Ants are social insects that often find their way into homes in search of food and shelter. While some ant species may be harmless, others can become a nuisance and cause damage to property. Identifying the common ant species invading your home is crucial for implementing effective eradication strategies. If you trust experts, finding solutions for pest control in Sydney can be easy. In this blog, we will explore the identification of some typical ant species found in homes and provide tips for eradicating them to maintain a pest-free living environment.

Argentine Ants (Linepithema humile)

Argentine ants are small, light to dark brown ants that form massive colonies. They are commonly found trailing along walls, countertops, and baseboards, especially during warmer months. These ants are attracted to sweet foods and can quickly become a nuisance in kitchens and pantries.

Eradication: Argentine ants are best dealt with through baiting. Using ant baits with slow-acting, non-repellent insecticides will allow the ants to carry the poison back to their nests, effectively eliminating the entire colony.

Carpenter Ants (Camponotus spp.)

Carpenter ants are larger ants with a black, red, or combination of black and red coloration. They do not eat wood but excavate galleries in it to create nests. They are often found near sources of moisture and can damage the structural integrity of wooden components in a home.

Eradication: To eliminate carpenter ants, it is essential to locate and destroy their nests. Applying insecticidal dust to their galleries or using non-repellent baits can help control the infestation. Additionally, removing sources of moisture around the house can discourage them from nesting.

Odorous House Ants (Tapinoma sessile)

Odorous house ants are small, dark brown ants that emit a strong, rotten-coconut-like odor when crushed. They are attracted to a wide range of food sources, including sweets, meats, and fruits. These ants often form trails along walls and floors in search of food.

Eradication: Baits are the most effective way to control odorous house ants. Place sweet or protein-based ant baits near their foraging trails. As these ants have multiple queens, it may take time to completely eradicate the colony.

Pharaoh Ants (Monomorium pharaonis)

Pharaoh ants are tiny, pale yellow ants that can be challenging to control due to their nesting habits. They prefer warm, humid environments and are often found nesting in wall voids, electrical outlets, and under flooring.

Eradication: Pharaoh ants should be treated with extreme caution, as improper control methods can cause their colonies to split, making the infestation worse. Professional pest control services are recommended for dealing with these ants.

Pavement Ants (Tetramorium caespitum)

Pavement ants are dark brown to black ants with pale-colored legs and antennae. They nest under pavement and can invade homes in search of food. These ants are commonly found near sidewalks, driveways, and the foundation of buildings.

Eradication: Applying residual insecticides around the perimeter of the house and near ant entry points can help control pavement ant infestations. Regularly cleaning up food spills and keeping the area around your home free of debris will make it less attractive to these ants.


Identifying the ant species invading your home is crucial for implementing targeted eradication strategies. Different ant species require different approaches to control effectively. While some ant infestations can be managed through DIY methods, others may require professional intervention. By understanding the behavior and habits of common ant species and employing the right eradication techniques, you can maintain a pest-free home and protect your property from potential damage caused by these tiny intruders. If in doubt or faced with a large infestation, it is always best to consult with a pest control professional for expert advice and assistance.
