Sapsuckers -- Yellow Bellied
Sapsuckers will peck horizontal and vertical rows of holes in the trunk and upper branches of the trees. NO INSECT CREATES VERTICAL AND HORIZONTAL ROWS OF HOLES EVENLY SPACED AND IDENTICAL. Most damage occurs as birds are migrating through Illinois in early spring (April through May) or late fall (September and October).
Sapsuckers create the holes and feed on sap. They may occasionally feed on insects foraging at the exposed site. Birds will continue to come same trees during migration and peck in the same areas. Insects and disease organisms can enter the tree at the point of sapsucker injury, creating further problems for the plant. Severe and repeated injury can kill parts of or the entire tree.
Wrap damaged areas of trees with a loose, coarse material such as burlap to prevent pecking and feeding. Fertilize and water the tree to stimulate growth.
