Entomologists with the state's agriculture department had been working since December 2019 to trap and trace the movements of the so-called "murder hornets", through a network of traps set by both government officials and citizen scientists, in an attempt to locate a possible nest.
The agriculture department said in September that it hoped to find and eradicate the hornets' nest by mid-month before new queens emerge and mate, which would help it "prevent the spread" of the invasive species.
Asian giant hornets were first spotted in the USA earlier this year and can reportedly grow more than 2 inches long with a wingspan of about 3 inches.
The nest, which is about the size of a basketball and contained 100 to 200 hornets, is going to be destroyed on Saturday.
The nest is about the size of a basketball and contains an estimated 100 to 200 hornets, according to scientists, who suspected it was in the area ever since the invasive insects began appearing late past year.
Two more living hornets were found in another trap on Thursday morning, when scientists returned to attach a radio tracker to the first hornet.
"The cavity of a tree found on private property was housing the nest, and WSDA members saw dozens of hornets entering and leaving the tree".
Asian giant hornets can deliver painful stings to people and spit venom - but they are a bigger threat to honeybees that farmers rely on to pollinate their crops.
That's not to say they're harmless, though.
They were surprised that the nest was in a tree as most are assumed to be underground.
Kinda makes ya wonder. how many undiscovered nests are out there?!? In Japan, giant hornets kill between 30 and 50 people every year.
Several more of the invasive pest not native to the USA were subsequently caught, all in the same region.
