Honey company Comvita has joined efforts to cull the numbers of wasps across the country. Introduced German and common wasps are a damaging pest, invading beehives and eating insects – reducing the amount of food for native birds. A Department of Conservation programme, Wasp Wipeout, raises funds for bait stations used to control populations. Comvita Head of industry affairs Tony Wright says increasing numbers of wasps and the damage done to their hives has got the company involved.
