Our ant control services in Trois-Rivières
Our certified exterminators work throughout the Trois-Rivières area on the two species behind most ant calls: the carpenter ant and the pavement ant. Every job starts with an on-site inspection and with identifying the species, because the bait and the dosage change from one to the other.
Carpenter ants in Trois-Rivières homes
Carpenter ants excavate wood softened by moisture to dig their galleries. They are the only species that reaches the structural wood of your house. Our technicians locate the main nest, almost always outdoors, then the satellite nests set up in the walls, the joists and the window frames. The species is described in detail on our carpenter ant extermination page.
Pavement ants along the foundation
Pavement ants nest under slabs, garage entrances and concrete steps, then move up toward the kitchen and the pantry through a crack in the foundation wall. We treat the outdoor nest and install a perimeter barrier along the foundation, with no damage to the structure. This treatment is part of our residential pest control , for single-family homeowners and for apartment buildings alike.
Ants in Trois-Rivières businesses
Restaurants, cafés, daycares and offices: our technicians drive unmarked vehicles and work outside business hours when discretion calls for it. Establishments under MAPAQ rules receive verifiable intervention records, covered by our commercial pest control and by the preventive integrated pest management program.
Our four-step ant extermination method
Four steps applied to every job in Trois-Rivières, from the first call to the follow-up visit.
Carpenter ants in your walls?
A certified exterminator inspects, identifies the species and gives you a fixed price before any work begins.
01/ On-site inspection.
Tracking the worker trails, the wood dust under the baseboards, the entry points and the main nest outside the building.
02/ Species identification.
Carpenter ant or pavement ant: the protocol, the bait and the dosage differ; a spring swarm of winged ants points the diagnosis.
03/ Targeted treatment.
Non-repellent baits approved by Health Canada, carried back to the queen by the workers, perimeter treatment of the foundation and caulking of the access points.
04/ Follow-up and guarantee.
A control visit confirms the colony is gone. Written guarantee handed over before the work, with a free return visit if the ants come back.
Downtown Trois-Rivières has houses whose basements sit on stone foundations and whose original joists have taken on water at least once. Our technicians probe the softened wood behind the basement finishes, around the ground-level windows and under the door thresholds, where a carpenter ant finds wood already soft enough to excavate. An old water infiltration, even one repaired long ago, leaves that wood vulnerable for years.
Between the St. Lawrence River and the Saint-Maurice River, basement humidity keeps that soft wood going from one season to the next. It also explains a colony that reappears after a surface treatment: the main nest stays outside, in a stump or a woodpile, and from there it feeds satellite nests lodged inside the walls. Our blog explains why ant colonies keep coming back and covers this back and forth between the outdoor nest and the building.

FAQ: ant extermination in Trois-Rivières
How much does ant extermination cost in Trois-Rivières?
A carpenter ant treatment generally runs between $300 and $800. The size of the building, the number of satellite nests and how hard the main nest is to reach all move the figure. Sealing the entry points, if it is required, adds $100 to $300. You get a free fixed-price quote before the work, with no supplement afterward.
Does my stone basement attract carpenter ants?
Often, yes. A stone foundation lets moisture through to the joists and the bottom of the walls. That softened wood is what the carpenter ant excavates to dig its galleries, without ever eating it. Our technicians probe the wood behind the basement finishes and under the door thresholds, then work back to the main nest, almost always outside the building.
Do you serve Cap-de-la-Madeleine and Pointe-du-Lac?
Yes. Our Trois-Rivières and Mauricie division covers the Vieux-Trois-Rivières, Cap-de-la-Madeleine, Trois-Rivières-Ouest, Sainte-Marthe-du-Cap, Saint-Louis-de-France and Pointe-du-Lac sectors, as well as Shawinigan, Louiseville and the MRC des Chenaux. One number for the whole region, (819) 991-4447, with certified technicians who come on site for the inspection.
What is the difference between carpenter and pavement ants?
The carpenter ant is large and black, it digs galleries in damp wood and leaves a fine sawdust under the baseboards. The pavement ant is smaller, it nests under slabs and concrete steps, then comes looking for sugar in the kitchen without touching the structure. Identifying the species decides the treatment.
Are the baits safe for children and pets?
Yes. Our technicians apply only products approved by Health Canada, at the dosages set by their Ministère de l’Environnement certification. The baits are placed out of reach, in the cracks, behind the baseboards and along the outside foundation. Precise instructions are given to you at the end of the job, based on the products used in your home.
When in the year should carpenter ants be treated?
Spring and early summer concentrate the calls, because the colony becomes active again and winged ants swarm indoors. Treatment stays possible all through the warm season, as long as the workers are moving and carrying the bait back to the queen. A fall inspection mainly serves to spot the damp wood before winter.
