Seeing a few ants in the kitchen can quickly turn into long trails appearing around benches, cupboards, windows and other parts of the home. Killing the ants you can see may provide temporary relief, but lasting control usually depends on understanding where they are coming from and addressing the colony behind the activity.
The best approach combines food and moisture management, identification of ant trails and entry points, appropriate treatment, and prevention. The ant species also matters because different species can respond differently to sprays, dusts and baits.
Quick Answer: How Do You Get Rid of Ants in Your Home?
Start by cleaning food residue, storing food securely and removing unnecessary moisture. Follow active ant trails to work out where ants are entering and, if possible, where the nest may be located.
For minor activity, these changes may significantly reduce the problem. Where ants keep returning, an appropriate ant bait or other registered treatment may be needed. Targeting the colony is generally more important than simply killing the worker ants you can see.
Why Do Ants Keep Coming Inside?
Worker ants leave their colony to search for food and water. When they find a useful food source, many species use chemical signals called pheromones to help other workers follow the same route.
This is why a few ants around the kitchen can turn into a noticeable trail.
Common things that can encourage ant activity include:
- crumbs and food residue
- sugary spills
- pet food
- open rubbish
- grease around cooking areas
- water around sinks
- leaking taps or pipes
- easy entry through cracks and gaps
Outdoor nests may also be located close to the building, allowing worker ants to repeatedly forage inside.
Step 1: Follow the Ant Trail
Before reaching for a spray, spend a little time watching where the ants are travelling.
Follow the trail in both directions. One end may lead towards food or water, while the other may show where ants are entering through a window frame, skirting board, wall opening or another small gap.
You may not always be able to find the nest. Ant colonies can be located outdoors, beneath paths, inside garden areas, around building foundations or within protected parts of a structure.
Even when the nest cannot be seen, knowing where ants are entering and feeding provides useful information for selecting the right control method.
Step 2: Remove Food That Is Attracting Ants
Good food hygiene is an important part of ant control.
Ants can survive on very small amounts of food, so pay attention to areas that are easily missed during everyday cleaning.
Useful steps include:
- wiping crumbs and spills from benches
- cleaning underneath small appliances
- keeping dry foods in sealed containers
- cleaning grease and food residue around cooking areas
- not leaving pet food out unnecessarily
- emptying rubbish regularly
- rinsing food residue from recycling
Cleaning alone may not eliminate an established colony, but it removes alternative food sources and can make other control methods more effective.
Step 3: Reduce Water and Moisture
Some ants are attracted to reliable moisture sources as well as food.
Check around:
- kitchen sinks
- bathrooms
- laundries
- dishwashers
- leaking plumbing
- pet water areas
- indoor pot plants
Fix dripping taps or leaking pipes where practical and avoid leaving unnecessary standing water.
Moisture management can be particularly useful when ant trails repeatedly appear around sinks, bathrooms or other damp areas.
Step 4: Identify Where Ants Are Entering
Ants can use extremely small openings around a building.
Common entry areas include:
- window frames
- door frames
- skirting boards
- cracks around walls
- gaps around pipes
- wall penetrations
- building foundations
Sealing practical gaps can help reduce future entry, but it is usually better to understand the source of the activity first.
If an active colony is nearby, ants may simply find another route when one opening is sealed.
Step 5: Decide Whether Ant Bait or Another Treatment Is Appropriate
There is no single treatment that is best for every ant infestation.
Victorian pest-control guidance recognises sprays, dusts and baits as different methods of controlling pest ants. The appropriate method depends on factors including the ant species and location of the nest.
How Does Ant Bait Work?
Ant bait is designed to be collected by worker ants while they are foraging.
The workers can then carry the bait back towards the colony and distribute it among other ants. This means bait can reach beyond the individual workers visible around your kitchen or bathroom.
Baiting can take time. Seeing ants feeding on bait does not mean you should expect the trail to disappear immediately.
The bait also needs to be attractive to the particular ants involved. Different ant species and colonies may prefer different food sources at different times.
What About Ant Spray?
Sprays can be useful in some ant-control situations, including treatment of particular nesting sites, travel areas or entry locations when the product is suitable for that use.
However, spraying every visible ant is not always the best strategy.
Some species require a different approach. Victorian Department of Health guidance specifically warns that spraying Pharaoh’s ants can fragment colonies and encourage groups to establish new nests.
This is one reason species identification can become important when an infestation persists despite repeated DIY treatment.
Why Killing the Ants You See May Not Solve the Problem
The ants walking across your bench are usually worker ants. They represent only part of the colony.
An ant colony can contain workers along with developing ants and one or more reproductive queens, depending on the species.
If treatment only kills exposed workers while the colony remains active, more ants can continue appearing.
This explains a common experience where someone sprays an ant trail, sees no ants for a short period, and then notices another trail a few days later.
Successful ant management should focus on the source of the infestation rather than repeatedly treating only the insects that happen to be visible.
