After the first sighting in 2017, the number of discoveries of the alien species has increased markedly in our country in 2022. The Asian hornet continues to expand in French-speaking Switzerland and in the northwest from Switzerland. To protect native entomofauna and honey bee colonies, it is very important to quickly destroy as many nests of this invasive species as possible. The Bee Health Service (SSA) invites the public to report any sightings via www.frelonasiatique.ch.
