@MichaelMulvaney, At ANBG's Section 187 there is a very active European Wasp nest in a hole in the ground, with a large number of wasps flying in and out. The nest is on the western side of the tarmac road, about 1m from the retaining wall and under the bush seen in the final image. The location has been marked with a stone on the retaining wall as seen in the final image. Can this nest be eradicated?
