Ultra-aggressive killer hornets attacked officials after they arrived to remove the nest they had built
Washington state officials said last month they had destroyed Asia’s first giant wasp nest of the season, but that didn’t stop the invasive insects from attacking officials.
Washington State Department of Agriculture entomologist Sven-Erik Spichiger said in a recent news conference that this group of so-called killer hornets was “more aggressive” than the one found in 2020.
Spichiger added that when vacuuming the hornets to remove them, the hornets exploited the hole in the rotting tree where the nest was and they became aggressive.

“When we started vacuuming, because the tree was so rotten, the hornets could take advantage of this and create a second opening and they came out.

“A few of us working closely in the area were approached by the hornets and this time they tried to sting us.”
No one was injured in the attack and the extraction was completed in “just a few hours,” Spichiger explained last month.
The team eventually removed the bark and decaying wood near the bottom of the alder tree that provided access to the nest, which had nine layers of comb.
The nest, located near Blaine in Whatcom County along the Canadian border, was eradicated on August 25

The rotting tree was near Blaine, Washington in Whatcom County, along the Canadian border.
The nest was exterminated. WSDA officials vacuumed 113 worker hornets from the habitat.
The Washington State Department of Agriculture (WSDA) has sucked up 113 worker hornets from the habitat. They also captured 67 additional hornets in the netted area during the mission to destroy the nest, which itself had nearly 1,500 hornets in various stages of development.
In addition to the worker hornets vacuumed from the tree, WSDA employees captured 67 additional hornets in the area with nets during the mission to destroy the nest, which itself had nearly 1,500 hornets in various stages of development.
Part of the alder tree was also cut down and sent to a Washington State University lab in Bellingham for further analysis.
The nest was located about 2 miles from another nest the agency exterminated last October and about a quarter of a mile from where a resident reported a live sighting of an Asian giant hornet on Aug. 11.
Asian hornets were first discovered in the US in 2019 when a hornet was reported in Whatcom County. The nest, which housed 500 workers and 200 queens, was destroyed during surgery on October 24 (pictured)
The nest was discovered after officials captured three hornets and fitted them with tracking devices between August 11 and 17.
The Asian giant hornets — the world’s largest hornet at two inches — are sometimes called killer hornets because they prey on other bees.
While these invasive insects kill honeybees and Native American hornets, they aren’t very aggressive towards humans.
However, their sting is extremely painful and repeated stings, while rare, can be fatal.
Despite this nest having been eradicated, officials say it is imperative that the public continue to help find this invasive species, which can decimate entire hives of honeybees, already besieged by mites, diseases, pesticides and loss of honeybees. food.
In March, Washington State said it was… making plans for the Killer Hornets’ 2021 season, similar to last year’s, with an emphasis on audience reach, reporting, and traps.
Hornets kill honeybees, which are already plagued by mites, diseases and other factors. They have an extremely painful sting and are the world’s largest hornet, measuring five centimeters in length
More than half of confirmed sightings of Asian giant hornets in Washington and all in Canada came from the public, WSDA has previously stated.
The first confirmed detection of the hornet in the US was near Blaine in December 2019 and the first live hornet was captured in July 2020.
The invasive insect is normally found in China, Japan, Thailand, South Korea, Vietnam and other Asian countries.
‘The hornets enter a ‘slaughter phase’ in which they kill bees by decapitating them. Then they defend the hive as their own nest and take the brood to feed their own young,” the WSDA said earlier.
The agency has already killed six or seven hives in Washington state.
Despite their nickname, the hornets kill at most a few dozen people a year in Asia, and experts say it’s probably much less, but they do deliver painful stings to people.
Hornets, wasps and bees typically found in the U.S. kill an average of 62 people each year, according to the Centers for Disease Control and Prevention.
Murder Hornet Stats
Latin name: Vespa mandarin
Adult height: 1 3/4 inch
wingspan: Three inches
stitch length: Quarter of an inch
Description: Yellow face and large black and yellow striped belly. Big jaws and a noisy flier.
Asian giant hornets are more than twice the size of honeybees and have a wingspan of more than two inches
Natural habitat: Throughout Asia
Venom: It delivers seven times more venom than a honeybee when it stings. This acts as a neurotoxin and can lead to seizures and cardiac arrest. The sting is described as incredibly painful.
Behaviour: Insect emerges in April and nests in the ground. It predates many insects, but mainly targets honey bees.
risks Has a habit of sacking beehives, beheading the workers and stealing the young. The European honey bee has no defense against the invader. Its stings can also be deadly to Americans.
