NEARLY 100 MURDER HORNETS REMOVED

Scientists removed 98 socalled murder hornets from a nest discovered near the U.s.-canada border in Washington state last weekend, including 13 that were captured live in a net, the state Department of Agriculture said Monday.

The other 85 Asian giant hornets were vacuumed into a special container when the first nest discovered on U.S. soil was eradicated on Oct. 24, the agency said.

“The eradication went very smoothly,” managing entomologist Sven Spichiger said in a news release. “This is only the start of our work to hopefully prevent the Asian giant hornet from gaining a foothold in the Pacific Northwest.

“We suspect there may be more nests in Whatcom County,” Spichiger said.

The Oct. 24 operation began about 5:30 a.m. with the team donning protective suits and setting up scaffolding around the tree so they could reach the opening of the nest, which was about 10 feet high. The team stuffed dense foam padding into a crevice above and below the nest entrance and wrapped the tree with cellophane, leaving just a single opening. This is where the team inserted a vacuum hose to remove the hornets from the nest.

Team members used a wooden board to whack the tree to encourage hornets to leave the nest, the agency said.

When the hornets stopped coming out of the nest, the team pumped carbon dioxide into the tree to kill or anesthetize any remaining hornets. They then sealed the tree with spray foam, wrapped it again with cellophane, and finally placed traps nearby to catch any potential survivors or hornets who may have been away during the operation and returned to the tree. The work was completed by 9 a.m.
