A Mont-Royal exterminator costs $429 for bed bugs, $409 for mice, and $399 for carpenter ants and other insects. A wasp nest is $189. These are prices, not ranges, and 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.
This page is about the Town of Mount Royal, the linked town ringed by the rail line, and not about Plateau Mont-Royal, which is a separate borough. The two are searched with almost the same words and have nothing in common.

The prices people ask for most: a bed bug exterminator starts at $429. An exterminator for mice runs $409 to $429 for a house. A carpenter ant exterminator starts at $399, and an exterminator for cockroaches is $429 in a unit.
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.

In Mont-Royal the Entry Point Is Often Under the House
Mont-Royal was laid out in one go in 1912 and built mostly between the 1920s and the 1950s: single family houses on large lots, under one of the densest tree canopies on the island. That combination produces something we do not see anywhere else.
The mature trees the town protects have roots, and those roots share the lot with a drain line installed eighty or a hundred years ago. A root finds a joint, opens it, and the pipe cracks. The result is not only a plumbing problem: it is a door.
A rat coming up the drain needs no visible opening at all. It travels the line from the municipal sewer and comes out at a floor drain with no backflow valve, a basement fixture, sometimes a basement toilet nobody uses. That is why we get a call here that we rarely get anywhere else: the house is sealed tight and the owner cannot work out how.
How to recognise it:
- Activity starts in the basement and works up, instead of starting at the garage or the attic.
- Nothing outside. A walk around the house shows no hole, no burrow, no worn run through the grass.
- A smell or a backup that keeps returning in the same room, or a floor drain that smells of sewer in dry weather.
What we do about it: we find it and we tell you in writing. Repairing the drain is a plumber’s job, and a camera inspection of the line settles the question in an hour. On our side we treat what is already in and close everything else, because a house with a way in from below almost always has others up top.
The canopy works above ground too, and there it is carpenter ants: a mature branch touching the roof is a bridge, and an old stump at the back of the lot is a parent colony. Both mechanisms come from the same trees, one through the roots and one through the branches.
Rats and 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: for rats, droppings clearly bigger than a grain of rice, noise in a basement ceiling, a drain that smells. For mice, droppings along a baseboard and scratching inside a wall around dusk.
Why Mont-Royal: the drain route described above, and for mice the ordinary openings of an older house, meaning hardened weatherstripping at an attached garage door and pipe penetrations in the foundation wall.
What fixes it: inspection before bait. Laying bait in a basement whose line is cracked brings the number down for a few weeks, then the next ones come up the same way.
Mice from $409 in a unit, $429 for a house, perimeter control $299. Rats from $409, perimeter $299, and $230 for a single rat.
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 beam, and a swarm in May. Winged ants mean an established colony, not scouts.
Why Mont-Royal: the canopy. A branch touching the roof gives direct access that never goes near the ground, and a stump or an old tree at the back of the lot holds the parent colony that sends satellites into the first damp wood in the house.
What fixes it: treating the colony, fixing the moisture and clearing the roof. Treating the house without looking at the trees means doing it again next year.
Indoor from $399, $399 for a house. Outdoors, $129 for one visit or $327 for three.
Bed Bugs and Cockroaches
A bed bug exterminator is almost always called after something carried them in: travel, a used piece of furniture, a student room coming home. You see bites in a line on skin left uncovered at night, then small dark spots at the mattress seam. 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 sees fewer cases here than in the apartment districts, because roaches spread through shared walls and plumbing stacks and this is a town of detached houses. When they do turn up they arrived in cardboard and stayed put, which makes an exterminator for roaches a one-house job rather than a building one. From $429 in a unit, $469 for a house.
Wasps, Silverfish and Spiders
Wasps peak in August. You see steady traffic at one point: a soffit, the corner of a shed, a hole in the lawn. The lots are big and landscaped, which gives ground nests as well as soffit nests, and a cedar hedge hides one until somebody trims it. Do not touch it yourself. One nest is $189, a full treatment is $259.
Silverfish and spiders follow moisture rather than food. A finished basement on a slab that was never sealed holds them from June to September. From $399, $399 for a house.

When Mont-Royal Pests Show Up, Month by Month
- March to May. Carpenter ants swarm once the wood thaws. Wasps start their first nests, still small.
- June to August. Wasps peak in August, and a trimmed hedge turns one up.
- September to November. The first cold nights push mice indoors.
- December to February. Rat calls do not follow the season, because the sewer does not freeze.

Questions from Mont-Royal Residents
How much does a mouse exterminator cost?
$409 in a 4 ½, $429 for a house, inspection included. Perimeter control, which is what stops it coming back the following fall, is $299. These are published prices, not ranges, and there is no separate inspection fee.
My house is sealed and I still have rats. How?
This is the most common question we get in the Town of Mount Royal, and the answer is almost always under your feet. The houses here date from the 1920s to the 1950s and the drain line is the same age, running under mature trees whose roots eventually crack a joint. A rat then travels up from the sewer and comes out at a floor drain with no backflow valve or a basement fixture, without ever needing a visible opening. The signs: activity starts in the basement, nothing outside, and sometimes a sewer smell in the same room. A camera inspection of the line settles it, and the repair is a plumber’s job.
Does this page cover Plateau Mont-Royal?
No. This page covers the Town of Mount Royal, the linked town ringed by the rail line. Plateau Mont-Royal is a separate borough on the other side of the mountain, built of plexes and rental units rather than detached houses, and the work there looks nothing like this. We serve both. If you are on the Plateau, our Montreal page is the right one.
What is the hardest pest to get rid of?
Bed bugs. They hide in cracks a millimetre wide, live for months without feeding, and their eggs survive the first treatment, which is why the second visit is required rather than optional. Rats are the hardest to keep out here for a different reason: if they are coming up a cracked drain line, no amount of exterior sealing touches the route. Carpenter ants are easy to kill and hard to finish, because the parent colony is usually in a tree rather than in the house.
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?
Do you handle skunks and raccoons?
No. We do not trap or relocate wildlife: no skunks, raccoons, squirrels, groundhogs, birds or bats. That needs a licensed wildlife specialist, and the large wooded lots here attract them. We treat mice, rats and insects, and that is all we do.
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.
