A riveting account of an extraordinary animal. Lester engages readers in the biological complexities and wide-ranging impacts of a “scary” wasp as an excellent example of controversies swirling around biological invasions.’ — Daniel Simberloff, Professor of Environmental Studies at the University of Tennessee and author of Invasive Species: What Everyone Needs to Know.

Wasp Wipeout 2019

Wasp Wipeout is now in its third season, with additional sites in the West Coast and Canterbury added to those in the Nelson Lakes, Marlborough and Tasman regions. This is a fantastic initiative between Stuff and Department of Conservation and adds significantly to the land area where Vespula wasps are being controlled.

The shipping regulations regarding all material classed as dangerous goods means it has become increasingly difficult to ship Vespex® to the North Island. This adds at least 24 hours to delivery times. In addition to this, we have begun to experience issues with some Courier Post drivers refusing to carry items classed as dangerous goods (DGs) to rural addresses, but we are unable to determine in advance which rural addresses might be affected. Even if a rural delivery service will take DGs, it will add an additional 24-48 hours to delivery times. The combined effect of this situation is that we cannot deliver Vespex® to any North Island address classed as rural by our courier service provider. If you know your home address is likely to be rural, please provide an alternative delivery address in town (e.g. a relative's house or a store you have a working relationship with). Alternatively, please contact us and we will provide the address of your nearest Fastway agent.
