Twig Girdler – Warning About this Pest

Twig Girdler – Warning About this Pest

The Twig Girdler is a beetle (gray to brown colored longhorned beetle with a gray stripe across the wing) that usually emerges from late August to early October. Small populations aren’t cause for big concern, but left untreated, these beetles can multiply into a full infestation and cause serious damage. Twig Girdler beetles girdle (cut away) twigs and small branches causing the injured portions to break away or hang loosely on the tree. The ground under infested trees is usually covered with twigs. As a result of this beetle infestation, nut/fruit trees often end up with lower yields for years. What do you do? Natural control is usually the best. Severed twigs on the ground and those lodged in  trees should be gathered and destroyed during the fall (when the females are laying eggs), winter, and spring when the eggs and grubs are still in the twigs. This way infestation can be greatly reduced in one or, in moderate cases, in two seasons. If debris infected with pests or disease is not disposed of, it can infect your trees again, or spread to surrounding trees. Twig Girdlers can be treated with systemic products that are consumed when the insect feeds on the tree. However, females don’t feed on the tree tissue, and can be very difficult to control.

If you notice small tips of branches on your trees suddenly turning brown and breaking away, call us. Our certified arborists can recommend a plan for reducing the twig girdler population and further damage to your trees.
