Don't spread ants

Apart from the natural radial expansion of existing colonies, big-headed ants are spread unintentionally through transport by people via a wide range of commodities, including soil, pot plants, foodstuff and rubbish. Several plant nurseries in metropolitan and country areas are infested with big-headed ants and present a risk of spread. Be sure to check that pot plants or any other plant material you may receive, even from friends, are free of ants.

If you are moving house and take pot plants with you, or are giving pot plants to friends, check that the pots are free of ants or treat the pots by immersing the pot for 30 seconds in a solution of an insecticide registered for controling ants.
