Common Ant Species We Treat in South Africa
Pretoria and Centurion are home to several ant species, correct ant identification is critical, as different species require different treatment methods. Treating the wrong ant with the wrong product can make the problem worse.
Our technicians identify the ant species before treatment to ensure the correct method is used.
Ant Species Commonly Found in South African Homes
Where they’re found:
Common in and around homes, kitchens, gardens, and along walls or paving.
Why they’re a problem:
Form large colonies and persistent trails, making infestations difficult to control.
Why DIY often fails:
Surface sprays rarely reach the colony, allowing the infestation to return quickly.
Where they’re found:
Common in gardens, lawns, paving, and around outdoor structures.
Why they’re a problem:
Attracted to food and moisture and can invade homes in large numbers.
Why DIY often fails:
Incorrect treatment can spread the colony and increase ant activity.
Where they’re found:
Common in lawns, gardens, and outdoor areas.
Why they’re a problem:
Aggressive ants that bite or sting and can pose a risk to children and pets.
Why DIY often fails:
Incorrect treatment can disturb the colony and increase activity instead of eliminating it.
Where they’re found:
Common in gardens, lawns, soil, and outdoor areas near buildings.
Why they’re a problem:
Create nests in soil and can enter homes in search of food.
Why DIY often fails:
Treating visible ants does not eliminate the nest beneath the ground.
Where they’re found:
Common under paving stones, driveways, walkways, and building foundations.
Why they’re a problem:
Nest under hard surfaces and can enter homes through cracks and gaps.
Why DIY often fails:
Surface treatments do not reach nests hidden beneath paving.
Where they’re found:
Common indoors, especially in kitchens, bathrooms, and warm indoor spaces.
Why they’re a problem:
Form multiple nests and spread rapidly when disturbed.
Why DIY often fails:
Incorrect treatment can cause colonies to split and worsen the infestation.
Where they’re found:
Common indoors, particularly in kitchens, pantries, and food storage areas.
Why they’re a problem:
Attracted to sugary foods and form visible trails inside homes.
Why DIY often fails:
Using the wrong products can repel ants without eliminating the colony.
Why DIY Ant Control Fails
Many homeowners try to solve ant problems using shop-bought sprays, powders, or home remedies.
While these products may reduce visible ant activity temporarily, they rarely eliminate the infestation completely.
Here’s why DIY ant control usually doesn’t work:
❌ Sprays Only Kill the Ants You See
- Most DIY products kill worker ants on contact, but they do not reach the nest or queen, which is often hidden underground, inside walls, paving, or foundations.
- As long as the queen survives, the colony will continue producing new ants.
❌ Ant Colonies Are Hidden and Complex
- Ants live in highly organised colonies that can stretch across multiple nesting points. Some species, such as Argentine ants, form multiple interconnected colonies, making surface treatments ineffective.
- Without professional inspection, nests are missed entirely.
❌ Wrong Products Can Make the Problem Worse
Using the incorrect chemical or method can:
- Increase ant activity instead of reducing it.
- Delay proper control, allowing infestations to grow.
- Cause colonies to split and spread.are missed entirely.
This is a common reason ants “come back stronger” after DIY treatment.
❌ No Residual or Long-Term Protection
- DIY sprays provide short-term knockdown only.
- They do not create a residual barrier or eliminate the colony at its source, which means reinfestation is likely within days or weeks.
✅ Why Professional Ant Control Works
Professional ant control focuses on:
- Correct species identification
- Targeted baiting systems carried back to the nest
- Colony-level elimination, including the queen
- Residual protection to prevent reinfestation
This approach delivers long-lasting results, not temporary relief.
📌 Expert Advice You Can Trust
At Greenline Pest Control, we believe in honest assessments and effective solutions.
If DIY methods haven’t worked, it doesn’t mean the problem is severe — it means the right treatment hasn’t been applied yet.
Our Professional Ant Control Process
Effective ant control is not about spraying surfaces — it’s about eliminating the colony at its source. At Greenline Pest Control, we follow a structured, professional process designed to deliver long-lasting results, not temporary relief.
Step 1: Inspection & Ant Species Identification
Every ant infestation is different.
Our technician will:
- Inspect indoor and outdoor areas .
- Identify the ant species involved .
- Locate nesting points, trails, and entry areas .
Correct identification is critical, as different ant species require different treatment methods.
Step 2: Targeted Treatment Strategy
Once the species and activity areas are identified, we apply a species-specific treatment plan, which may include:
- Professional ant baiting systems .
- Non-repellent treatments that ants carry back to the nest. .
- Targeted crack, crevice, and perimeter applications.
This approach allows ants to transfer the active ingredient throughout the colony, including the queen.
Step 3: Indoor & Outdoor Control
Effective ant control requires treating both inside and outside the property.
We focus on:
- Indoor activity areas (kitchens, cupboards, skirtings, plug points).
