The Asian hornet is advancing: danger to humans and nature?

The Asian hornet (Vespa velutina) is an invasive exotic species that has become increasingly widespread in the Netherlands in recent years. Whereas this species of wasp was rare just a few years ago, reports are now coming in from almost all provinces. The advance is causing increasing concern, especially among beekeepers, nature managers and people who work or live outdoors.

How do you recognize the Asian hornbug?

The Asian hornet is slightly smaller than the European hornet, but often looks darker. Main characteristics:

• A black thorax

• Yellow ends of the legs

• One narrow orange band on abdomen

• Approximately 2 to 3 cm long

Because it often nests high up (think treetops, sheds or eaves), it is sometimes noticed late.

Why is this wasp such a problem?

The Asian hornet does not pose a great danger to humans as long as it does not feel threatened. However, there are two main reasons why we should take this species seriously:

1. Damage to biodiversity – The hornet actively preys on honeybees and other pollinating insects. This jeopardizes the balance of ecosystems.

2. Risk of aggression when disturbed – Anyone who accidentally disturbs a nest, such as during garden work or in nature, may face an aggressive reaction.

What can you do in case of suspicion?

Do you see a suspicious large wasp or a possible nest? If possible, take a clear picture and report your observation through waarneming.nl or the special hotlines for exotic species. Above all, do not try to control the animal or nest yourself.
