We tend to associate wasps with hot summer days ruining our lovely picnic, but while wasps are more prevalent in summer, it's this time of year that they can become aggressive.
As they begin their preparation for winter hibernation, so the wasp nest slowly begins to die off and stops producing worker wasps.
The remaining workers feel disoriented by the change and no longer have the abundance of food they had at the height or summer.
This makes them a little desperate for nutrients so they look for anything sweet which often brings them to our fizzy drinks and jam sandwiches.
Fermenting fruit is a big draw too, and that can make them a little lightheaded!
It’s best to remain calm and let them be if you can. Wasps are a really important pollinator doing a vital job for us, and we appreciate them for the ecological marvels that they are!!
