Argentine ants Linepithema humile (Mayr) are one of the world's most invasive and problematic ant species. They are very aggressive, and although they are not poisonous, they do bite people.
Unlike other ant species, Argentine ant colonies cooperate with each other, and can combine over winter into super-colonies. They reach enormous numbers, which means they have a huge appetite. It also makes them more aggressive towards other insect populations through their sheer numbers.
Learn about Argentine ant super-colonies and other facts about this pest species that is spreading in New Zealand.
Argentine ants eliminate native ants, compete with kiwi and other native species for food, and displace and kill New Zealand's native invertebrates.
