Why are my trees holey?

Woodpeckers, including flickers and sapsuckers, damage trees, homes and even telephone poles while searching for food and establishing territory.  Woodpecker damage can kill limbs or entire trees if the holes girdle the tree. The damaged areas of the tree can also attract other tree-troubles such as boring insects. The best way to prevent woodpecker damage to trees is to exclude them through the use of netting or metal barriers. Begin discouraging woodpeckers from damaging your trees as soon as they enter your area, before they establish it as their territory. Remember, it is illegal to kill these birds and decoys such as hawks or owls are ineffective.