What Types of Ants Are Found Around Melbourne Homes?
Australia has thousands of ant species, although only a relatively small number regularly become household pests.
Victorian homes can experience several pest ant species, including black house ants, white-footed house ants, Argentine ants and other species that nest in or around buildings.
Their behaviour can vary considerably.
Some primarily nest outdoors and send workers inside to forage. Others can establish nests in wall cavities, ceilings, behind cupboards or other protected parts of a building.
Food preferences can also differ. Some ants readily seek sweet foods, while others may favour proteins, fats or different food sources.
This variation is why identifying the ant and understanding its behaviour can improve treatment selection.
Do Natural Ant Remedies Work?
Many household substances are promoted online as natural ant repellents, including vinegar, citrus, peppermint oil and cinnamon.
Some strong-smelling substances may temporarily interfere with ant trails or discourage activity in a particular area. That does not necessarily mean the colony has been controlled.
Cleaning an ant trail can still be useful because it removes food residue and may disrupt some of the chemical trail used by foraging ants.
If ants repeatedly return to the same room, focus on why they are entering and where the colony is located rather than relying entirely on household repellents.
Should You Seal Ant Entry Points?
Sealing cracks and gaps can form part of long-term ant prevention.
Look around window frames, doors, plumbing penetrations and other places where trails are entering the building.
However, exclusion works best alongside control of the existing activity. If ants are nesting nearby or inside part of the structure, simply blocking one visible route may cause them to use another opening.
Once the infestation is under control, sealing suitable entry points can help reduce future foraging inside the home.
How Can You Stop Ants From Coming Back?
After ant activity has been controlled, make the property less attractive to future colonies.
- Keep kitchen benches and floors free from food residue.
- Store pantry foods in sealed containers.
- Clean pet feeding areas regularly.
- Repair persistent plumbing leaks.
- Keep rubbish containers closed.
- Seal practical cracks and gaps around the building.
- Trim vegetation where it creates direct access to the structure.
- Monitor areas where ant trails have previously appeared.
Outdoor conditions matter as well. Gardens, paving, retaining walls and other protected locations can provide nesting areas close to a house.
When Should You Call Pest Control for Ants?
Professional ant control becomes worth considering when ant trails repeatedly return, the nest cannot be located, activity is occurring in several parts of the property, or DIY treatments have provided only temporary results.
A pest-control technician can assess where the ants are feeding and travelling, identify the likely species where possible, and select a treatment suited to the infestation.
Depending on the situation, treatment may involve baiting, targeted liquid treatment, dusting or a combination of methods.

How Long Does It Take to Get Rid of Ants?
The timeframe depends on the species, colony size, nest location and treatment being used.
Direct treatment of an accessible nest may produce a different result from baiting a colony that cannot be reached directly.
Bait treatments can require patience because worker ants need time to collect and distribute the bait. Severe infestations may also require follow-up treatment.
Rather than judging treatment by whether every ant disappears immediately, monitor whether trails and overall activity are declining.
Frequently Asked Questions
What is the fastest way to get rid of ants in the house?
Start by removing accessible food and water, then follow the ant trail to identify where the ants are entering and feeding. If the colony or nest can be located, treatment can be targeted more effectively. Killing individual workers may give quick visible results without controlling the colony. Persistent infestations usually require a method suited to the particular ant species and nesting location.
Why do ants keep coming back after I clean?
Cleaning removes food sources but does not necessarily remove the colony. Worker ants may continue entering from a nest outdoors, inside a wall cavity or elsewhere around the property. They may also be searching for water. Follow returning trails to identify entry points and consider whether a colony-focused treatment is needed if ants continue appearing despite good sanitation.
Does ant bait kill the whole colony?
Ant bait is intended to be collected by workers and transferred back through the colony. When the correct bait is attractive to the species and used appropriately, it can provide colony-level control. Results are not instant, and effectiveness depends on factors such as species, competing food sources and bait placement. Always use household pest-control products according to their approved label directions.
Should I spray ants when I see them?
Spraying visible ants may kill exposed workers, but it may not reach the colony responsible for the infestation. Treatment choice also depends on the species. Some ants can respond poorly to inappropriate spraying. If trails repeatedly return after surface spraying, further spraying may not solve the underlying problem and identifying the species and colony location becomes more useful.
Why are ants suddenly appearing in my kitchen?
Ant workers may have located a new food or water source and established a trail between it and their nest. Crumbs, sugary residue, grease, pet food and moisture around sinks can all encourage foraging. Seasonal and weather conditions can also influence ant movement. Clean the food source and follow the trail to see where the ants are entering.
When should I get professional ant treatment?
Consider professional treatment when ants return repeatedly, appear throughout several areas, seem to be nesting inside the building, or DIY methods have not controlled them. Professional assessment is also useful when the species is unclear because ant behaviour can affect which treatment works best. In Victoria, pest-control operators applying pesticides commercially must hold the appropriate licence.
