How to tell the difference between ant species in Australia

How to tell the difference between ant species in Australia

HOW TO TELL THE DIFFERENCE BETWEEN ANT SPECIES IN AUSTRALIA

 

There are at least 1,275 known species of ants in Australia, but only a few are considered as household pests. It’s handy to know which species you’re dealing with in the event of an outbreak, as this can affect the type of treatment you’ll need to manage them for good.

If you’re experiencing an ant outbreak and wondering which type of ant is the cause, we’ve prepared this guide on identifying the most common pest ants.

What questions will this article answer?

Why is it important to identify ant species?

While most ant outbreaks can be easily treated, certain types of ants require more targeted or aggressive solutions as they behave differently.

For example, some ant species like Pharoah and Argentine ants can multiply fast andcreate several nests, so they require long-term treatment to prevent sustained attacks. On the other hand, bull ants are known for their painful bites and carpenter ants build their nests in wooden house frames, so you’ll want to prevente an outbreak fast.

However, without special training, it can certainly be challenging to try and identify which species of ant is causing problems around your home or business.

The earlier you figure out which species of ant is the culprit, the faster that the outbreak can be treated, and any potential damage and disruption can be minimised. That’s where professional pest control can make a big difference.

Black House Ant

Quite possibly the most common type of ant that you’ll encounter, black house ants often lurk around kitchens, bathrooms and even your garage.

They are 2.5-3mm long and shiny black coloured, with 6 spindly legs.

Black house ant larvae normally take over 6 weeks to mature into adults.

They feed on sweet and greasy food, breadcrumbs and meat.

Fire Ant

As aggressive defenders of their nests, fire ants aren’t afraid to sting to defend their colony if provoked. These painful stings can swell into welts within 24-48 hours and trigger allergic reactions.

They build distinct nest mounds which can stand over 40cm high above their underground chambers.

Fire ants have a characteristic antennae club, bright copper head and dark brown body. Workers grow between 3.18-6.15mm and queens are 1.59cm long.

Larvae take 16 days to mature.

They feast on dead insects, vertebrates and earthworms, as well as sweets, fatty food and proteins.

Ghost Ant

Drawn to areas with high moisture, such as kitchen and bathrooms, ghost ants nest in wall spaces, loose bark, flowerpots and underneath objects in the ground. A single colony can have several nesting sites.

They have pale, translucent legs and abdomens and grow up to 1.6mm long.

Ghost ants eat sweet and greasy food, as well as honeydew produced from aphids.

Odorous House Ant

Producing a unique coconut smell when crushed, odorous house ants are attracted to places with moisture. However, you’ll also find them lurking around house plants and toilet lids.

They are usually brown or black in colour with 6 legs and antennae with 12 segments.

Odorous house ants grow between 1.59-3.18mm long and take 34-38 days to become adults.

They feed on pet food, sweet foods and fruits, particularly melon.

Pharoah’s Ant

Most commonly found in heating systems and areas with humidity, Pharoah’s ants swarm all year long and are often found in hospitals. They form new colonies after their nests have been disturbed from insecticide treatments.

Pharoah’s ants have black eyes and 2 small segments at the pedicel. Workers are yellow/brown with brown abdomen and grow up to 1.5-2mm long. Males have wings and are usually black and 3mm long. Queens are dark red and also have wings, and typically measure 3.5-6mm long.

Larvae take 18-20 days to mature into adults.

Their favourite foods are high in protein, such as meat, blood, fat and dead insects.

Carpenter Ant

With their strong jaws, carpenter ants chew through wooden structures and objects, leaving behind wood shavings, also known as frass. They can cause significant structural damage to buildings and trees, and build satellite nests in different areas.

Carpenter ants are usually dark brown, orange or black coloured, with 6 legs and 2 antennae. They range from 3-12mm long, depending on their job classification within the colony.

Workers take 60 days to become adults.

They enjoy feeding on honeydew produced by aphids, dead insects and pantry food items.

Argentine Ant

A well-known ecological pest, Argentine ants are aggressive and territorial, and will deter other native ant species from setting up a colony in their preferred area. They also attack nesting birds and hatching eggs. You’ll find their nests in wood, tree cavities, older shrubs and mulch.

Argentine ants are light to bark brown in colour, with a small and slender build. They grow 2.2-2.6mm long.

Their diet includes sweets, decaying fruit, cereal, meat products as well as insects.

Bull Ant

If you’ve disturbed a bull ant nest, watch out! They can be very aggressive and secrete venom through their painful bites. With excellent eyesight, they prefer to hide away in areas with dense vegetation, nesting under logs and rocks.

They are red to black coloured and can grow up to 40mm in size. Eggs take 3-4 months hatch and mature into adults.

They collect plant nectar and other plant juices as well as animal prey.

Professional ant extermination

Before initiating treatment, our expert pest control technician will thoroughly assess the outbreak and identify the type of ant or ants involved. We’ll locate the ant nests as well as potential food sources that need to be removed.

Then, we’ll come up with a treatment plan, which typically involves a combination of the following methods:

Ant control dust

When sprinkled into wall cavities and roof voids and other hard-to-reach areas, this kills ants upon contact.

Insecticide

Applied to treated zones around the perimeter of the building, this acts as an effective deterrent for ants attempting to enter.

Chemical baits

We’ll strategically position baiting stations at popular feeding sites to ensure that as many ants as possible can carry the poisonous bait back to the colony.

Ant prevention treatment can usually take time before seeing results, so your technician will need to return to replenish it and review its effectiveness after a few weeks.
