  • "

    Killer hornet

    " or "

    bee killer

    " - this term applies to the Asian giant hornet.

  • Scientists

    from the

    USA have

    now been able to render a nest of the insect harmless.

  • Experts warn of the

    Asian giant hornet

    : people with

    allergies

    should stay away from them!

Munich / Olympia (Washington) - employees of the

Ministry of Agriculture of Washington

(Washington State Department of Agriculture; WSDA) succeeded in a nest of

Asian Riesenhornisse

eliminate.

It is the first nest that has been

removed

in the

USA

.

The researchers suspect that there are other nests.

Clearance work with protective suit, vacuum cleaner and foil - US researchers remove hornet's nest

On October 22, 2020, the nest was discovered on private property and reported to the authorities.

Just two days later, on October 24th, the

entomologists (insect researchers)

were able to remove

the nest and the

hornets

inside

.

A total of 98 workers are said to have been caught by the researchers: 85 during suction and 13 outside of the nest.

At around 5.30 in the morning, the "clearance work" began - in special suits, with a special suction device and a lot of foil.

The head entomologist Sven Spichiger reported the following about the action: "The

removal

went very smoothly, although our original plan had to be adjusted as the

nest was

more in a

tree

than in the ground."

Scientists remove nest of "bee killers" - and suck off 85 hornets

The

experts

wrapped the affected tree tightly with foil, leaving only one area open.

Unnecessary openings were closed with foam.

Then the

hornet teat was brought

into position.

After the animals had reacted only sporadically, the scientists began knocking on the tree and driving the

Asian giant

hornets

out of their nest.

A total of 85 animals were sucked off.

13 others were caught with nets.

After most of the animals left the tree and none could be sucked out, the

nest was

filled

with

carbon dioxide

to either stun or kill

any

remaining

hornets

.

Asian giant hornets caught in the USA - now they are to be used for research

Since these are seen as a

danger to the domestic bee populations

, this was a common means.

Because of this danger, the animal is also given the name

"bee killer"

.

At the end of the work, the last opening was also sealed with foam.

However, the tree is to be felled to check how big the nest was and whether individual animals have survived.

On the Facebook page of the

Ministry

of

Agriculture

, it is said that all 85 animals that were sucked out survived and that these are to be used for further investigations.

The WSDA also thanked the owners of the private property and generally those who

report

sightings of the

Asian giant hornet to

the ministry.

The Asian giant hornet: a threat to bees, other insects - and humans

The

Asian giant hornet (Vespa mandarinia)

is the largest hornet species in the world.

It

was first spotted

in the

United States

in December 2019.

But what makes the Asian giant hornet so special?

  • "Bee killer" or "killer hornet"?

    Asian giant

    hornets mainly attack honey bees

    .

    They decapitate the smaller animals and take over the nest of the wiped out bee colony.

    The offspring of the bees serve as food for the hornet offspring.

  • Attacks on people or pets

    do not take place for no reason, but only when the hornets feel threatened.

  • The

    poison of

    an Asian giant hornet is more poisonous than that of a honey bee, while the

    sting is

    larger and the hornet can

    sting

    multiple times.

  • Experts

    especially warn allergy sufferers

    not to get near Asian giant hornets.

  • Beekeepers who work with honey bees shouldn't

    trust

    their

    protective suits

    either

    .

    These offer no protection from the sting of the Asian giant hornet.

  • Nests or colonies

    should not and must not be removed without authorization.

    You should always consult a professional.

In

Germany

there is still

no confirmed sighting of

the Asian giant hornet, but the Asian hornet.

However, this is smaller and has little contact with people due to the lack of interest in human drinks or food.
