Professional insecticide gel is one of the most effective methods against pharaoh and pavement ants. Thanks to its retardant effect, the ants carry the product to the nest, contaminating the colony and reaching the queen.
Our technicians inspect cracks, entry points, wet areas and nesting sites. Where possible, we recommend sealing access points to greatly reduce the risk of reinfestation.
We apply professional products approved by Health Canada to strategic areas such as baseboards, cracks, garages, foundations, windowsills and other points of activity. Treatment is targeted to maximize effectiveness while limiting unnecessary exposure.
Professional baits are used for many types of ant infestations in homes, businesses and buildings. They provide long-lasting control by targeting ants' feeding behavior and their movement towards the colony.

An ant infestation may seem minor at first, but it often hides a well-established colony in walls, wood, foundations or damp areas. The mere presence of a few ants on a counter or near a window doesn't always indicate the true extent of the problem.
Our ant extermination method is based on four essential steps: inspection, identification, targeted treatment and lasting prevention.
Carpenter ants are among the most problematic, burrowing into damp wood to build their galleries. They can be found in walls, ceilings, frames, joists and other parts of the structure. The presence of large black ants, fine sawdust or repeated activity near wood may indicate a carpenter ant infestation.
An ant infestation is more than just a few visible insects. In many cases, the colony is already well established when the first signs appear in the home.
Here are the most common signs:
- Regular presence of ants in the kitchen, bathroom or near windows; ;
- ant trails on counters, walls or baseboards; ;
- fine sawdust or debris near the wood in the case of carpenter ants ;
- greater activity in the evening or early morning; ;
- repeated presence of ants near foundations, garages or wetlands.
If you observe these signs, a professional inspection can determine whether the infestation is active and identify the right treatment.
Over-the-counter products often eliminate only visible ants. The real problem is that the queen, main nest and satellite nests remain active. As a result, the infestation seems to subside for a few days, then returns.
An ant exterminator in Montreal uses methods adapted to actual ant behavior. This makes it possible to reach the colony, treat areas of activity and reduce the risk of reinfestation.
Each intervention generally includes :
- species identification ;
- infestation assessment ;
- an adapted treatment plan; ;
- prevention recommendations; ;
- follow-up depending on the type of intervention.
The aim is not to conceal the problem, but to resolve it in the long term.
At Extermi Pro, our priority is to solve your ant problem seriously, safely and sustainably. Depending on the type of infestation and the treatment carried out, our interventions may include a written guarantee of up to 1 year.
Our certified technicians ensure a rigorous approach that includes :
- a complete inspection of the affected areas; ;
- application of products approved by Health Canada; ;
- personalized recommendations to avoid reinfestation; ;
- follow-up when necessary.
Our approach is transparent, professional and adapted to the reality of your building.

The price of an ant exterminator in Montreal depends on several factors: the species of ant, the size of the infestation, the number of areas affected and the type of building. A carpenter ant infestation in a house does not require the same intervention as a Pharaoh ant infestation in an apartment building.
At Extermi Pro Inc. each situation is evaluated to recommend the most effective ant treatment. An inspection identifies the source of the problem and enables us to propose a quote adapted to the building's reality.

The pharaoh ants are small yellow ants that invade kitchens.
