Introduced wasps are a significant pest which harm our native birds and insects, and are a threat to human health and recreation.
To help control wasp populations, Nelson-based company Merchento have developed a wasp bait in conjunction with DOC. Vespex was piloted on five public conservation land sites in 2015, and reduced wasp activity by more than 95%.
The protein bait, which contains the commonly used insecticide fipronil, is targeted at wasps and is not attractive to bees.
