Sapsucker Woodpecker Holes in Crepe Myrtle Bark

A 24-year-old crepe myrtle in Fort Worth developed 1-5 inch holes in bark; no photo available.

Diagnosis

Without a photo, the most likely cause of holes in woody trunks (rather than borer tunnels) is the yellow-bellied sapsucker, a woodpecker that drills orderly rows of ¼-inch holes to feed on sap and attracted insects. Holes often appear in straight rows or columns, sometimes encircling the trunk.

Assessment

Sapsucker damage rarely kills trees but can weaken them, inviting secondary pests. The tree will naturally heal holes. No treatment is needed unless damage is severe. Insecticide on the trunk can reduce insect attraction, discouraging the bird.
