Sapsuckers can damage trees in nurseries and landscapes. The damage is sometimes mistaken as insect damage. Sapsucker damage is often in rows that makes identification easy. But sometimes, the damage is less linear and dispersed as they chew to obtain sap from the trees. They feed by chewing "sap wells" in the bark in which they can feed on the sap.Their feeding is rarely as deep as damage from other woodpeckers feeding on insects under bark.
Most methods to mitigate damage involve exclusion (burlap or other wraps) repellents (usually sticky types), visual and noise scares. See resources below for more information.
