What a Saint-Lambert Exterminator Costs
Most companies make you book a visit before they give you a number. We publish ours. A full indoor treatment in a 4 ½:
| Service | Price per visit |
|---|---|
| Mice Indoor | $409 |
| Rats Indoor | $409 |
| Bedbugs | $429 |
| Cockroaches | $429 |
| Spiders Indoor | $399 |

| Fleas Indoor | $399 |
| Silverfish Indoor | $399 |
| Centipede Indoor | $399 |
| Pantry moth | $429 |
| Clothes moth | $429 |
The prices people ask for most: a carpenter ant exterminator runs $399 to $399 for a house. An exterminator for mice is $409 to $429. A bed bug exterminator starts at $429, and an exterminator for cockroaches at $429.
Wasps have their own pricing, because the work is done at the nest rather than by the room. One nest is $189, a full treatment covers every nest we find for $259, and each extra nest is $39.
Saint-Lambert is priced the same as the island. Crossing the bridge costs nothing extra.

In Saint-Lambert the Edge Belongs to Somebody Else
Saint-Lambert is a small, dense city ringed by infrastructure: the seaway and its dike along the river, the rail corridor, the Victoria Bridge approach and the highway ramps. For a city this size that is a great deal of land no resident owns.
That is what shapes our calls here, and it behaves differently from a field or a woodlot.
Infrastructure land is nobody’s garden. No one rakes it, no one cuts the brush in the fall, no one picks up what collects there. It is continuous strips of long grass, ballast and embankment, it runs alongside residential streets for kilometres, and it gives rodents shelter and a route all year.
Two practical consequences:
- Which side of the house matters. On a street running along the corridor or the dike, the elevation facing it takes pressure the opposite one does not. We start the inspection on that side, and the report says so.
- You cannot fix the source, and you cannot get it fixed. A treed strip between two subdivisions eventually gets built on. A seaway dike, a rail corridor and a bridge approach will not change, and there is no neighbouring owner to call.
What that changes about the treatment: the only lever is your own envelope, and it gets maintained rather than repaired once. On a house facing an infrastructure edge we recommend reviewing the bottom of the building every fall instead of waiting for the next problem. It costs less than an indoor treatment a year, and it is honestly the only advice that holds here.
The rest of the city is a dense, leafy older neighbourhood, with pre-war houses near the station and newer streets around them. There carpenter ants and wasps lead, on the ordinary calendar.
Mice
Call a pest exterminator for mice early rather than late. One mouse in October is a family in January, and an exterminator for one mouse is the cheapest visit on this page.
What you see: droppings along a baseboard, the size of a grain of rice, then scratching in a wall around dusk.
Why Saint-Lambert: a mouse fits through a gap the width of a pencil, and the infrastructure strips give it a starting point a few metres away. Hardened garage door weatherstripping is our number one entry point, then the dryer vent and pipe runs through an older foundation.
What fixes it: closing the bottom of the building, starting with the elevation facing the edge. Bait reduces what is already there; exclusion stops the next lot.
From $409 in a unit, $429 for a house. Perimeter control, which is the real treatment when the source is permanent, is $299.
Carpenter Ants
A carpenter ant exterminator looks for water before looking for ants. They do not eat wood, they hollow out damp wood to nest in.
What you see: big black ants indoors, sawdust under a window or a porch, and a swarm in May. Winged ants mean an established colony, not scouts.
Why Saint-Lambert: the canopy is among the heaviest on the South Shore, and the streets near the station have pre-war houses with wooden porches. The embankments and unmaintained strips also keep stumps and dead wood within flying distance.
What fixes it: treating the colony and fixing the moisture. Treating the house without looking at the trees and the back of the yard means doing it again next year.
Indoor from $399, $399 for a house. Outdoors, $129 for one visit or $327 for three.
Wasps
What you see: steady traffic at one point: a soffit, a porch, the corner of a shed, a hole in the lawn. The nest is bigger than its entrance suggests.
Why Saint-Lambert: calls peak in August. The lots are small and the houses close together, so a nest is nearly always near somewhere people walk rather than at the back of a large yard.
What fixes it: do not touch it yourself. A disturbed nest fights back, and a can from the hardware store rarely reaches the inside.
One nest is $189, a full treatment is $259.
Rats, Bed Bugs and Cockroaches
Rats are the heavy version of the same mechanism: they follow the embankments, the ballast and the infrastructure ditches, and an excavation moves a colony into the neighbouring buildings within days. They need a bigger hole than a mouse, so the entries get closed. From $409, perimeter control $299, and $230 for a single rat.
A bed bug exterminator is called after something carried them in. They live for months without feeding, so the second visit is not optional. From $429, up to $549 for a 10 ½, and $469 for a house.
An exterminator for cockroaches treats a building, not a door: roaches move through plumbing stacks and shared walls, so an exterminator for roaches covers the neighbouring units. From $429 in a unit, $499 for a restaurant.

When Saint-Lambert Pests Show Up, Month by Month
- March to May. Carpenter ants swarm once the wood thaws. Wasps start their first nests.
- June to August. Wasps peak in August, and on small lots a nest is quickly in the way.
- September to November. The big block. The first cold nights push rodents off the infrastructure strips and into heated walls, and it is the moment to review the bottom of the building.
- December to February. Quiet outside, busy inside: whatever came in during the fall breeds in a heated wall.
Why Call Us Instead of Someone Else

- We do not sell products. We do the treatment.
- Unmarked vans. No logo on the vehicles or the clothing.
- Follow-up is included. If it comes back inside the warranty, so do we, at no cost.
- Approved products. Registered for occupied homes, and no incident reported to the Quebec Poison Control Centre in 14 years.

Questions from Saint-Lambert Residents
When should I call an exterminator?
As soon as the signs repeat: noises several nights running, droppings you keep finding in the same place, sawdust under the same window. For a wasp nest near a door or a porch, right away: the colony grows until August and gets more defensive as it ages. If your lot faces the rail line or the dike, the right month for perimeter work is September, before the first cold night.
My lot backs onto the rail corridor. Can I get the strip cleared?
In practice no, and that is what makes Saint-Lambert particular. A rail corridor, a seaway dike or a bridge approach is not a neighbour’s yard you can phone about, and it will never be built on or gardened. So the source will not go away and there is nobody to wait for. The only lever is your own envelope: the bottom of the building, reviewed each fall rather than repaired once. Perimeter control is $299.
How do I choose an exterminator?
Licensed technicians, liability insurance, and a written warranty with the follow-up inside it rather than billed separately. Then three questions: is the price given before the visit or after the inspection? Does the quote cover the treatment or only the inspection? And what happens if it comes back inside the warranty?
Why call an exterminator at all?
Because the treatment is half the job and the other half is finding where they get in. Hardware store products kill what you can see, not the colony and not the route. Here the source is often off your property, so the inspection matters even more than the product does. It is included in the price, from $399 for insects and $409 for mice.
Who is the best exterminator on the South Shore?
We will not claim it is us. Compare on four things you can verify: is the price published before the visit, is the inspection included or billed separately, does the warranty include the follow-up visits, and are the technicians licensed and insured. Our prices are on this page and on our exterminator prices page. Ask everyone else the same four questions, in writing.
Do you handle raccoons and skunks?
No. We do not trap or relocate wildlife: no raccoons, skunks, squirrels, groundhogs, birds or bats. The infrastructure strips and the riverbank attract a lot of them, and it needs a licensed wildlife specialist. We treat mice, rats and insects.
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.
