What Does Tree Borer Damage Look Like?

The initial indicators of a borer attack on trees include the appearance of sawdust-like material and sap or resin oozing from small holes on tree trunks and branches. The tree bark exhibits swelling, knotty formations, calluses, and may develop cracks leading to small areas breaking off. Tree borers, primarily in their larval stages, are chewing insects that consume the inner bark and/or wood of trees, with most species being the larvae of beetles like the Emerald Ash Borer, Locust Borer, Bronze Birch Borer, and Longhorned Beetles. These invasive pests cause significant harm to ash trees, compelling many homeowners to replace trees that die due to infestations.

Tree borer damage leads to the gradual weakening of trees because their chewing disrupts vital transport tissues. Over time, they can girdle trees or weaken branches to the extent that they may break under pressure. Specifically, the lesser peachtree borer targets older trees, infesting their upper trunks and main branches near wounds or damaged areas, indicated by brown frass mixed with sap and gum. An infested tree may display thinning crowns, epicormic sprouting, and potentially resemble drought-stressed trees, making early detection crucial.

The emerald ash borer (EAB), originating from Asia and first detected in the U. S. in 2002, is particularly destructive as it attacks all North American ash tree species, including white, green, and black ash. Early signs such as D-shaped holes, discolored leaves, dieback, and frass are essential to identify borer infestations before they cause irreversible damage, often leading to tree mortality within a few years.
