Giant Hornets in Beech Tree: Identification and Control

Large (2-inch) black-and-yellow striped insects boring into a beech tree in Virginia, removing wood chunks. Wasp spray foam failed.

Identification

European giant hornet (Vespa crabro). Nest in tree cavities, excavate wood.

Effective Control

Use foaming hornet spray (e.g., Bengal) directly into entrance at night. Foam coats insects entering/exiting. Standard aerosols often fail due to nest depth.
