The Asian hornet has been present in our country for several years. This exotic insect species poses a threat to native bees and other insects. Therefore, it is important that you recognize this hornet and know what to do if you see one.

Why is the Asian hornet a problem?

The Asian hornet (Vespa velutina) does not occur naturally in the Netherlands or the rest of Europe. This hornet poses a threat to native bees and other insects. The Asian hornet eats bees, bumblebees, and other insects. This has a negative impact on biodiversity and crop pollination. When the Asian hornet feels threatened, it can sting people. A sting from the Asian hornet is slightly more painful and causes more burning than a normal wasp sting.

How can you recognize the Asian hornet?

Recognizing the Asian hornet is important in order to take quick action. They are generally larger than native bees and wasps. Here are a few characteristics to look out for:

  • Size: The queen can grow up to 3.5 cm in size. The workers are between 2 and 3 cm long.
  • Color: They are dark, almost black in color with a yellow or orange band on their abdomen.
  • Face: The face of the Asian hornet is orange-colored, with black outlines around the eyes.

See if you can find the spring nest of the Asian hornets.

  • Is the nest on your own property? Then report it via waarneming.nl. The province's pest control officer will then take action.
  • Have you spotted a nest on municipal land? Report it in our BuitenBeter app.

Hornet sighted from July through September

It is likely a worker bee. Observe the direction in which the worker bee flies away and mark the direction on a map of the location. Then report it via waarneming.nl.

Do you see more workers? Mark their flight direction on the map and report it via waarneming.nl. This will help to locate the nest.
