Woodpecker Damage on Weeping Willow: Sap Suckers

A weeping willow shows numerous holes and darkening trunk from woodpecker activity. This is likely sapsucker damage: the birds drill holes to drink sap and eat insects attracted to it. The tree is not seriously harmed. Spray the trunk with an insecticide (malathion, Sevin, or home defense spray) to kill insects, which will discourage the birds. The wounds will heal naturally without further intervention.

Action Plan

1. Apply insecticide to the affected trunk area.
2. Reapply as needed per label.
3. Monitor for new holes; the tree will compartmentalize the wounds.
