Wasp populations are rising across Auckland and threatening to cause significant environmental and economic harm, experts say. Auckland Council biosecurity advisor Emma Edney-Browne said data indicated the "aggressive pests" had a growing presence in the region. The Wasp Tactical Group was formed in 2013 as a network of scientists and stakeholders who were concerned about wasps. Lester said the group was currently in the process of trialling a wide range of different methods of wasp control. Edney-Brown said Auckland Council was working with other parties and experts on research and development of improved wasp control tools.
