A LaSalle exterminator costs $399 for insects, $409 for mice and $429 for cockroaches. That is a unit up to a 4 ½, and it is a price rather than a range. You do not have to book a visit to find out: the full list is published below.
We are Local Extermination. 14 years around Montreal, 9,000 clients, 6 licensed technicians. Mice, rats and insects: that is all we do, and it is why we are quick at it.

In LaSalle We Treat a Building More Often Than a House
That is the difference between LaSalle and a suburb. The borough is duplexes, triplexes and three-storey walk-ups, and a good share of it rents. Shared walls, common plumbing chases, shared basements: one infested unit is almost never an isolated problem.
Two things follow. The treatment has to cover the units either side and the one below, or the problem comes back through the wall inside a month. And there is usually a landlord in the picture, so knowing who calls and who pays saves weeks.
The exceptions are the bungalows in the quieter sectors and the houses near the river, where it looks more like a suburb. Along boulevard Newman and around Angrignon it is the shops and restaurants that drive the work.
Cockroaches
An exterminator for cockroaches treats a building, not a door. This is the most common pest in LaSalle’s rental stock.
What you notice first: one in the kitchen at night when the light goes on. By the time you see one in daylight there are many more. Look for dark specks like ground pepper in drawer corners, behind the fridge and inside the stove housing.
Why LaSalle: roaches move through plumbing chases and shared walls, and a triplex gives them everything they need. They also arrive in cardboard: deliveries, second-hand furniture, boxes out of storage. The restaurants along boulevard Newman get the commercial version.
What makes treatment work: treating the units either side and the one below at the same time. Treating one unit while the neighbours do nothing moves the problem next door for a month. If you rent, that is a conversation with the landlord, not a solo project.
From $429 for a unit, $469 for a bungalow, $499 for a restaurant.
Bed Bugs
The hardest pest on this page, and the one where do-it-yourself does the most damage.
What you notice first: bites in a line or a small cluster on skin that was uncovered overnight, then small dark spots near the mattress seam. They hide in seams, headboard joints and baseboards.
Why LaSalle: turnover. In a walk-up they travel between apartments through baseboards and electrical outlets, and every 1 July moving day redistributes some of them. A piece of furniture picked up off the sidewalk in July is the most common way they get into a home here.
What makes treatment work: preparation and a second visit. They survive months without feeding, so one pass rarely finishes it. Store-bought sprays scatter them deeper into the walls.
From $429, rising to $549 for a 10 ½.
Mice
Mice are the pest we get called about most in autumn, and an exterminator for mice has one busy season here. One mouse in September is a family by January, and in a building it spreads fastest of all.
What you notice first: droppings along a baseboard, about the size of a grain of rice, then scratching inside a wall or above a ceiling, loudest around dusk.
Why LaSalle: a mouse fits through a gap the width of a pencil, and post-war construction offers plenty: the space around a pipe entering the foundation, the gap under a back door that has dropped on its hinges, the service entry. In a triplex one open gap feeds all three units.
What makes treatment work: finding the entry points, not just placing bait. Bait alone drops the population for a few weeks, then the next ones use the same hole. You get the list in writing.
From $409 for a unit, $429 for a house. Perimeter work on a house is $299.
Carpenter Ants
An exterminator for carpenter ants looks for water first. The ants do not eat wood, they hollow it out to nest in, and they want it damp.
What you notice first: large black ants indoors, fine sawdust under a windowsill or a balcony, and in May the swarm, winged ants at a window all at once. That means an established nest.
Why LaSalle: wooden balconies and the mature street trees. A back balcony whose wood stays wet, a window frame whose caulking has failed, a branch touching the roof: each one is a way in. The houses near the park and the river see more than the streets in the middle.
What makes treatment work: finding the moisture. Kill the nest and leave the water and a new colony finds the same soft wood next year.
Indoor treatment from $399. Outdoor from $129 for one visit or $327 for three.
Wasps, Rats and Spiders
Wasps peak in August. In LaSalle the classic nest is under a back balcony or at the top of an exterior staircase, where the overhang gives shelter and nobody looks until someone gets stung. One nest is $189, a full treatment is $259, and each extra nest is $39.
Spiders and silverfish follow humidity rather than food, so an exterminator for spiders is usually looking at a damp basement. Both start at $399 indoors.
Rats follow water and construction. The aqueduct canal, the riverbank near the rapids and the older industrial strips give them sheltered runs across the borough, and an excavation moves a colony into the surrounding buildings within days. They need a bigger opening than mice, so the entry points can be found and closed. From $409, perimeter control $299, and $230 for a single rat.

When LaSalle Pests Show Up, Month by Month
- March to May. Carpenter ants swarm as the wood thaws. Wasps start their first nests.
- June to August. Wasps peak in August, and the 1 July moving date redistributes bed bugs from one building to the next.
- September to November. The big one. The first cold nights push mice indoors.
- December to February. Quiet outside, busy inside: cockroaches and whatever came in during autumn breed in a heated wall.
The cheapest month to deal with mice is September. The most expensive is January.
Why Call Us Instead of Someone Else

Questions from LaSalle Residents
What Is the Average Cost of Pest Control in My Area?
The estimates floating around quote an inspection billed separately, then a treatment somewhere between a few hundred and over a thousand dollars. We do not work from an average. An indoor treatment is $399 for insects and $409 for mice in a 4 ½, the inspection is included, and the full list is on this page.
How Much Does Cockroach Extermination Cost?
$429 for a unit up to a 4 ½, $469 for a bungalow and $499 for a restaurant. The price follows the size of the home, not the severity of the infestation. In a triplex, budget for the building rather than one apartment, because treating a door at a time does not work.
Are Landlords Responsible for Pest Control in Quebec?
Yes, for an infestation the tenant did not cause. Quebec law requires the landlord to keep the dwelling fit to live in, and that covers cockroaches, mice and bed bugs arriving from elsewhere in the building. Tell them in writing and keep a copy. If you own a duplex or triplex, treating the building once is almost always cheaper than treating one unit three times.
What Is the Hardest Pest to Get Rid Of?
Bed bugs, easily. They hide where you cannot spray, survive months without feeding, and travel between units. That is why they are priced by the number of rooms rather than a flat fee, and why the follow-up visit is part of the job rather than an extra. Cockroaches come second, and for the same reason: in a building, neither of them stops at your door.
When Should I Call an Exterminator?
As soon as the signs repeat: noises several nights running, droppings you keep finding, a cockroach seen in daylight. Anything breeding indoors gets worse quickly. A mouse can breed at about six weeks old, so waiting a month does not cost you a month, it costs you a bigger job.
Do You Handle Raccoons, Skunks or Squirrels?
No. We do not do wildlife removal or relocation, so no raccoons, skunks, squirrels, groundhogs, birds or bats. We treat mice, rats and insects. If it is wildlife you need a licensed wildlife specialist, and we would rather tell you now than send a technician who cannot help.
The prices shown are estimates for the most common cases and can change without notice. We do our best to keep them current. Your final price depends on what the technician finds on site: how far the infestation has spread, how easy the affected areas are to reach, the condition of the property, and how many visits the job needs. You always get the exact price before any work starts.
