Sitting down, minding my own business when a sodding big wasp buzzes in. On the basis all doors and windows are shut, I suspect it's found a way in from the loft - probably through the weird slatted wooden ceiling[1] we inherited over the breakfast area. It's insulated above, but there is a path to the loft through it.
So I take it any wasps in my loft haven't died off :(
