What you can do
Control of these insects is only required when they are entering or living in building structures. The first approach should be to seal up any entry points in the building to precent ants gaining access to the property. If problems persist, a band of insecticide may be applied to harbourages and at entrances to buildings - windows, doors and vents. Make sure that sugary foods are kept in sealed containers and all food spillages are cleaned up as quickly as possible.
