Confirmed in Washington.

The world's largest species of hornet invaded Washington state in December.

Now, seven months later, state officials have finally managed to catch one of the "murder hornets" — but they have less than two months to catch the rest before mating season begins and the species has a chance to grow.

The Washington State Department of Agriculture announced on Friday that it captured its first Asian giant hornet on July 14 in a bottle trap near Birch Bay in Whatcom County. A lab confirmed the hornet as part of the invasive species on July 29.

This was the first time the state found a murder hornet in a trap, rather than in the environment, a WSDA press release said. There have been five prior confirmed sightings of the hornet in the state. Sven Spichiger, managing entomologist for the state department, said the finding is "encouraging" because they now know the traps work.

This 2013 Chinese news article describes the problem these hornets caused in Shaanxi province ...
Death toll from terrifying giant hornets rises to 41, over 1,600 injured

The death toll from a plague of giant, highly-aggressive hornets sweeping through Shaanxi province has risen to 41, with over 1,600 people injured, Shanghai Daily reports.

As you can see in the photo above, these hornets/wasps are big. Asian giant hornets (vespa mandarinia) are on average 5.5 cm (2.2 inches) long, or about the width of an iPhone 3G.

Though hornet attacks are a fact of life in Shaanxi, this year the insects have been especially prevalent, scientists suggest the greater numbers may be caused by increasing temperatures brought on by climate change.

The hornets, which can reach speeds of up to 40 kilometres per hour (25 mph), are also extremely aggressive. One man described being chased for 200 metres and stung repeatedly for over three minutes.

"The more you run, the more they want to chase you," said another victim, whose kidneys were ravaged by the venom. When he was admitted to the hospital, his urine was the color of soy sauce, according to local reports.

Authorities in Shaanxi have established a team of medical experts to offer support to victims. Firefighters have also been equipped with pesticides and protective clothing to tackle the insects.

Tag, Trace, Terminate.

The race is on to keep Asian giant hornets from spreading in the Pacific Northwest.

Fifteen hornets — including 11 dead ones — have turned up in Washington state since 2019, as well as others in British Columbia, Canada. “We’re pretty sure there’s at least one nest” somewhere near Birch Bay along the Washington coast, says Karla Salp, a spokesperson for the Washington State Department of Agriculture in Olympia.

Efforts are under way to attach a radio tag to a live hornet and track it back to a nest. In an Oct. 2 news conference, department officials described catching their first live giant hornet just east of Birch Bay. The team glued a tiny transmitter to its abdomen. “Unfortunately the glue did not dry fast enough,” entomologist Sven Spichiger said. The tag fell off and glue got on the hornet’s wings, ruining its ability to fly.

The department is using live traps and “sentinel hives” — honeybee hives with a grate that allows bees to pass through but stops the larger hornets — to attract more hornets. The goal is to find and destroy any nests, ...
