Germany warns of invasive ant and Asian hornet damaging homes and ecosystems

The large glandular ant (Tapinoma magnum), an invasive species first recorded in Germany in 2009, is spreading from the Mediterranean via imported plants. It builds extensive underground nests that can undermine foundations, damage graves, walls and electrical installations, and interfere with internet cables. The Umweltbundesamt and the Federal Agency for Nature Conservation label it a potentially invasive species and advise that, while it poses no direct health risk, it can cause significant property damage and displacement of native ants.

The Asian hornet (Vespa velutina) was first detected in Germany in 2014 and has since expanded across several states, including Baden‑Württemberg, Hessen and North Rhine‑Westphalia. Classified as an invasive species by the EU, it preys on honeybees, wild bees and other insects, threatening biodiversity and causing crop losses by feeding on grapes and other fruits. Although its sting is not more dangerous than that of the native European hornet, allergic reactions can occur. Authorities stress that nests should not be removed by amateurs; sightings must be reported to state environmental agencies, which coordinate control measures.
