Washington State Department of Agriculture entomologists, using a radio tag, have located and eradicated the first Asian giant hornet nest ever found in the United States. The Department of Agriculture’s Animal and Plant Health Inspection Service supplied the radio tag. Researchers tied the tag to a hornet, which led them to the nest in a dead tree. Two days later, a team of entomologists plugged the nest with foam, wrapped the tree in plastic, and vacuumed out the hornets. To complete the eradication, they injected carbon dioxide into the tree to kill any remaining hornets. In a recent press conference, a WSDA official noted that, given the radio tag’s strength, “I’m pretty confident as long as we can get live hornets, we can follow them back.” Now that they’ve shown that it’s possible to find and eradicate a nest, the hunt continues for any other nests that might be in the area.
