There are many different species of ants in NSW. The common black house ant, the small eastern brown ant, green ant and carpenter ant. These species pose the biggest problem in our area. The common black ant is the most complained about. The eastern brown is very small and will excavate large amounts of dirt around houses. But the green ant has small nests and will inflict painful bites. Ant treatment and control will depend on species. Best forms of treatment come in gel and liquid forms; ant stations and granules for colony control.
