Asian hornet in Poland. Its nest has been removed, but it may return

The Asian yellow-legged hornet, an invasive species, was first detected in Poland in October 2026 near Krakow. The Ministry of Climate and Environment warns that some young queens may have left the nest and begun hibernation, potentially leading to an increase in their population in spring. This species poses a threat to native pollinators, particularly honeybees, disrupting local ecosystems. Immediate reporting of sightings or nests to local authorities is advised, along with photographic evidence. The yellow-legged hornet is not more aggressive than the native European hornet, but caution is advised for those allergic to insect stings. Its lifecycle resembles that of European hornets, with queens hibernating and building nests in spring.
