Dogwood borers are found in the Eastern U.S wherever dogwoods are grown. Though they prefer dogwood, they can be found on oak, chestnut, hickory, elm, willow and pecan trees.
WHAT TO LOOK FOR
These insects bore into tree bark and cause ugly scars. Brown grass around bark cracks or wounds may indicate an infestation.
Insecticides can help control dogwood borers as well as taking proper care of dogwood trees. Kousa dogwood trees appear to have some resistance.
