I am petrified of wasps but manage to stay generally FAIRLY calm nowadays.
Literally the worst day of my entire life was at university when we had a wasps nest in our porch. We got the council to come out and deal with it, they gassed them and, it being a Friday, we all disappeared home for the weekend.
When I returned, I calmly entered my housemate’s bedroom, at the front, above the porch, to be confronted with an entire room covered from carpet to bed full of mostly dead, some slightly pulsating wasps like something out of a horror movie. To this day I don’t know how I dealt with it. Well I do...I ran out screaming and waited across the road til a more sensible housemate arrived and could deal with it. For months he would wake up and find a dozy wasp or two next to him on the pillow...
