Types of Ants We Remove in Toronto

Carpenter Ants
Camponotus pennsylvanicus
The largest ants in Ontario, black and up to 13 mm long. They hollow out damp wood to nest, leaving sawdust-like frass. A carpenter ant colony inside a wall can cause structural damage over time.

Pavement Ants
Tetramorium immigrans
Small dark-brown ants that nest under driveways, patios and foundation slabs. They push up little mounds of sand between pavers and march indoors along baseboards looking for food.

Pharaoh Ants
Monomorium pharaonis
Tiny yellow ants that nest inside heated buildings: apartments, condos, hospitals and restaurants. Spraying makes colonies split and spread, so they need a professional baiting program.

Field Ants
Formica species
Red-and-black or brown ants that build mounds in lawns and gardens. They forage into kitchens and sunrooms in spring and can bite when disturbed.
We also treat odorous house ants, acrobat ants and thief ants. Not sure which ant you have? Our technician identifies it during the free inspection.

Signs You Need Ant Control in Toronto
- Trails of ants along baseboards, counters or windows
- Ants in the kitchen, pantry or pet food bowls
- Small piles of sawdust or frass near wood trim
- Winged ants (swarmers) indoors in spring
- Sand mounds between patio stones and driveway cracks
- Rustling sounds inside walls or ceilings
- Ants returning after store-bought sprays
- Large black ants indoors in late winter, a sign of an indoor nest
The ants you see are a small fraction of the colony. Sprays kill the foragers and can make colonies split into several new ones, especially with pharaoh ants. Lasting ant control means finding the nest and using baits the workers carry back to the queen.
Ant Problems in Toronto Homes
Toronto's century homes in the Annex, Cabbagetown, Leslieville and Roncesvalles have aging wood porches, sill plates and window frames where carpenter ants nest once moisture gets in. The city's ravines, from the Don Valley to the Humber, bring huge carpenter ant populations right to backyard fences. Pavement ants nest under every laneway, patio and front walk, and pharaoh ants are a constant problem in the high-rises and older apartment buildings downtown.

Carpenter Ants Toronto: The Species That Causes Structural Damage
Carpenter ants are the most damaging ant species in Toronto. They are a structural threat, not a nuisance. Finding them is often a sign of a building problem beyond the infestation itself.
Camponotus pennsylvanicus is the largest ant in Toronto, reaching 12 to 25mm. It has two colony components: a primary outdoor colony and satellite colonies inside the home. Indoor carpenter ant Toronto swarmers in April confirm an established satellite colony is active.
Carpenter ants always follow moisture damage. They nest in wet wood near leaking pipes and drainage issues. Finding them indoors signals moisture in the structure. Treating ants without addressing the moisture source leads to recurrence.
Why Spraying Pharaoh Ants Spreads the Infestation
Pharaoh ants are the one Toronto ant species where spray is actively harmful. Using the wrong product on this species turns one infestation into a building-wide problem.
Monomorium pharaonis colonies have multiple queens. When disturbed by spray, queens move workers to new satellite sites throughout the building. This is called budding. One spray treatment can spread pharaoh ants to multiple floors and adjacent units within days.
Gel bait is the only solution. Workers carry it back to the queens. Colony collapse takes two to four weeks but is permanent. Correct species ID before any product is placed is the difference between fixing the infestation and spreading it.
Why Hardware-Store Ant Killers Do Not Solve the Problem
Most Toronto homeowners searching for ant pest control Toronto have already tried a spray. The ants disappeared briefly, then returned. Here is why.
Spray kills foraging workers on contact. It does not reach the colony. The pheromone trail between the nest and food source stays active. New workers follow it within 24 to 48 hours. Spraying pharaoh ants causes budding and multiplies the infestation. Short-residual products require repeated application, giving the colony time to recover between treatments.
Professional treatment reaches the colony directly. Gel bait is carried to the queens by foraging workers. Perimeter spray creates a lasting barrier. Insecticidal dust in wall voids eliminates carpenter ant galleries no surface spray can reach. Treating the source, not just the symptom, is the permanent solution.
Our Ant Control Process
- 1
Free ant inspection
We identify the species, follow the trails back to the nest and check for moisture-damaged wood that attracts carpenter ants.
- 2
Targeted colony baiting
We place professional gel and granular baits the workers carry to the queen, wiping out the colony at the source.
- 3
Nest and void treatment
For carpenter ants we treat the nest gallery directly through wall voids and damaged wood with non-repellent products.
- 4
Exterior perimeter barrier
We treat the foundation, entry points, mulch beds and patio cracks so new colonies cannot move in.
- 5
Follow-up and prevention
We check back to confirm the colony is gone and show you the moisture and food sources to fix.

