Learn About the Locust Borer Beetle!

Locust_borer_wikiIn North Carolina and other states on the East Coast, the locust borer beetle is an endemic. This beetle originally lived in just the Allegheny Mountains and the Ozark Mountain region. But over the years, it has gradually moved to new locations and unfortunately has become a major pest problem in the United States.

How to Know When Your Home Is Infected

The main way that people can spot the presence of the locust borer is by looking at their trees. Borer larvae like to tunnel into a tree's branches. This causes the tree to weaken and deformed branches begin to grow. As a result, homeowners should look for trees that have dead limbs, knotty swellings or broken branches.

In early summer, white dust may appear on the bark as the larvae push the wood dust from their holes. During early spring, wet spots will be apparent as young larvae begin tunneling into the bark. In late summer, the larvae have burrowed within the heartwood and the dust turns yellow. If there are numerous locust borer beetles present, dust may even accumulate around the tree's base.

Treatment Options

The best way to treat an attack is to prevent it from happening. Unaffected trees can be protected by spraying the trunks and large limbs with a lindane emulsion. For smaller applications, two tablespoons of lindane concentrate should be added to one gallon of water. This application should be repeated every two weeks to kill the larvae before they can get under the bark.

In a forest, since spraying chemicals like lindane or carbaryl is not practical, sometimes it requires trees to be chopped down to prevent the infestation from growing. When the forest is replanted, it is generally done with multiple tree species. Since the locust borer prefers the black locust tree, mixing other types of trees into the forest can prevent the beetle from having an area to expand into.

Professional Help

The locust borer beetle is a notoriously difficult insect to remove, and many of the pesticides to treat an infestation can only be used by a certified pest control specialist.
