DOC information on wasps

The Department of Conservation (DoC) also provides very good information around wasp identification and control.

"New Zealand has several kinds of native wasps which have evolved here and have never become a nuisance.
But five social species of wasps have been accidentally introduced since the 1940s and are classed as pests (German and common wasps, and three species of paper wasp).
How to identify wasps
Introduced wasps are a significant pest which harm our native birds and insects, and are a threat to human health and recreation."
