Oak Processionary Moth Outbreak Forces School and Pool Closures Across Germany

A massive outbreak of the oak processionary moth (Eichenprozessionsspinner) is disrupting public facilities in several German cities. In Bremen-Osterholz, a primary school has been closed to in‑person teaching since June 18 because the entire campus is littered with moth nests; only emergency care is provided and parents complain about unpredictable reopening dates. The city reports a four‑fold increase in sightings this year, with about 4,400 nests recorded so far.

In Bad Waldsee, authorities have identified roughly 120 nests and are treating them with a specialised adhesive spray. The city aims to finish work by June 26, noting that the current infestation is about ten times higher than in previous years.

Detmold temporarily shut two public swimming pools after moth hairs – fine, toxic setae that can cause skin irritation, allergic reactions and respiratory distress – were found on the premises. Both pools reopened after specialist pest‑control teams removed the nests. The municipal spokesperson said, “Wir hätten lieber andere Neuigkeiten für euch, aber wir dürfen euch dieser Gefahr nicht aussetzen.”

Across the affected regions, officials are prioritising schools, kindergartens, playgrounds and recreational facilities for nest removal, citing the health risks especially for children, the elderly and allergic individuals.
