European Wasps at the entrance to their underground burrow.
I normally adopt a laissez-faire policy to whatever comes to my garden, but this was unacceptable! A group of these had attacked and hospitalised my elderly neighbour in the past.
Under cover of night, swathed from top to toe, and carrying a torch (flashlight) filtered with red cellophane, I dealt the death blow: a full container of wasp powder
straight down the entrance hole.
