ASIAN GIANT HORNET

The Asian Giant Hornet (Vespa mandarina), is the world’s largest hornet and on December 8, 2019, a Blaine, Washington resident reported finding a large dead hornet which later was determined to be the Asian Giant Hornet (AGH).

Per Washington State Department of Agriculture;

Asian giant hornets mostly nest in the ground, although nests near the ground in hollow trees have rarely been recorded. They are not known to nest in tree branches. They are social insects that form large colonies and are voracious predators of honeybees and other insects. A single hornet can kill dozens of honeybees in a few minutes and a group of hornets can destroy an entire hive by killing the adults and removing bee larvae and feeding them to their own grubs.
