Report a nest

On this page

Currently, summer nests of the Asian hornet are being observed, both close to the ground and at high altitudes (up to 30 meters or more). These nests can reach a size of 1 meter in the autumn. Never attempt to handle an Asian hornet nest yourself; always contact a professionally recognized eradicator!

Contact the fire brigade or a private eradicator in case of immediate danger, for example, when the nest is near a residence or another high-risk location.

What happens with my report?

  • You will receive a list of recognized Asian hornet eradicators in Flanders immediately after reporting.
  • We validate your report, which may take a few days.
  • We will notify you if it is indeed an Asian hornet nest.

Is eradication free of charge?

Currently, there is no coordinated Asian hornet eradication, so we do not automatically assign an eradicator for an Asian hornet nest. The government currently does not reimburse eradication costs.

Exceptions to this general rule are:

  • In West Flanders, nests of the Asian hornet will no longer be removed for free from 10 November 2023. This means that all non-validated reported nests still open on 10 November 2023 will no longer be eradicated by the province of West Flanders. You can either hire a private exterminator yourself if you want to have this nest removed.
  • In East Flanders, coordinated eradication of nests stopped on 10 November 2023. As many nests as possible reported before 6 November 2023 were still eradicated. You can find more details here for East Flanders here. You can either hire a private exterminator yourself if you want to have this nest removed.
  • In Flemish Brabant, certain municipalities have their own programs: Begijnendijk, Tremelo, Keerbergen, Boortmeerbeek, Leuven, Holsbeek, Zoutleeuw, Landen and Bierbeek. More information can be found on the websites of these municipalities.

Report a nest

It is important to submit a photo in which the wasp is clearly visible. Different species of wasps build the same type of nest this time of year. A clear photo of the wasp is needed to determine the species.
