Let's Talk About Ants

Ants come in different shapes and sizes with different species enjoying different diets, living quarters and habits. This means when it comes to pest control treatments - it is not a one size fit all.

We thought we’d travel down the ant nest and tell you about the main 3 ants that you’d see around your Aussie home; black household ants, coastal browns and green ants.

Black Household Ants

This ant is considered more of a nuisance than a destructive pest, and with more than one queen in the colony they reproduce fast. 

These busy, tiny ants have a preference for sugary liquids, loving honey and sugar and will generally enter the home in search of food. They are a pest of domestic environments and build their underground  nest in cracks or gaps, such as beside pathways. You’ll notice these ants navigating to and from their nest in trails. 

The black household ants will fixate on things until they are full (ever found ants infesting your tissue box and then disappear?) and will also not eat at all when relocating their nest. These behaviours mean it can be harder to convince them to take bait and because they are experts at creating nests in difficult to spot cracks, they make colony elimination tricky. 

Coastal Browns

These ants are also known as big headed ants and will sting when under threat, however, good news is, their sting is not painful for humans. They are protein eaters and will forage for fat and oil based foods, even other insects. 

They are an invasive species that often has multiple queens in a single colony and create what we call ‘super-colonies’. As a colony grows, ‘budding’ takes place where a queen and workers will establish a new colony in close proximity. 

They are a soil-nesting ant that removes soil into mounds near their nest opening, so although easy enough to find, the expansiveness of their colonies - that sometimes stretch beyond property boundaries - can make exterminating harder.

Green Ants

Green ants are well known for their painful sting. They are soil dwellers and their nests can also be found under rocks, in lawns and logs.

They are bigger so spread slower than black household ants and coastal browns and are more particular with their food. These scavengers hunt for proteins and oils, smaller insects and are more organic eaters going for grass seeds and nectar. 


It is important to identify which type of ant/s you have around your home before treatment. This allows us to achieve the best ant control possible and (depending on the population) can control any ant colonies at your property within 10 days. The team at CDI Pest Management have a thorough understanding of different species of ants and their behavior patterns, so if you have ants that you want treated around your home, call us today.
