Ant Control Experts – Geelong, Surf Coast and surrounding areas
Professional ant control treatments are really the only way to control ants and reduce the risk of them coming back.
The main objective of pest control for ants is to keep ants out of the building, and supermarket products just aren’t up to the job. Our technicians combine interior treatments, exterior ant control around the perimeter and professional baits to deal with the nest itself, not just the ants you can see. At Geelong Pest Control we use a combination of specialist ant products and our knowledge of the various ant species to control the ant problem and exclude ants from re-entering for many months.
For a lasting solution to your ant problem call the ant experts at Geelong Pest Control.
Our professional ant treatments
The majority of our calls on ants are to get control of ants from inside the house (or business).
Our treatments follow a 4-step process:
Identify the species of ant and then try and locate the nest.
Treat areas of activity (ant trails and nest, if located)
Carry out a perimeter treatment around the building and ant entry points.
Destroy ant nests inside the house by using ant bait.
Our Professional Ant Spray
At Geelong Pest Control we can access professional, specialist ant products, that aren’t available in supermarkets or hardware stores. These sprays are non-repellent – the ants walk across the treated surface, pick up the insecticide and die. However, the ants don’t die immediately… and this is important. It means that ants coated in insecticide pass on some of the insecticide to other ants when they come into contact, magnifying its effect. In some circumstances this transfer effect can destroy the nest.
How do ant baits work?
Ant baits are a great product for eliminating ant nests, especially when the nest cannot be located. This is often the case when the ant nest maybe inside wall voids or roof cavities. Ant baits tap into the ant’s natural behaviours, leading to their own demise.
Ant baits are made up of an attractive food material and a slow-acting insecticide. Foraging ants find the bait and take it back to the nest, where it is fed to their nest mates, including the larvae and queen, destroying the nest. By killing the queen, no more eggs are produced, and the nest dies. Ant baits need to be slow acting so they can be taken back to the nest and spread around the colony before the ants realise something is wrong. This is often the case when the ant nest may be inside wall voids or roof cavities. Although ant baits have an impact within 24 hours, it can often take up to a week to completely kill the nest.
Exterior ant control: stopping ants before they get inside
Exterior ant control is the foundation of a lasting result. Our technicians apply a non-repellent treatment around the full perimeter of the building, covering the slab edge, weep holes, paths, paving, fence lines and the entry points ants use around doors, windows and utility pipes. Because the product is non-repellent, ants keep walking through the treated zone, pick up the insecticide and carry it back to the colony. We also target visible trails and nests in lawns, garden beds and between pavers. For Geelong properties dealing with invasive species like Argentine ants and coastal brown ants, this exterior barrier is what keeps ants out of the house for many months after the visit.
Types of ants in Victoria
The two main pest ants in Victoria are the Argentine ant and the coastal brown ant (also known as the big-headed ant). Argentine ants will often make their nests close to the surface in garden beds and coastal brown ants will make their nests underground in lawns and pavers, digging up dirt. Both are invasive ants (they aren’t native) and have similar characteristics that make them very annoying pests.
They create “super colonies” made up of numerous nests and multiple queens. As a result, they can take over whole neighbourhoods, and it is virtually impossible to remove every nest. Black house ants and white-footed house ants are also common invaders of Geelong homes, often trailing into kitchens or nesting in roof voids. To work out which species you’re dealing with, see our guide to Australian ant species and how to identify them.
The best way to deal with these ants is through “ant management” – use specialist ant sprays to reduce the ant numbers and keep the ants out of the house. Often this means regular ant treatments are required (generally once a year).


What to expect from our ant treatments?
Our ant treatments will have a big impact on ant numbers within 24 hours. But it can take a bit longer for the treatment to completely get on top of the problem, especially if we need to use ant baits to destroy the ant nest causing the problem.
All our ant treatments come with a 6-month warranty.
If you are in an area with major invasive ant problems, it is likely regular ant treatments will be required, as even if ant numbers are reduced after a treatment, they will eventually re-invade from surrounding areas.
What our customers say

How to prevent an ant problem
Ants most often come inside looking for food or moisture, so removing both makes your home far less attractive to them. Clean up food spills and dirty dishes promptly, and don’t leave uneaten pet food out overnight. Fill any cracks around windows, doors and utility pipes to stop ants entering the building.

Argentine ants, which are a major problem in Victoria like nesting in garden beds under mulch. As such, it’s best to avoid having dense garden beds against the house. With mulch and watering, it is an ideal environment for Argentine ants. Garden beds using pebbles as mulch, plants in pots and no watering system, are a far better option.
Frequently asked questions about ant control
The only lasting way to fix an ant problem is to deal with the nest, not just the visible trails. Professional non-repellent sprays and baits reach the queen and colony, while supermarket sprays only kill the workers you can see.
The cost depends on the ant species, the size of the infestation and your property, so we provide pricing by quote. Call us on 1300 135 519 and our team will give you a price tailored to your home or business.
Supermarket sprays are repellent, so ants simply avoid the treated area while the nest keeps growing. Invasive species like Argentine ants also have multiple queens across connected nests, so professional baits and non-repellent treatments are needed to knock out the colony.
Our ant treatments have a big impact on numbers within 24 hours. Where baits are needed to destroy a hidden nest, it can take up to a week for the colony to collapse completely, as the bait spreads through the nest.
Exterior ant control is a treatment applied around the outside perimeter of your home, covering entry points, paths, paving and garden edges. It intercepts ants before they get inside and carries the insecticide back to the nest.
Yes, safety is our number-one priority. We use registered professional products applied to label directions, targeting the areas where ants travel and nest. Just keep children and pets away from treated surfaces until they have dried.
