I have just been down to the recycling banks by the river bridge at Dunbeath to recycle bottles and jars, I did the green bottles into the end bin and started to put the white bottles into the centre one when I found myself surrounded by very angry wasps.
I beat a hasty retreat up the road screaming like a girl, (hope no one saw me) and waited at a safe distance before collecting my glass bin and scarpering.
I am not sure if they have nested in the bottle bank or they found a jam jar that hadn't been cleaned out properly, but I will finish emptying mine in town tomorrow.
