Where we work on pavement ants
The paver ant Tetramorium immigrans settles in paver joints and warm patios. In Longueuil and its neighbourhoods, our interventions mainly target the driveways and sidewalks of Old Longueuil and Saint-Hubert. In Brossard and the surrounding area, patios and paved driveways of single-family homes are the most affected areas. Our offer on the South Shore combines granular baits and PMRA residual insecticide. In Boucherville (Vieux-Boucherville), the paved entrances of recent residential areas concentrate active settlements. Further east, in Saint-Jean-sur-Richelieu, the sidewalks of Old Saint-Jean regularly see colonies in the joints. In Saint-Hyacinthe and the surrounding area, the stone landscaping of modern farmhouses and residences represents the majority of cases.
Did you know?
In some countries, where medicine is less developed, they can use armyworm ants to close their wounds. Indeed, this species of ant has a particularity, they find it very difficult to let go of a hold after a bite. They then put the ants on their wounds to make a kind of stitch.
Methods used for pavement ant extermination
When ants are seen inside your home or business, it is important to detect where the nest is located. To get rid of pavement ants in the long term, you need to eliminate the queen, which is the colony’s breeder. You can place many baits on the floors of the house that the ants will bring back to the other workers as well as to the queen. An insecticide can also be applied to at-risk surfaces.
Nova Extermination’s specialized technicians will solve your problem quickly and sustainably. We offer this affordable pavement ant extermination service in all cities on the South Shore of Montreal. We master the techniques to perform pavement ant extermination, and we use insecticides approved by the Ministry of the Environment to solve the problem.
TO PREVENT ANOTHER INFESTATION
Once our pavement ant extermination is done, we must then seal the entry points through which other ants could enter: holes and cracks around doors, windows and floors; foundation cracks; telephone cables, etc.). Nova extermination’s technicians can, if you wish, carry out this sealing for you.

Our company has a license in good standing from the Régie du Bâtiment du Québec (RBQ: 5734-75930-01) as well as from the Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST) to carry out the necessary patching work.

Frequently Asked Questions: Pavement Ants
What distinguishes pavement ants from other ants on the South Shore?
The paver ant is dark brown to black, about 3 mm long and can be recognized by the small mounds of sand or earth that it pushes between slabs, sidewalk cracks and driveways. In Montérégie, it is frequently found under paving stones, patios and along foundations. It enters homes mainly to look for sweet or fatty food.
Why do I see so many pavement ants in the spring and summer?
In the spring, the colonies become active again and the workers leave in search of food, hence their increased presence in the kitchens of Saint-Hubert and Chambly. In summer, during warm weather, swarms of winged individuals may appear when the colony is breeding. This seasonality explains why preventive outdoor treatments are often planned at the beginning of the summer.
Do pavement ants cause damage to my property?
They do not attack structural wood like carpenter ants, but their constant excavation of sand under slabs and pavers can, over time, cause surfaces to subside or shift. Indoors, they mainly contaminate food. The main issue remains the nuisance and persistence of colonies near the foundations.
How do you effectively treat pavement ants?
We combine perimeter treatment around the foundation with targeted baiting at entry points and along active runways. Since nests often hide under outdoor slabs and pavers, our technician inspects the landscaping to locate colonies. A coordinated external and internal approach yields the best long-term results.
What is the price of a treatment against pavement ants?
The price is determined on the basis of an evaluation, depending on the extent of the situation, the length of the area to be treated and the number of households identified. Nova being a paid service, no fixed amount can be announced without having seen the premises. The technician will present you with the cost before starting the intervention.
Can the pavement ant problem come back after treatment?
Because these ants nest outside and new colonies can be established from nearby land, we are talking about sustainable outcomes evaluated on a case-by-case basis rather than guaranteed permanent elimination. A well-executed treatment, sometimes accompanied by seasonal maintenance, greatly reduces their presence. Our technician will advise you on the preventive measures adapted to your land.
