heard before seen, loud continuous buzzing I recognized as a wasp, probably a queen, which it was. It appeared to be about 2cm long when flying and when crawling on window. image 1 is after being killed by rapid effective fly swat.
This house has attracted many queen vespula wasps over the last 25 years. There used to be several a year, some trying to get into the house past netting screens. They and non-queens have also come down the light fittings into the room in the evenings.
I have been told the house surroundings are ideal for wasps. Large native and exotic trees, with natural ground litter of fallen branches, twigs, leaves etc. No chemicals.
