Asian ‘murder hornets’ descend on US, worrying agriculture officials
- Scientists don’t know for sure how the killer bug made its way to Washington state, although it could have arrived on a container ship
- The stinging Vespa mandarinia can grow as large as 6.35cm in length and is native to Southeast Asia, China and Taiwan
Hundreds of Asian giant hornets, an invasive, predatory insect dubbed the “murder hornet,” have turned up in Washington state near the Canadian border, where they pose a threat to humans and the beekeeping industry, state agriculture officials said.
The stinging Vespa mandarinia can grow as large as 6.35cm in length and is native to Southeast Asia, China and Taiwan. It was first discovered in Blaine, Washington, in December by a homeowner, according to Sven-Erik Spichiger, managing entomologist at the Washington state Agriculture Department.
“An Asian giant hornet can sting you multiple times and deliver larger doses of venom just because of the size of them. The venom itself is fairly toxic and creates localised necrosis around the wound so you’ll see melting flesh around the wound,” Spichiger said.
“What we’re told from the literature is that most people can survive one or two stings,” he said. “But if you sustain multiple stings, the necrosis and the venom will actually start getting into your bloodstream and will start working on your organs. And multiple stings could literally be fatal.”
Aside from the danger to humans, the “murder hornet” presents a danger to agriculture and the apiary industry, Spichiger said, because the insect is known to attack honey bees, with a few of the hornets capable of wiping out an entire hive in hours.
