On October 24, entomologists eradicated the first-ever US nest of the enormous Asian insect in Blaine, north of Seattle, by utilizing a vacuum to suck them out.
The scientists had connected radio trackers to a few bugs caught in a entice, with one main them to their nest. The nest was then eliminated by members of the Washington State Division of Agriculture’s (WSDA) Pest Program.
It contained 108 cells, which appeared like queen hornets able to emerge, whereas one other 76 had already spawned, in response to the state agriculture officers.
After opening the nests, scientists discovered 190 larvae, 112 employee hornets and 9 male hornets along with the queen rely.
