How to stop ants from coming into the house?

Ants are a persistent issue for Australian households, especially during the warmer months from September to February. From Argentine ants marching through your kitchen in Sydney to bull ants trudging in from rural backyards in Queensland, these pests can spoil food and become a real nuisance. Preventing ants from entering your home is essential for a comfortable living space. This guide shares 10 practical ways to stop ants from invading your Australian home, with insights from Rentokil pest control experts.

Top 10 ways to stop ants from coming inside

Sick of seeing ants marching through your kitchen? You're not alone. Here are the top 10 effective ways to stop ants from entering your house.

1. Seal up entry points

Ants can squeeze through the smallest cracks. Start by checking your home for gaps:

Look at walls, foundations, and around windows or doors.
Use caulk or silicone to fill cracks and seal openings.
Pay attention to pipes or wiring entering your home.

Sealing these spots can make a big difference in busy cities, where urban ant species thrive.

2. Maintain a clean kitchen

Food scraps draw ants inside faster than anything. Keep your kitchen tidy:

Wipe down benches and floors daily to remove crumbs.
Store pantry items like sugar or bread in sealed containers.
Use rubbish bins with tight lids and empty them often.

This habit is necessary in warm areas like Brisbane, where ants stay active all year.

3. Cut off water sources

Ants need water to survive, and damp spots can attract them. Take action:

Fix leaking taps or pipes as soon as you spot them.
Empty pet water bowls when not in use.
Keep bathrooms and laundries dry.

Coastal brown ants, common near Adelaide’s shores, often seek out moisture, so this step is vital in coastal regions.

4. Watch for ant types

Different ants need different approaches. Australia has a range of species:

Argentine ants love sweets and form large colonies in urban spots like Canberra.
Bull ants, with painful stings, roam rural areas and gardens.
Coastal brown ants pop up in damp, coastal homes.

Knowing what you’re dealing with helps you target the problem—Rentokil can identify and treat them effectively.

5. Tidy your outdoor areas

Ants often nest outside before moving in. Stop them early:

Trim trees and shrubs away from your house.
Clear away leaves, wood piles, or other debris.
Keep compost bins sealed and away from doors.

Spring and summer, when ants are busiest, are the perfect times to focus on this, especially in suburban Sydney or Perth.

6. Use baits wisely

Ant baits can hit the colony at its source. Here’s how:

Place baits near ant trails, like along walls or benches.
Let ants take the bait back to their nest undisturbed.
Be patient, it might take a few days to work.

Rentokil advanced baiting systems are built for Australian ants, offering a step up from shop-bought options. For safety and chemical use guidelines, check the Australian Pesticides and Veterinary Medicines Authority (APVMA) website.

7. Know when to call the experts

Some ant problems are too big for home fixes. Get help if you see:

Large groups of ants are in several rooms.
Signs of nests inside walls or floors.
Ants that keep coming back no matter what you try.

Rentokil offers customised treatments from Cairns to Hobart to tackle stubborn infestations.

8. Get ready for warm months

Ants love Australia’s hot seasons. Be proactive:

Check for entry points before spring starts.
Step up cleaning efforts in summer.
Plan with professional support if needed.

Early preparation helps manage ant activity in homes, particularly in areas like Queensland where warmer conditions increase ant presence.

9. Limit food access outdoors

Outdoor eating can invite ants closer. Manage it:

Clean up after barbecues or picnics right away.
Store pet food indoors or in sealed containers.
Avoid leaving sugary drinks outside.

This is especially useful in regional areas where bull ants might wander in from nearby bushland.

10. Understand why it matters

Ants aren’t just pesky—they can cause issues:

They spread germs by crawling over food.
Some, like bull ants, sting and cause pain.
Large numbers can disrupt daily life.

Staying on top of prevention is worth the effort in humid spots like Queensland or coastal NSW, where ants thrive.

Keeping ants out of your Australian home means staying vigilant—sealing gaps, cleaning up, and acting fast. While minor ant problems can sometimes be managed alone, bigger infestations need professional know-how. Rentokil brings specialised tools and local experience to solve ant issues for good.

Common ant myths

Misunderstandings about ant control can waste time and effort. Here are clear facts to set the record straight, tailored to Australian homes:

Myth: All ants are just a nuisance

Not true—some ants pose real risks. In rural Victoria, bull ants deliver painful stings that may need medical care, especially for those with allergies. Unlike smaller urban ants in Sydney, these aggressive species demand swift action. Rentokil technicians identify ant types and apply targeted treatments to keep your home safe.

Myth: DIY efforts are enough

While home attempts might reduce visible ants, they often miss the colony. Argentine ant nests can persist without professional help in Brisbane's humid suburbs. Rentokil uses advanced tools to locate nests and manage pest activity, supporting longer-term solutions for homes in Perth and Canberra.

Myth: Ants only seek food

Food isn’t their only target. Moisture draws ants, too, especially coastal brown ants in Darwin’s damp homes. Leaky pipes or wet laundries can become ant hotspots. Rentokil inspections pinpoint water sources and create plans to stop infestations.

Myth: Ants are only a summer problem

Ants stay active year-round in Australia’s varied climates. In cooler Tasmanian winters, they seek warmth inside walls or under floors. In warm Cairns, activity never stops. Rentokil's local expertise ensures tailored strategies for every season and region, from Adelaide to Hobart.

Clearing up these myths helps homeowners act smarter. Rentokil’s specialised services precisely tackle ant issues by identifying ant species and using local knowledge to address problems in urban Melbourne or rural Queensland. Contact us for an inspection to protect your home today.

Seasonal maintenance checklist for ant prevention

Australia’s varied climate influences ant activity, from Queensland’s humid summers to Tasmania’s cooler winters. A tailored seasonal plan helps homeowners prevent infestations year-round:

Spring (September–November): Before ant numbers surge, inspect and seal cracks around doors, windows, and foundations. In suburban Canberra, trim garden plants and clear debris to limit nesting spots for Argentine ants.

Summer (December–February): Step up cleaning routines and check outdoor areas, especially in coastal NSW, where humidity attracts coastal brown ants. Keep bins sealed and clear food scraps promptly.

Autumn and Winter (March–August): Look for signs of indoor nests in walls or under floors, as ants seek warmth in cooler areas like Hobart. Address damp spots to deter moisture-loving species.

This proactive strategy suits Australia’s distinct regions, from Perth’s dry summers to Melbourne’s mild winters. Rentokil offers specialised seasonal inspections, using advanced tools to identify and treat ant problems specific to your home.
