This piece of folk wisdom has been around for a very long time. If the winter has been fierce and cold, the summer that follows will be mercifully free of wasps. But is there any scientific backing to this claim? If not, where did this myth originate?
The shortest possible answer is ‘no, wasps won’t be affected by the unusually cold winter’. The reason why, though, is a bit more complex, and it requires some understanding of wasp social structure.
