What are tree borers?

Tree borers are chewing insects, usually in larval stages, that chew and feed on the inner bark and/or wood of trees. Most species are the larvae of beetles. Some are woodboring caterpillars or other insects.

How do you identify borers?

The most obvious signs of tree borer insects are the tiny holes they cut into trunks, branches, and stems. These holes may be perfectly round or slightly oblong, sometimes a sawdust-like material, called frass, falls on branches below these holes or forms a long cylinder as tree borer insects excavate tunnels.
