Invasive ant species detected in Germany spur control and health warnings

The large glandular ant Tapinoma magnum, known as the “große Drüsenameise,” was confirmed near the railway station and surrounding areas of Haßfurt in Bavaria. The city has begun eradication efforts, warning residents not to use large amounts of commercial insecticide or to burn nests because of fire risk. The species, native to the Mediterranean, likely arrived via imported ornamental plants and can form extensive “supercolonies” that displace native ants.

In Baden‑Württemberg, researchers have identified the Asian needle ant Brachyponera chinensis, an invasive species whose sting can cause severe allergic reactions similar to wasp stings. The EU classified the ant in 2025 as a high‑risk organism, citing its potential health hazards. The discovery highlights growing concerns over invasive insects that threaten both ecosystems and public safety across Germany.
