No immediate danger
A hornet feeding on flowers or hunting is not looking for contact. Check the species: many sightings turn out to be European hornets or wasps.
2026 season · the reference platform
Collective action against the Asian hornet, town by town
LeFrelon connects the residents who report hornets, the organisations that lead the control effort in their area and the companies that remove the nests. A non-profit platform, free for local authorities.

Lightest shade: no nest reported on LeFrelon, often because the department is not organised on the platform yet. It does not mean there are no hornets.

Take action
Have you just seen an Asian hornet?
Three situations, three things to do. Whatever happens, never try to destroy a nest yourself.
Stay more than 5 metres away
Do not mow or trim nearby. Keep children and pets away, then report the nest: the local team will take it from there.
Several stings: call 15 (or 112)
A sting in the mouth or throat, a swollen face, difficulty breathing, feeling faint: these signs cannot wait. For a single sting, disinfect and keep an eye on it.
Control calendar
In October, nests finally become visible
As the leaves fall, secondary nests appear at the top of trees. They are still active and producing future queens: removal remains worthwhile as long as the colony is there.
A nest that is empty in winter is never reoccupied. There is no point having it removed after the first frosts.

Is the Asian hornet dangerous?
The risk comes from the nest and from allergy: the Anses data, without exaggeration.

The platform
A shared tool to organise the control effort across an area
Local authorities, beekeepers' health groups (GDSA), FREDON plant-health bodies and pest control companies work on the same reports, each with their own rights, from the first call to the end-of-season review.
