History and Background
The German Wasp (Vespula germanica) was first recorded in New Zealand in the 1940s. Native to Europe, it has since spread rapidly due to favorable conditions, particularly in beech forests. It is one of the most aggressive wasp species in the country.

Distinct black and yellow bands on the abdomen.
No visible hair on the body, unlike bees.
Where Are They Found?

- Commonly found near human settlements where food sources are available.
- Nests are often underground or inside walls, roofs, and tree hollows.
Why Is It a Problem?
- Extremely aggressive, especially when disturbed.
- Competes with native species for food and disrupts ecosystems.
- Can cause painful stings, leading to allergic reactions in some individuals.
- Known to invade outdoor eating areas and scavenge for sugary foods.