Ant Control FAQ
Straight answers from our licensed technicians. Still have a question? Call (647) 471-1332, we are open 24 hours.
Are carpenter ants dangerous to my home?
Yes. Camponotus pennsylvanicus excavates wood to build galleries for nesting. The excavation weakens structural timber over time. Joists, sill plates, and framing near moisture damage are the most vulnerable. Carpenter ant swarmers indoors in spring confirm an interior satellite colony is already active. Early treatment prevents the repair cost that follows seasons of unchecked gallery excavation.
What are the flying ants I see every spring?
Flying ants are swarmers: the winged reproductive stage of an ant colony. Carpenter ant swarmers emerge April through May. Pavement ant swarmers appear slightly earlier. Indoor swarmers confirm the colony is established inside the building, not just foraging from outside. They are not a separate species. They signal an existing colony is large enough to reproduce.
Why do ants keep coming back after spraying?
Spray kills foraging workers but not the colony. The pheromone trail between the nest and food stays active, and new workers follow it within 48 hours. Spraying pharaoh ants causes budding and spreads the infestation. Professional gel bait is carried back to the queens, eliminating the colony at the source. Pest Control Pro applies species-confirmed treatment that reaches the nest directly.
How can I tell whether I have a pharaoh ant problem?
Pharaoh ants are tiny (1.5 to 2mm), yellowish-brown, and form long irregular trails through wall voids rather than along baseboards. Common in condos, hospitals, and older apartments. Tiny yellow-brown ants appearing far from visible food or entry points often indicate pharaoh ants moving through internal voids. Do not spray. A Pest Control Pro inspection confirms the species and applies gel bait-only treatment.
How long does ant extermination take in Toronto?
Pavement ant and carpenter ant treatments show clear results within seven to ten days. Pharaoh ant gel bait treatment takes two to four weeks for full colony collapse. A follow-up inspection confirms no active foraging trails remain before the job is closed.
How much does ant control cost in Toronto?
Ant control cost in Toronto depends on species, infestation severity, property size, and treatment scope. Pest Control Pro provides a transparent written quote after the on-site inspection. No hidden fees and no obligation to proceed after the visit.
Are your ant treatments safe for children and pets?
Yes. All products are Health Canada approved and PMRA-registered. Gel bait is placed inside enclosed harborage sites. Exterior spray is applied at foundation level and allowed to dry before re-entry. Re-entry timing is confirmed on every job.
How quickly can an ant exterminator near me respond?
Pest Control Pro dispatches same-day, 24 hours a day, seven days a week across Toronto and the GTA. Call before noon for same-day ant removal in most GTA locations. For ant exterminator near me or ant control near me response, Pest Control Pro is available evenings, weekends, and holidays.
Why do I have big black ants in my Toronto home?
Large black ants indoors are usually carpenter ants. Seeing them in late winter or early spring often means the colony is nesting inside a wall, deck or window frame, not outside. Book an inspection before they damage the wood.
How long does it take to get rid of ants?
Most colonies collapse within 3 to 10 days after baiting, as workers share the bait with the queen. You may see more ants for a day or two while they feed. That is normal and means the bait is working.
Should I spray the ants I see before you arrive?
Please do not. Sprays kill the foragers that would carry bait to the queen and can make some species split into new colonies. Just wipe the trail with soapy water and call us.
Are your ant treatments safe for kids and pets?
Yes. We use enclosed bait stations and Health Canada registered products placed in cracks, voids and outdoors, away from kids and pets. We explain exactly what was applied and where.
Do carpenter ants damage houses?
Yes. Carpenter ants do not eat wood but they excavate it to nest, weakening window frames, sill plates, decks and roof edges over time. Early treatment is much cheaper than repairing the wood.
Will the ants come back next year?
Ant pressure returns every spring. Our treatment eliminates the current colony and leaves a perimeter barrier. A seasonal plan keeps new colonies from moving in each year.

I had an amazing experience with Pest Control Pro when I needed help with a bed bug problem in my home in Toronto. Their team was incredibly responsive—they provided a free inspection the next day and clearly explained the treatment options. I ended up getting the Aprehend treatment, and within two weeks, there were no more signs of bed bugs! A few months later, I noticed a cockroach issue starting in the kitchen, and again, Pest Control Pro came through with a quick and effective cockroach treatment. Their professional pest control service is honestly one of the best I’ve used: fast, thorough, respectful of my space, and very affordable compared to other companies. Highly recommend Pest Control Pro if you’re looking for efficient pest control done right. Definitely my go-to for any pest issues from now on!Posted on Google![]()
