are is so right about the smell.
A very long story...last year we stayed in a cabin in my Dad's garden. We lived there for 8 months. During the Spring, some delightful wasps started to build a nest in the roof. They used insulation and spit! Bit by bit they started to come in side our cabin. At first it was just one or two, on this day, my DH killed one ...out of NOWHERE came another one and stung me very badly on the ankle!
We had no idea (at this time) that we had been sleeping within inches of a giant wasps nest above our bed!
So, one day we noticed a patch of mould on the ceiling. DH decided to clean it off... a MASSIVE mistake! The roof gave way and hundreds of them came flying in. My Brothers took to killing them that evening, the following day was carnage. There were wasps all over the cabin in various stages of death.
The Queen still lived on.
Next day my DAD decided to "get rid of the nest" with the aid of just a broom. I remember watching him poke away in just his shorts, and my sep-mums summer hat!
As the queen died. The rest of them gave up, or flew away.
I admired their work ethic, that nest took ages and was very beautiful.
Just not above my bed.
