Elm Twig Drop: Twig Girdlers and Pruners Again

Daily Ring of Twig Tips Under Your Elm

The clean-cut, 1–4 inch branch tips falling daily from your elm are the work of twig girdlers or twig pruners—the same longhorned beetles that attack oaks (see Article 18210). Elm is a preferred host.

Identification & Control

Identical to oak: females girdle or larvae prune twigs, eggs develop in fallen pieces. Sanitation is the cure: rake and destroy all fallen twigs in fall/winter; prune any infested tips still attached. No insecticides needed. Damage is cosmetic unless severe and repeated.
