Overview
- Regional reports published Wednesday show the invasive marmorated stink bug is now widespread in parts of Germany, with especially dense records in the mittlerer Neckarraum, Rheingraben and Bodenseeregion.
- With cooler days the adults are entering buildings to overwinter, sheltering in attics, cellars and wall crevices and becoming a common indoor nuisance that emits an unpleasant odor when disturbed.
- The species feeds on more than 300 plant types and causes sunk spots, discoloration, internal fruit damage and premature fruit drop, a pattern farmers warn can lead to serious yield losses and large economic harm.
- Residents are advised not to touch the insects, to trap them with a glass and card and to photograph and report sightings to platforms such as iNaturalist or Naturgucker to help monitoring and mapping.
- Control in Europe relies mainly on pesticides and physical barriers with limited success while researchers study biological options like native parasitoid wasps that curb the bug in its East Asian range.
