Oak Processionary Moth Outbreak Triggers Broad Control Measures in Bavaria and Coburg

Germany is confronting a severe outbreak of the oak processionary moth (Eichenprozessionsspinner) that has spread from its first sightings in Coburg in 2010 to cover the entire city and multiple highway sections in Upper Franconia. The insect’s larvae develop urticating hairs that can cause skin irritation, respiratory problems and, in serious cases, asthma attacks.

Coburg’s green‑space department is using a specially equipped vacuum to suction larvae and nests from public trees, a method that captures all developmental stages while minimising the risk of spreading the hairs. Private property owners are instructed to avoid contact with infested trees and to report sightings to the city office.

Along the A73, A70, A93 and A9 motorways, the Autobahn GmbH of the federal road authority has engaged a specialist firm to remove nests without chemical sprays, prioritising rest‑areas, parking zones and gas stations. Workers wear protective gear, and the operation is scheduled to finish by the end of July 2026, with traffic expected to remain largely unaffected.
