Redback spiders have established populations in Central Otago and Taranaki, posing a threat to human health and taonga native species such as the critically endangered Cromwell chafer beetle.
We talk to Chemist Dr Andrew Twidle, who is leading the development of a pheromone tool to eradicate these invasive redback spiders, the first attempt in the world to control pest spiders using pheromones. The project is supported by Lincoln University, local iwi, and the Department of Conservation.
