What Are Pavement Ants?
Pavement ants are small, dark ants that get their name from nesting under sidewalks, driveways, patio stones, and concrete foundation slabs. They’re one of the most common ants in Ontario homes and often find their way inside through cracks in basement floors and foundations. Pavement ants will eat almost anything, from sweets and grease to crumbs and pet food, so kitchens and pantries are a frequent target. A colony can have thousands of workers and several queens, which is why pavement ants are one of the species our ant control services treat most often.
How to Identify Pavement Ant
| Colour | Size | Legs | Antennae | Shape | Region |
|---|---|---|---|---|---|
| Dark brown to black, lighter legs | About 1/8″ long | 6 | Yes, elbowed | Found throughout Canada |
Pavement ants are small and uniform in size, with lighter-coloured legs and antennae. Up close, you’ll see fine parallel grooves on the head and thorax, a pair of small spines on the back, and two distinct nodes between the thorax and abdomen. Winged pavement ants may appear indoors in late spring and summer when colonies send out new queens.
Signs You Have a Pavement Ant Problem
- Small piles of displaced soil or sand along driveway cracks, sidewalk edges, and patio stones
- Trails of small, dark ants along baseboards, countertops, and kitchen floors
- Ants coming up through cracks in basement floors or along the foundation
- Winged ants appearing indoors, especially in late spring and summer
- Large groups of ants fighting on sidewalks or driveways in spring, a common sign of neighbouring colonies
- Ants gathering around pet food bowls, crumbs, or sticky spills
- Ant activity indoors during winter, which often means the colony is nesting under a heated slab
Keeping Pavement Ants Out of Your Home
- Seal cracks in the foundation, basement floor, and around windows, doors, and utility entry points.
- Repair gaps and cracks in driveways, walkways, and patio slabs next to the home.
- Store food and pet food in airtight containers and wipe up crumbs and spills quickly.
- Clean pet bowls regularly and avoid leaving pet food out overnight.
- Keep kitchen counters, floors, and pantry shelves clean and free of food residue.
- Dispose of garbage regularly and keep outdoor bins sealed and away from entrances.
- Fix leaking pipes and reduce moisture in basements and crawl spaces.
- Keep mulch, stones, and landscaping debris pulled back from the foundation.
- Trim shrubs and plants so they don’t touch the siding.
- Inspect potted plants, firewood, and items stored outdoors before bringing them inside.
Health & Property Risks of Pavement Ants
-
Food Contamination
Pavement ants forage through garbage and outdoor debris before moving over counters and food, which can contaminate what they touch
-
Minor Stings and Bites
Pavement ants are not aggressive, but they can bite or sting when disturbed, causing mild irritation
-
Displaced Pavers and Soil
Nesting colonies push out sand and soil beneath patio stones and walkways, which can leave them uneven over time
-
Year-Round Indoor Activity
Colonies nesting under heated slabs can stay active through winter, bringing ants indoors outside the usual season
-
Large, Growing Colonies
With multiple queens and thousands of workers, a colony can keep sending ants indoors until the nest itself is treated
Our Pavement Ant Removal Process
Step 1. Consultation and Inspection
A licensed technician inspects your property inside and out to locate nests under slabs and pavement, ant trails, and the cracks they're using to get in.
Step 2. Full-Site Inspection Report
You'll get a clear summary of what we found: nest locations, entry points, food sources, and how widespread the activity appears to be.
Step 3. Custom Pest Control Action Plan
We build a targeted treatment plan around baiting, perimeter treatment, and exclusion, tailored to where the colony is nesting and how it's getting inside.
Step 4. Putting Your Plan Into Action
We treat colonies at the source and help seal the cracks and gaps they're using, so new ants can't follow the same trails indoors.
Step 5. Guidance on Staying Pest-Free
We confirm activity has stopped and provide you with a list of steps you can take to prevent re-infestation.

Frequently Asked Pavement Ant Control Questions
How do you permanently get rid of pavement ants?
To permanently get rid of pavement ants, you need to eliminate the colony at its source, not just the ants you see. That means treating nests under slabs and pavement, sealing the cracks ants use to get inside, and removing easy food sources. Because new colonies can move in from neighbouring yards, ongoing inspections through a program like our Home Protection Plan help keep them from returning. Every job is backed by the GreenLeaf 100% Satisfaction Guarantee.
How can I control pavement ants on my own?
You can reduce pavement ant activity by cutting off food and entry points. Store food and pet food in sealed containers, clean up crumbs and spills quickly, and seal cracks in the foundation, basement floor, and around doors and windows. Store-bought baits can help with small problems, but DIY methods rarely reach colonies nesting under concrete. If ants keep coming back after a few weeks, professional treatment is usually needed.
What time of year are pavement ants most active?
Pavement ants are most active from spring through early fall. They’re especially noticeable in spring, when colonies expand and large groups of ants battle over territory on sidewalks and driveways. Winged ants usually appear in early to mid-summer. Colonies nesting under heated slabs or basement floors can stay active indoors through the winter.
What is the best ant killer for pavement ants?
Slow-acting ant baits are generally the most effective option for pavement ants. Worker ants carry the bait back to the nest and share it with the colony, including the queens, which a contact spray can’t reach. Pavement ants shift between sugary and protein or greasy foods, so the bait needs to match what they’re feeding on. Avoid spraying near baits, as it can kill the workers before they carry the bait home.
What is an ant's worst enemy?
In nature, an ant’s worst enemy is often another ant colony. Pavement ants regularly fight neighbouring colonies over territory. They’re also preyed on by spiders, birds, beetles, and other insects. Around your home, though, the most effective defence is removing what they need to survive: easy food, moisture, and open cracks to get inside.
What gets rid of ants immediately?
A spray of soapy water or a vacuum will get rid of visible ants right away, and wiping the area with a vinegar-and-water solution removes the scent trail other ants follow. These methods only deal with the ants in front of you, though. The colony keeps sending new workers until the nest itself is treated, which is why a quick fix usually doesn’t last.
Are pavement ants harmful?
Pavement ants are mostly a nuisance, not a danger. They aren’t aggressive, but they can bite or sting when disturbed, causing mild irritation. They can contaminate food after foraging through garbage and outdoor debris, and nesting colonies can loosen sand and soil beneath patio stones and walkways over time. They don’t damage wood or a home’s structure.
How do I identify pavement ants?
Pavement ants are small, about 1/8″ long, and dark brown to black with lighter legs. Up close, they have fine grooves on the head and thorax, two small spines on the back, and two nodes on the waist. A strong clue is where you find them: small piles of soil along driveway cracks, patio stones, and sidewalk edges, or trails coming up through basement floor cracks.
What does professional pavement ant treatment involve?
Professional pavement ant treatment starts with a full inspection to find nests, entry points, and food sources. From there, a licensed technician applies targeted baits and perimeter treatments where the colony is nesting and travelling, rather than spraying living spaces, and helps seal the cracks ants use to get inside. We’ll follow up to confirm the activity has stopped and share steps to prevent re-infestation. Our licensed technicians serve homes and businesses across Toronto, the GTA, and Southern Ontario.
