Ant control succeeds or fails on identification. Carpenter ants hollow out damp structural timber, fire ants build stinging mounds across a lawn, and sugar ants simply trail to food — and each responds to a different treatment.

This is also the pest where spraying visible workers does the most harm. Killing foragers without reaching the colony causes some species to fragment into multiple satellite colonies, leaving you with a larger problem than you started with.

Identifying the Species You Have

Carpenter ants

Large, usually black, and the only common ants that damage structures. They excavate galleries in damp wood rather than eating it, leaving coarse sawdust-like shavings. Their presence almost always signals a moisture problem that needs fixing alongside treatment.

Odorous house ants

Small brown ants that give off a distinctly sweet, rotten-coconut smell when crushed. They form very large colonies with multiple queens, which is why retail sprays tend to make them split and spread.

Pavement ants

Nest under slabs, driveways and walkways, pushing small piles of soil up through cracks. Typically move indoors in spring looking for food.

Fire ants

Build dome-shaped mounds in open sun and swarm aggressively when disturbed, delivering a burning sting. A genuine medical concern for allergic individuals, children and pets.

Argentine ants

Form supercolonies spanning entire neighbourhoods, following irrigation and moisture toward buildings. Because the colony is so large and interconnected, spot treatment reliably fails.

How Professionals Treat Ants

Baiting

Slow-acting bait is carried back to the colony and shared, killing the queen and brood. It is the only approach that reliably eliminates rather than suppresses, and it deliberately works slowly — bait that kills too fast never reaches the nest.

Non-repellent perimeter treatment

Modern non-repellent products cannot be detected by ants, so they walk through and transfer the active ingredient to nestmates. Repellent products, by contrast, simply push colonies elsewhere in the structure.

Direct nest treatment

Where the nest is located — a wall void, a fire ant mound, a stump — treating it directly is fastest. This is where correct identification pays for itself.

Moisture correction

For carpenter ants especially, treatment without fixing the leak or ventilation issue that created the damp wood will only postpone the problem.

What ant treatment costs

$150–$500

for a treatment programme

What moves the price:

Species — fire ant yard treatment and carpenter ant work cost more than sugar ants
Whether the nest is accessible or inside a wall void
Property and lawn size for perimeter or mound treatment
Whether recurring service is needed to prevent re-establishment

These are typical national ranges, not quotes. Pricing depends on your property and the severity of the problem.

What DIY Can and Cannot Do

Retail bait stations genuinely work on small sugar-ant trails, provided you resist spraying the trail at the same time — the ants must survive long enough to carry bait home.

DIY reliably fails on carpenter ants, fire ants and Argentine ants. The first requires locating a nest inside the structure, the second demands whole-lawn treatment for safety, and the third involves colonies far too large for retail products to touch.

Common questions

How much does an ant exterminator cost?

Typically $150–$500 depending on species and property size. Sugar ants sit at the lower end; fire ant lawn treatment and carpenter ant work involving structural access sit at the higher end.

Why do I still see ants after treatment?

With baiting this is expected and desirable — foragers need to survive long enough to carry the bait back to the colony. Activity usually rises briefly, then falls sharply over one to two weeks.

Are carpenter ants as damaging as termites?

They cause damage more slowly, because they excavate galleries for nesting rather than eating wood. But they target wood already softened by moisture, so their presence often indicates a second problem worth investigating.

Should I spray the ants I can see?

Generally no. Spraying visible workers kills foragers without touching the colony, and with some species it triggers budding — the colony splits into satellites and the infestation spreads.
