Germany battles oak processionary moth outbreak in Berlin and Hasselroth

Berlin's twelve districts have asked the city senate to treat the oak processionary moth as a health threat, not merely a plant‑protection issue. They cite widespread infestations in parks such as Hasenheide, Volkspark Wuhlheide, Siemensstadt, Schönhausen Park and Jungfernheide, and note that three sports facilities were closed because of heavy moth presence. The districts estimate over €500,000 in costs for 2026 and request coordinated, city‑wide control measures.

In the Hesse municipality of Hasselroth, officials report increasing sightings of the moth and urge residents to avoid contact with nests, especially around playgrounds and popular walking areas. Nests are being removed by suction or treated chemically, and temporary bans on benches have been imposed in high‑risk spots. Health officials warn that the caterpillar’s tiny hairs can cause severe skin irritation, eye inflammation and respiratory problems, especially as warmer, drier weather fuels the moth’s expansion.
