Oak processionary moth triggers public safety measures in German towns

The municipalities of Körle and Melsungen in Germany have reported new infestations of the oak processionary moth (Eichenprozessionsspinner). Health officials warn that the caterpillars' fine hairs can cause skin irritation, intense itching, eye inflammation and respiratory problems, particularly affecting children, allergy sufferers and people with pre‑existing respiratory conditions.

Körle has cordoned off affected areas such as a nature playground, an adjacent oak stand and public pathways, posted warning signs and arranged for a specialist firm to remove nests, prioritising high‑traffic sites like kindergartens, sports facilities and sidewalks. Residents are asked not to touch the nests and to report sightings via phone or email.

Melsungen likewise conducts regular inspections, informs the public, blocks dangerous zones and employs mechanical removal and the placement of bird (meisen) boxes as a preventive measure. The city stresses that private property infestations should only be tackled by qualified professionals.

Both towns request citizen assistance in reporting suspected nests, providing details such as location, date, tree type and whether the sighting involves caterpillars or nests.
