We suspect there could also be extra nests in Whatcom County.”
Entomologists initially noticed the nest in a tree cavity close to Blaine, Washington, after they trapped, tagged and tracked a reside Asian giant hornet again to its nest.
The profitable detection of a nest got here after a WSDA trapper on Wednesday collected two reside homicide hornets caught in a brand new sort of entice the company positioned within the space. Two extra reside hornets had been present in one other entice on Thursday, the identical day WSDA workers tagged the previously trapped hornets with radio trackers and had been capable of observe one again to its nest.
