How to Prevent Woodpecker Damage. The best way to stop woodpecker damage is to keep the woodpecker from getting to the tree in the first place. Bird netting is a popular way to keep woodpeckers from getting at trees but other methods, such as using sticky substances on the trunk, will also work.
Misconception. Woodpeckers and sapsuckers (another type of woodpecker) are thought to kill trees. Woodpeckers do not kill healthy trees, notes Thomas G. Barnes of the University of Kentucky.

By killing insects, woodpeckers help healthy trees.
