Vespa velutina, commonly known as the Asian hornet, has rapidly colonized territories beyond its native Asia. Its presence poses a significant threat to local ecosystems, particularly to honey bees, which are already vulnerable due to intensive pesticide use. This asymmetric warfare between the invasive hornet and native species has disrupted the delicate balance of biodiversity.
Key characteristics of the Asian hornet include :
- Size : 2 to 3 cm in length
- Color : Black body with a broad orange band on the abdomen
- Legs : Yellow at the extremities
- Nest : Pear-shaped, can reach up to 1 meter in diameter
Contrary to popular belief, the Asian hornet is not more dangerous to humans than a wasp or European hornet. Its sting typically causes a mild local reaction. However, allergic or immunocompromised individuals face a higher risk of complications.
The dangers of crushing an asian hornet
While it may be tempting to squash an Asian hornet upon sight, this action can prove counterproductive and hazardous. Here are the primary reasons to avoid this practice :
- Chemical communication : When crushed, a hornet releases an alarm pheromone, alerting its colony to imminent danger.
- Mass attack : Asian hornets exhibit highly communal behavior. Once alerted, they may attack in groups to defend their territory, significantly increasing the risk to humans.
- Long-term ineffectiveness : Killing an isolated hornet has no impact on the colony and may exacerbate the situation by provoking an aggressive response from other hornets.
The following table illustrates the chain of events triggered by crushing a hornet :
Action | Consequence |
---|---|
Killing a hornet | Release of alarm pheromones |
Alarm pheromones | Colony alert |
Colony alert | Risk of mass attack |
Responsible management of asian hornet nests
When confronted with an Asian hornet nest, it’s crucial to adopt a responsible and secure approach. Follow these steps to ensure safety :
1. Maintain distance : Hornets can detect presence several meters away and may become aggressive if they feel threatened.
2. Seek professional help : Contact a specialist in hornet nest removal. These experts possess the necessary equipment and skills to intervene safely.
3. Alert authorities : If the nest is located near a school, hospital, or public area, notify the local municipality. Firefighters will be mobilized to manage the situation.
It’s essential to note that only active nests situated within 10 meters of living or leisure areas can be destroyed, and this should only be done during the summer months. In winter, nests are generally empty and no longer pose an immediate threat.
Towards a balanced coexistence
Although the Asian hornet is an invasive species, its total eradication seems unrealistic. Therefore, it’s necessary to adopt a sustainable management approach. Research is ongoing to develop biological control methods, including the use of natural predators or parasites specific to the Asian hornet.
In the meantime, public awareness and the implementation of adapted intervention protocols remain the best weapons to limit this species’ impact on our ecosystems. Preserving biodiversity requires thoughtful and balanced management of all species, even those considered undesirable.
As we navigate this digital battleground of information and misinformation about invasive species, it’s crucial to rely on scientific data and expert advice. The development of an integrated detection framework could help in early identification and management of Asian hornet populations.
In dealing with the Asian hornet, caution and respect are paramount. By better understanding this insect, we can learn to coexist with its presence while protecting our bees and environment. This approach not only ensures our safety but also maintains the delicate balance of our ecosystem.
I’m still going to crush them when I see them
The worst of this article isn’t what it’s about, it’s the inappropriate ads Google puts here, which are not only repeated throughout the article, but all come back once opening the article again.

It’s really stupid not to continue to eliminate any foreign insect that could Wipeout a valuable insect as a honey bee.
Nope taking no chances. Will squash on sight or flame throw with hair spray
I understood from news reports that authorities are keen to be notified of any nests, and they will try to destroy any nests identified quickly,, to protect the native species.
Very helpful article. As a beekeeper one dreads thi invasion
Made in China
They are not ‘invasive’. Climate change has simply provided them with new environmental opportunities in which to thrive.
A bit stange at fiest says not a problem to humans but if less than 10 metres or near schools contact authorities to destroy nest
Nothing useful about these insects, unlike bees. We must protect the bees; so eradication is the only step. Besides, there are plentiful of them in the Middle East; they are not under threat.
It’s still better to crush than to not. Of people kill 400,000 a season. It DOES make an impact
If you’re unaware killing any bee alerts the colony. You definitely should take this advice in article with a grain of salt. I’ve killed these before with others around
I’ve been near the nest and no swarming occured so far.
Somewhat a stupid article. They should always be eliminated. Get in touch with your State agriculture department when found. They will attempt to find any colony(s) and destroy them. It doesn’t take long for a colony of these wasps to decimate an apiary. As a beekeeper I hope to never see one.
I have caught several asian hornets using a glass, like you would a bee. I put the hornet, contained in the glass into the freezer for several minutes. This induces a hibernation state allowing me to attach a long strand of high tensile wire to their body just above the abdomen. When the animal warms and comes back around, I coax it up my chimney where I tie the end of the wire to my fire grate. Once I have enough of them, at my command they will fly upwards creating enough lift as one unit to pull my house free from its foundations. I will then guide them, pulling my house and my belongings to a remote mountain and bring my house to rest next to a beautiful waterfall. Here I will release them from their burden and live out my days in peace and serenity, safe in the knowledge that I have done my part in removing a significant number of these hornets from the UK environment.
Soooo…where do they go in the winter? Do they repopulate nests in the spring? What’s wrong with destroying an empty nest? This article left too many questions.
I have seen a few in shoreham near the houses with the water mill…..10th october 2024
