What type of damage do sapsuckers inflict on trees?

Sapsuckers make small holes in the main trunk or large branches of trees. These holes are usually in a row or pattern which is characteristic of sapsuckers. Just what exactly is a sapsucker? Sapsuckers are a type of woodpecker which makes holes in a tree and uses its tongue to remove sap. They usually have a few favorite trees and may leave nearby trees completely untouched. What can be done to prevent the sapsuckers from damaging a tree? Usually with them out of sight means out of mind. Wrapping burlap loosely around the damaged area and tying it in place is usually enough to cause the sapsuckers to look for other targets. If it blows in the wind that will also scare them. Can they kill a tree? Yes, if they continue working on a particular tree it may eventually die. The sap leaks out the holes and doesn't get up to the leaves and branches. Pruning paint doesn't help seal the holes because the sap pressure is from inside.  more
