striking symptom is a clear indicator of active borer activity.
3. Holes in the Trunk or Branches: Small, round or oval exit holes can be seen on the bark where adult borers have emerged. These holes vary in size depending on the insect species but are a telltale sign of internal damage.
4. Dripping Sap or Wet Spots: Trees may ooze sap from entry points, which sometimes mixes with frass or sawdust. This can result in discolored streaks or wet-looking areas on the bark.
5. Thinning Canopy and Loss in Vigor: If a tree is losing leaves prematurely, showing sparse foliage, or experiencing dieback in the crown, it may be due to the disruption of nutrient flow caused by borer damage.
6. Cracked or Peeling Bark: As the tree tries to compartmentalize the damage, bark may begin to crack or fall away, revealing internal galleries chewed by the larvae.
7. Presence of Woodpeckers: An increase in woodpecker activity may indicate a hidden borer problem, as these birds feed on the larvae inside the tree.
If you recognize one or more of these symptoms in your tree, it’s crucial to act quickly. Borer infestations can kill trees in a matter of seasons and spread to nearby healthy trees, turning one problem into many.
Contact a Certified Arborist immediately for an accurate diagnosis and treatment plan. With timely intervention, it's often possible to stop the spread and preserve your trees for years to come.
