German Wasp
Vespula germanica
- Group
- Social wasp
- Size
- 11–14 mm
- Risk
- High danger
- Protection status
- Not protected
- Identifying features
-
- Extremely similar to the common wasp
- Usually three black dots on the clypeus (rather than an anchor-shaped line)
- Nests in dark cavities, usually somewhat larger and greyer than that of the common wasp
The German wasp (Vespula germanica) is almost indistinguishable from the common wasp and is likewise one of the wasp species most often encountered at the table and on the terrace. In late summer it is strongly attracted to sweet foods and meat, and it defends its nest aggressively.
Identifying features
- Size: workers 11–14 mm
- Clypeus (face shield): usually three black dots, rather than the anchor-shaped line of the common wasp
- Nest: in dark cavities, usually somewhat larger and greyer than that of the common wasp
Risk
High: in late summer the German wasp is strongly attracted to sweet foods and meat and defends its nest aggressively. For sensitised individuals there is a high risk of allergic reactions, up to and including anaphylactic shock.
Protection status in Switzerland
Not protected by law (not listed in Annex 3 of the NHV, the Swiss Nature and Heritage Protection Ordinance), Red List status “least concern” (LC). Control measures are permitted where human health is at risk.
What should you do about a nest?
Because the German wasp is barely distinguishable from the common wasp and both species defend their nests aggressively, we advise against treating a nest yourself in living areas. We are happy to advise you on the safest approach for your situation.
