Ant Extermination Services in Burlington, Oakville, Milton & Waterdown

Ontario’s warmer months encourage ants to forage, while food, moisture, and sheltered nesting spaces make residential properties attractive. A few ants along a baseboard or kitchen counter can be the first sign of a larger problem.

Halton Pest Control offers ant extermination in Burlington, Oakville, Milton and Waterdown to identify the species, assess activity, and apply targeted treatment inside and around your home. Prompt attention helps keep persistent trails from spreading, and carpenter ants deserve particular attention because they excavate wood to build their nests.

Our licensed technicians select professional-grade products and treatment methods suited to the ants present, whether that involves baiting or targeted applications. We also explain practical ways to reduce the conditions attracting them. With a treatment plan tailored to your property, Halton Pest Control can help bring the infestation under control and reduce recurring activity.

Signs of an Ant Infestation

• Ant trails along baseboards, counters, or window frames.
• Ants gathering around food, spills, or pet bowls.
• Winged ants emerging indoors or gathering near windows.
• Activity near sinks, plumbing, or damp wood.
• Small piles of soil near foundation cracks or walkways.
• Sawdust-like debris from carpenter ant nesting.

Common Ants in Halton Homes

Different ants need different treatment, so identifying the species comes first.

Carpenter Ants

• Large black (or black and red) ants; workers are roughly 6 mm long and queens up to about 13 mm.
• Nest in damp or softened wood, hollow trees, stumps and moisture-damaged parts of a home.
• Don’t eat wood, but excavate it to build galleries, leaving fine sawdust-like debris.
• Workers forage for sweets and protein, often at night.

Pharaoh Ants

• Tiny (about 2 mm) yellowish to light-brown workers.
• Prefer warm, humid indoor spaces and are common in heated buildings and multi-unit properties.
• Colonies have many queens and can split (“bud”) into new colonies when disturbed – which is why spraying them makes things worse.

Pavement Ants

• Small (about 3 mm) dark-brown to black ants.
• Nest under pavement, patio stones, slabs and along foundations, and forage indoors for food.
• Most visible in spring and summer, often trailing along floors and baseboards.

Some ants require different treatments: pharaoh ants need a bait-focused approach, while carpenter ant activity calls for attention to damp wood and potential nesting areas. We tailor our ant extermination service to what we find at your property, explain what to expect, and offer practical advice on moisture, food storage, and entry points to help reduce recurring problems.

Frequently Asked Questions

Do different ant species require different treatments?

Yes. A method that works for one species may be ineffective or make another infestation harder to control. Pharaoh ants typically require a bait-focused approach, while carpenter ant treatment involves assessing activity associated with wood and moisture. Product selection and placement should reflect the species and where the ants are active.

How can I tell if I have pharaoh ants?

Pharaoh ants are very small, typically about 1.5–2 mm long, with pale yellow to light brown bodies and a darker abdomen. You may notice persistent trails near kitchen cupboards, food, sinks, or warm areas around appliances and plumbing. Because other small ants can look similar, appearance alone may not confirm the species. Halton Pest Control can assess the activity and recommend appropriate treatment. Avoid spraying suspected pharaoh ants, as this can cause colonies to split and spread.

Why is spraying pharaoh ants a bad idea?

Spraying pharaoh ants, particularly with repellent insecticides, can cause colonies to split into smaller colonies through a process called budding. Queens and workers may move into other areas, spreading the infestation and making treatment more difficult. Sprays may kill visible ants without resolving the hidden colonies. Professional treatment generally uses carefully selected slow-acting baits that workers carry back to the colony. Avoid spraying suspected pharaoh ants and contact us for advice.

How can I tell if I have carpenter ants?

Carpenter ants are generally larger than many other household ants. Signs may include repeated sightings, winged ants indoors, or coarse sawdust-like material near wood. They excavate wood to create nesting galleries rather than eating it, often taking advantage of damp or damaged wood. Size alone is not enough for identification, so a technician should assess suspected activity.

Why am I still seeing ants after treatment?

Ants may remain visible while treatment takes effect. With baiting, ants may gather around the bait as they feed and carry it back to the colony. Continued sightings do not automatically mean treatment has failed. Contact us if activity does not decline within the timeframe your technician provides or begins spreading into new areas.

Should I spray ants after professional treatment?

Avoid adding sprays or other ant products unless your technician recommends them. Sprays can disrupt foraging trails, discourage ants from feeding on bait, or interfere with the treatment plan. Leave bait placements undisturbed and follow the instructions provided.

Can ants spread between apartments or condo units?

Yes, ants can travel through shared walls, plumbing routes, and other building spaces. Pharaoh ants are especially challenging in multi-unit properties because colonies may occupy several locations. Coordinated treatment involving property management and affected units may be needed to achieve control.

Is ant treatment suitable for homes with children and pets?

Our technicians apply products according to their label directions and explain any restrictions. Keep children and pets away from baits and treated areas, and follow the re-entry instructions specific to your treatment. Tell us about children and pets before service so we can plan appropriate placement and precautions.

Do I need to leave my home during ant treatment?

Interior spray treatments may require people and pets to leave for a specified period, while targeted baiting doesn’t require occupants to leave. Our technicians will explain any arrangements before your appointment and confirm when treated areas can be used again.

Do you offer a warranty for ant treatment?

Halton Pest Control offers a 6-month warranty for carpenter ant treatments and a 90-day warranty for pharaoh and pavement ant treatments. Exterior-only treatments do not include a warranty. Our technicians will explain the coverage for your service when booking. If ant activity continues or returns during the warranty period, contact our team to arrange a follow-up.
