Spokane, Washington (AP) — Washington officials said Thursday that they had destroyed the first giant Asian wasp nest of the season near the town of Brain on the Canadian border.
The Washington State Department of Agriculture said it had eradicated the nest on Wednesday.
The nest is located at the foot of a dead Hannoki tree in the countryside of Whatcom County, about two miles (3 km) from the nest eradicated by authorities last October, from where residents reported live sightings of Asian giants. It was about 1/4 mile away. Wasp on August 11th. The site is about a quarter mile from the Canadian border.
The giant hornet is sometimes called the murderous wasp because it preys on other bees.
The giant hornet is the largest wasp in the world and is not native to North America. They prey on bees and other insects. They can make a mass attack on the bee hive and destroy it within hours. Wasps were first detected in the United States in 2019, when wasps were reported in Whatcom County.
Insects 2 inches long (5 cm long) threaten honeybees and native wasp species. Although not particularly aggressive to humans, their stings are very painful and can be killed, although they are rarely repeatedly stung.
State workers in hazmat suits began eradication on Wednesday by vacuuming 113 wasps from their nests. The team then began removing the bark and rotten trees near the roots of the alder trees. Removing the tree revealed that Hornets had excavated the interior of the tree to create space for a nest of nine layers of combs.
The part of the tree with the nest was cut out and taken to the Washington State University Extension in Bellingham for further analysis. The nest itself contained about 1,500 wasps at various stages of development.
WSDA entomologist Sven Spichiger said: “We expect there to be more nests there, and thus hope to find them before they can spawn a new queen.”
