Nests underground and in cavities in tress and buildings. Nests can be located by searching likely sites on fine days for signs of wasp activity. Flight lines of foraging wasps converging towards, or diverging away from nests may be observed in order to pin-point the nests. Workers are 3.4-5mm long, queens 15mm long. Workers are dark brown-black, queens mid-brown; waist of only one segment. An active insect, it nests outside in grass and walls and under paving. It will forage widely in search of food, which is how it comes to enter domestic premises. Insecticide treatments can be applied in and around the nest and should aim to ensure that a residual film of insecticide is maintained at strategic points, for example points of entry to buildings, such as doors, windows, ventilators, ducts & drains. Insecticidal baits, too, can be used around the entry points.
