The documentary, currently streaming on Discovery+, opens with some spectacular carnage. An amiable beekeeper named Ted McFall provides a gruesome look at what happened to his honeybee hives when the hornets showed up in his Whatcom County, Washington, bee farm: wholesale slaughter. McFall chokes up talking about the unexpected deaths. As a professional beekeeper who makes his living selling products like honey and beeswax, the appearance of the Asian giant hornet on his property was an existential threat, and he couldn’t help but take losing his bees personally. Attack of the Murder Hornets follows McFall as he joins a loose alliance of beekeepers and scientists in the Pacific Northwest who hunt for the nests of these invasive insects, racing to remove them from the local ecosystem before they wreak havoc.
Another member of this mission is Washington State Department of Agriculture entomologist Chris Looney, a dedicated, loquacious scientist who treks through the woods with a net, undaunted by the long-shot nature of his quest. Although the team lays traps, their breakthrough comes from a tiny bit of high-tech gear: Roboticist Vikram Iyer realizes that tracking devices created for robotic flies might also work if attached to the Asian giant hornet, so the gang commences with capturing individual hornets and gluing trackers to their abdomens until one finally leads them back to the nest. Although they encounter a series of roadblocks, Stephenson’s subjects are able to capture a large portion of the hornets, including many young queen specimens, which would have spread the problem all over the region had they grown up and started their own nests. Science doesn’t totally save the day, but it staves off disaster.
Stephenson’s documentary moves at a thriller’s brisk clip, and he’s so immersed in the ad hoc murder hornet detective squad that people speak candidly to him. He captures their pursuit from an intimate vantage, picking up quiet moments such as a local child crying at the sight of a hornet whose wings have been accidentally glued together in an attempt to attach the robot tracker. And it’s a passionate, engaging group: They’re all out in the forest guided by either altruistic hopes for science or a real crusader’s zeal. (“If we’re unsuccessful at getting rid of this murder hornet, God help us all,” McFall says.) The story is a compelling ecological race against time, with real stakes: When honeybees are in danger, the entire food chain is also at risk.
With so much built-in drama, ambiance, and character, Attack of the Murder Hornets didn’t need to lean on its nature-doc-as-crime-doc gimmick as hard as it does, with its ominous soundtrack and horror-movie graphics. Most of the scientists interviewed are careful to note that the insects themselves are not to blame for following their instincts. (McCall, however, laments that he cannot behead each and every hornet himself.) Beekeeper Conrad Berube, who eradicated the first nest discovered in North America, is brought in to help with the mission; though he favors vests embroidered with bees and is clearly reverent toward insects, he’s called the “trigger man” since he has experience destroying these habitats. Yet he holds no animus toward the hornets he feels obliged to destroy. “Look how beautiful she is,” he says when he sees a queen. “There’s a certain pang of being involved in its eradication.” He explains that he helps to kill the creatures only to protect the ecosystem.
