SEATTLE -- The world’s largest hornet, which has an appetite for honey bees, has been found in Washington state, where entomologists were making plans to wipe it out.
The hornet was sighted for the first time in the U.S. last December, when the state Department of Agriculture verified two reports near Blaine, Washington, close to the Canadian border. It also received two probable, but unconfirmed reports from sites in Custer, Washington, south of Blaine.
The hornet’s life cycle begins in April, when queens emerge from hibernation, feed on plant sap and fruit, and look for underground dens to build their nests. Hornets are most destructive in the late summer and early fall. Like a marauding army, they attack honey bee hives, killing adult bees and devouring larvae and pupae, WSU said.
Their stings are big and painful, with a potent neurotoxin. Multiple stings can kill humans, even if they are not allergic, the university said.
Farmers depend on honey bees to pollinate many important northwest crops such as apples, blueberries and cherries. With the threat from giant hornets, “beekeepers may be reluctant to bring their hives here,” said Island County Extension scientist Tim Lawrence.
