Its getting late on for wasps and there a still a load going about. We are finding the nests are of a fair size. Round about this time they are producing Queens for next year. So allowing a nest to end isn't really the best option. Once the main colony dies out the Queens will either go into hibernation or they will move to another location amd hibernate. Culling a nest as early as possible during the season is the best option. If you see a nest give is a call ASAP. 01333 771000
