Overview
- Stadt Hof has cordoned an area at Untreusee and hired specialists to remove nests after confirming oak processionary moth presence, and officials warn people to avoid the marked zone because the caterpillars’ hairs can cause skin, eye and breathing problems.
- Brandenburg authorities have closed roughly half of the waterways in the Unterspreewald to boat traffic while they assess and treat heavily infested trees, and officials say how long the bans last will depend on how the infestation evolves.
- Denmark is reporting a wider spread of the species beyond Odense, with nests found recently in Copenhagen, stoking pressure on national agencies to scale up spraying and removal and prompting contested proposals such as mass felling of oak trees.
- Standard control work uses a specialist adhesive spray to bind the caterpillars’ urticating hairs before workers in protective suits remove and dispose of nests, and local teams say repeated treatments may be needed through the season.
- The outbreak is disrupting recreation, tourism and routine maintenance near waterways, raising hard choices between immediate public health protection and long-term ecological trade-offs such as removing oaks versus relying on targeted treatments and natural predators.
