As if honey bees didn’t have enough to contend with, from pesticides to bacterial pathogens, another nemesis has emerged in the Pacific Northwest, one capable of freaking out humans, too.

It’s called the Asian giant hornet — and is also known as the yak-killer hornet, the commander wasp in Korea and the tiger head bee in Taiwan, according to experts.

As the names indicate, the hornets are indigenous to Asia, but some appeared for the first time this month in Washington State, where agricultural officials have issued a pest alert and warned that the hornets pose a threat to honeybees.

They showed up in British Columbia in August, prompting a similar advisory from the Canadian province’s agriculture ministry.