- Outdoor nesting zones (lawns, paving, walls, foundations).
- Creating a protective barrier to prevent reinfestation.
Step 4: Colony Elimination & Monitoring
After treatment:
- Ant activity may increase briefly as baiting takes effect.
- Colonies are gradually eliminated from within.
- Visible ant activity typically reduces significantly within 7–14 days.
This is a normal and expected part of professional ant control.
Step 5: Follow-Up & Prevention Advice
If required, we:
- Conduct follow-up treatments.
- Adjust baiting strategies..
- Provide practical prevention advice to reduce future infestations.
Our goal is not only to eliminate ants — but to keep them from coming back.
✅ Safe, Responsible & Compliant
All treatments are:
- Act 36 of 1947 compliant
- Applied by trained professionals
- Safe for families and pets when used as directed
- Environmentally responsible where possible
📌 Why This Process Works
- Targets the entire colony, not just visible ants
- Prevents recurring infestations
- Uses the right method for the right species
- Delivers long-term control, not quick fixes
Treatments We Use
Safe, Effective & Compliant Ant Control Solutions
At Greenline Pest Control, we use professional-grade ant control treatments that are targeted, effective, and legally compliant.
Every treatment is selected based on the ant species, infestation level, and environment — never a one-size-fits-all approach.
Professional Ant Baiting Systems
Ant baiting is one of the most effective methods for long-term ant control.
We use:
- Non-repellent ant baits.
- Designed to be carried back to the nest.
- Allows the active ingredient to spread through the entire colony, including the queen.
This method eliminates ants from the inside out, rather than just killing visible workers.
Residual Surface & Perimeter Treatments
Where required, we apply residual insecticide treatments to:
- Skirtings, cracks, and crevices.
- Entry points and ant trails.
- External foundations and perimeter areas.
These treatments provide ongoing protection and help prevent reinfestation after the colony has been eliminated.
Indoor & Outdoor Targeted Applications
Effective ant control requires treating both inside and outside the property.
Our treatments may include:
- Indoor treatment of kitchens, cupboards, bathrooms, and plug points.
- Outdoor treatment of paving, walls, lawns, garden beds, and foundations.
- Targeted nest treatment where colonies are located.
Environmentally Responsible Options
Where possible, we:
- Use low-toxicity, targeted products.
- Minimise chemical use through precision application.
- Avoid unnecessary spraying.
This approach protects:
- Families and pets
- Beneficial insects
- The surrounding environment
✅ Safe, Responsible & Legally Compliant
All products and methods used by Greenline Pest Control are:
- Registered and compliant with Act 36 of 1947
- Applied by trained, experienced technicians

- In line with SAPCA-recommended best practices
How Long Does Ant Control Last?
One of the most common questions we are asked is:
“How long will ant control last?”
The answer depends on ant species, infestation size, and environmental conditions, but professional ant control follows a predictable and effective timeline.
What to Expect After Treatment
First 24–72 Hours
- You may notice increased ant activity.
- This is normal, especially with baiting systems.
- Ants are actively carrying treatment back to the nest.
Within 7–14 Days
- Ant activity typically reduces significantly
- Colonies are gradually eliminated from within
- Visible trails disappear
Long-Term Results
- Once the colony (including the queen) is eliminated, ant activity stops.
- Residual treatments help prevent reinfestation.
- Most infestations are controlled with one professional treatment.
- Severe or multi-colony infestations may require follow-up visits.
Factors That Affect How Long Ant Control Lasts
- Type of ant species (some are more invasive)
- Size and number of colonies
- Rainfall and seasonal weather conditions
- Surrounding environment (gardens, paving, nearby structures)
Will Ants Come Back?
Ants may return if:
- New colonies migrate from neighbouring areas.
- Food sources are easily accessible.
- Structural entry points remain untreated.
This is why Greenline Pest Control focuses on colony elimination and prevention, not just short-term knockdown.

Frequently Asked Questions about Ant Pest Control
Answers to common questions about our pest control services in Pretoria & Centurion.
The cost of ant control depends on the ant species involved, the severity of the infestation, and the treatment method required. A professional inspection ensures the correct solution is applied, avoiding unnecessary repeat treatments.
Some treatments show results within a few days, while others may take several weeks to fully eliminate the colony. This depends on the ant species and whether baiting or residual treatments are used.
Yes. Treatments are selected and applied according to safety guidelines and are designed to minimise risk when used by trained professionals. Our technicians also provide clear after-treatment advice for your peace of mind.
Correct identification and professional treatment significantly reduce the risk of ants returning. Follow-up treatments and prevention advice help ensure long-term control rather than short-term relief.
Most DIY products only kill visible ants and do not eliminate the colony. In some cases, incorrect treatment can make the problem worse by causing the colony to spread or become more active.
Follow-up treatments may be recommended depending on the ant species and infestation severity. Our approach focuses on long-term control rather than temporary results.
