How to Get Rid of Ants Permanently in Sydney

How we control ants 100% in Sydney

We eliminate the entire ant colony using non-repellent baiting systems and targeted residual treatments. Ants carry bait back to the nest, allowing the colony and queen to be destroyed at the source rather than only killing visible ants.

Most infestations are controlled within 1–3 weeks, depending on species and severity.

Targets queen and colony for permanent elimination, not surface-level ants

About This Service

Guarantee

If ants remain active after 6 weeks, we return and re-treat the affected areas at no additional cost (within warranty conditions). 

Hygiene conditions

Good hygiene plays a major role in long-term ant prevention. Food crumbs, spills, open bins, pet food, and moisture can attract ants back into treated areas.

Environmental reinfestation

Environmental reinfestation can also affect warranty coverage. Ants may return from nearby gardens, mulch, paving, trees, or untreated outdoor areas.

Structural entry points being addressed

Structural entry points are another key factor. Gaps, cracks, wall penetrations, window frames, door seals, plumbing access points, and other openings can allow ants to re-enter the property.

Safety Information

All products used are:

  • APVMA-approved
  • Low odour
  • Non-staining
  • Water-based or gel formulations

Once dry, treated areas are safe for:

  • Children
  • Dogs
  • Cats
  • Household pets

Technicians apply products in targeted areas such as cracks, skirting boards, and entry points to minimise exposure.

All ant treatments are carried out using Integrated Pest Management (IPM) principles, following Australian pest control regulations and APVMA-approved products.

Treatment strategies are based on:

  • Ant colony behaviour and pheromone trails
  • Species-specific baiting formulations
  • Non-repellent transfer technology
  • Structural entry-point mapping
  • Environmental nesting analysis

These methods align with professional pest control standards used across NSW residential, commercial, and strata properties.

Inside the Home

Outside the Home

Ants everywhere!

Why Ants Are Invading Your Home

Ants enter Sydney homes searching for:

  • Food crumbs
  • Sugary residues
  • Moisture sources
  • Pet food
  • Warm shelter

Common entry points include:

  • Window gaps
  • Door seals
  • Wall cracks
  • Plumbing penetrations
  • Paving joints

Once ants find a food source, they leave pheromone trails that attract thousands of others.

6

Month Warranty — Internal

All internal ant bait treatments carry a full 6-month warranty. If ants persist after 6 weeks, we return to your property at zero cost.

3

Month Warranty — External

External Termidor perimeter treatments are covered for 3 months. Ongoing ant activity within warranty is resolved with a free follow-up visit.

Our Process

Professional Ant Treatment Process

Internal Ant Treatment
Used for active infestations inside the home.

What we do:

• Apply low-toxicity gel bait along ant trails
• Treat kitchens, bathrooms, cupboards, and skirting boards
• Target entry points and nesting pathways

How it works:

Worker ants carry bait back to the nest and distribute it throughout the colony, eliminating the queen and reproductive cycle.

External Ant Treatment

Used for outdoor nesting and perimeter control.
Treatment areas:
• Garden beds
• Retaining walls
• Paving joints
• Pathways
• Perimeter walls
• External entry points

We use professional non-repellent residual products (including fipronil-based systems such as Termidor where appropriate).

Ants unknowingly carry the product back into the colony, eliminating nests hidden: • Under concrete • Beneath pavers • Inside wall voids • Under soil and landscaping

Our Process

Why Ants Keep Coming Back After Spraying

Most DIY ant sprays are repellent-based, meaning they:

  • Kill visible ants only
  • Cause colonies to relocate
  • Create multiple satellite nests

This leads to recurring infestations.
Professional treatments use non-repellent systems, which allow ants to:

  • Walk through treated areas
  • Carry bait back to the colony
  • Spread it to the queen and larvae

This is the only method that results in complete colony elimination.

I have been using Sydney's Best Pest Control for the last couple of years, and they have always been very professional and helpful, addressing any issues or concerns that I may have had and were kind enough to take the time to walk through the best options and had the best advice on how to proceed. I would happily recommend this service to anyone.

I have used many pest control companies and ALL of them had to return to correct their work as pests continued to return. Until I met Pest Control Sydney. Leanne is super magnificent, delivers what is promised and her pest control team are polite, confident and get their job done. I cannot recommend them enough. I have scheduled them in for every 6 months. Well done guys.

I've used this compahy in a few apartments I've lived in for various pests and the admin staff, Leanne and Saira are always really friendly. I've had the same guy come out and spray my apartment each time. He's always very friendly and efficient with the job. Surprisingly I've never got his name but he's always great. I'd happily recommend this company and have done to friends. It's well worth the investment. There's certain pests you just can't get rid of yourself so you need to get the experts in.
