Our proven approach to black ant control
Black ants are one of the most persistent household pests. Getting rid of them properly requires experience, patience, and the right approach – not just more spray.
Why effective black ant control may require multiple treatments
In some homes, particularly where there is heavy black ant activity both inside and outside, a single treatment may not be enough.
Effective black ant control is about eliminating the colony, not just the ants you can see. While an initial treatment targets the primary nest around your home, other nearby colonies can naturally move into the area over time.
For this reason, follow-up treatments may be required to progressively reduce ant activity and establish a buffer zone around your home. This approach helps prevent re-infestation and delivers more reliable, long-term control.
Black ant treatment in South East Queensland
Black ants are a pervasive problem across South East Queensland, especially in warm, humid weather.
If you’re seeing ants repeatedly, there’s almost always an established nest nearby – and surface sprays won’t solve it.

Termidor spray – the best treatment for black ants
New non-repellent spray that has guaranteed results on black ants – inside and outside of your home
Termidor for ant control
As a homeowner, you know how frustrating trying to get rid of ants in your house (especially since trying to do it yourself can make things worse!). Fortunately, for practical, professional ant control, you can count on TERMIDOR®.
TERMIDOR has delivered unparalleled termite control since it was first introduced onto the Australian market in 2002. The key reasons for this success are that TERMIDOR is non-repellent plus it has the unique ‘Transfer Effect™’. These key attributes make TERMIDOR the ultimate social insect control agent. As ants are also very social insects, it makes perfect sense to bring the power of TERMIDOR to help in the battle against the hardest to control pests.
To control ants, it’s important to target them where they live. Chances are, ants, and some of the other pests in your home, actually live in nests outside. The key to controlling ants is to target them where they live—which is exactly what TERMIDOR does. By applying TERMIDOR to your house’s outside exterior foundation walls, your pest professional creates a treated area of protection.
How termidor controls ants
In the last decade, the professional pest control industry has been revolutionised by new control technologies, especially in the area of non-repellents or “undetectable” liquid treatments like TERMIDOR. Unlike older insecticides, TERMIDOR can’t be smelled, tasted, or even felt by pests. So they crawl through the treated area, unaware that ingesting treated materials or merely contacting the insecticide will cause them to die.
The unique transfer effect™
TERMIDOR is unique because it even controls ants that never make direct contact with its active ingredient. Ants are social insects that live together in large colonies and feed and groom each other. They need only make contact with other ants that have been exposed to TERMIDOR. The “Transfer Effect™” makes most of this. It’s a key reason why no other insecticide performs as well as TERMIDOR. This “Transfer Effect™” means you’ll see TERMIDOR affecting ants in one to three days and most species will be controlled within the first week following the treatment.
Using ants behaviour
Recent independent research that tested 8 Ant control insecticides, concluded that only TERMIDOR was horizontally transferred among nestmates to provide significant secondary kill in Argentine ant colonies. Interestingly one of the reasons for this excellent result lies in the behaviour of the ants themselves. Ants have developed a behavioural trait of removing dead individuals from the nest, referred to as ‘necrophoresis’. Necrophoresis is a crucial ‘Transfer Effect™’ pathway whereby healthy ants are contaminated upon removing TERMIDOR affected ants from the nest. A successful product needs to be relatively slow-acting, non-repellent and have the ability to transfer from one ant to another. Couldn’t get a better description of how TERMIDOR works.
1. Why do black ants keep coming back after I’ve sprayed them?
Most sprays only kill the ants you can see. Black ants live in large colonies, often with multiple nesting points, and the workers you see are just a small part of the problem. If the nest isn’t targeted, the colony simply replaces them and activity returns – sometimes worse than before.
Professional treatment focuses on eliminating the source of the infestation, not just surface activity, which is why it delivers longer-lasting results.
2. Is black ant treatment safe for my family and pets?
Yes, when applied correctly by a licensed professional. At Conquer, treatments are selected for effectiveness first and applied with precision, not blanket spraying. We use products and methods that are suitable for residential environments and take into account children, pets, and sensitive areas of the home.
Our technicians will also provide clear advice on access and re-entry, so you know exactly what to expect.
3. Will the treatment get rid of the nest, or just the ants I can see?
Effective black ant treatment is designed to deal with the nest. Ant control is about stopping the colony, not chasing individual ants around the house. Depending on the species and nesting location, treatments are chosen to spread through the colony and eliminate the source, which is what stops ongoing activity.
That’s the key difference between professional treatment and temporary solutions.
4. How long will the treatment last, and will the ants come back?
When the nest is properly targeted, most homes see a significant and lasting reduction in ant activity. While ants are common in South East Queensland and can forage from surrounding areas, effective treatment dramatically reduces re-infestation.
If conditions change or new activity appears, early intervention makes it much easier to control – which is why ongoing advice from an experienced technician matters.
