“We hope to find the nest in a few weeks and eradicate it,” Spichiger advised the outlet.

An company spokesperson additionally advised the Instances that officers caught their first dwell specimen this week. They meant to equip the hornet with a tracker in order to observe it again to its nest, however their first try failed spectacularly. On Wednesday, officers tried to attach a radio tag to the hornet, however not solely did the glue not dry quick sufficient, inflicting the tracker to slide off, it additionally caught to the hornet’s wings and made it unable to fly.

“You do must be very affected person and wait until it dries,” Spichiger stated. “However if you’re dealing with an Asian big hornet, clearly, it doesn’t need you dealing with it.”

The staff arrange 30 traps baited with orange juice and rice wine all through the world to try to seize one other, the Instances stories. At Friday’s press convention, Spichiger stated the division was assured it could catch one other dwell specimen inside the subsequent few weeks.

“It might be a really daunting activity to search out the precise location,” he added. “However, you realize, that’s what we’re all ready for, and looking out ahead to—discovering that nest and taking it out.”

Within the meantime, the company has established an emergency hotline “just like 911” for beekeepers to contact if their hives come beneath siege.

In August, officers efficiently captured their first two specimens, a queen and a male, proving that their DIY traps labored. Asian big hornets are the biggest on the earth at 2 inches (5 centimeters) so conventional hornet traps simply received’t reduce it.

As their title would counsel, Asian big hornets are native to China, Japan, and different Asian international locations. Consultants are nonetheless making an attempt to determine why the species started showing in Washington State and the Canadian province of British Columbia final fall, with the prevailing concept being that they could have unintentionally hitched a experience on a cargo ship or aircraft.
