Our extermination services in Montreal
Our certified technicians provide residential and commercial pest control for ten types of pests in houses, plexes, businesses and warehouses across Greater Montreal. Each extermination service has its own page, with the method specific to that pest.
01Cockroach exterminator
+ details
Cockroaches (also called roaches) hide in the warm, damp areas of kitchens and bathrooms. Our cockroach exterminator eliminates them with gel bait, in 2 to 3 treatments depending on the extent of the infestation.
02Bed bug exterminator
+ details
Bed bugs spread from one unit to the next through the shared walls of plexes. Our bed bug extermination service starts with an inspection of the mattress, furniture and baseboards.
03Mouse exterminator
+ details
Mice get in through very small openings around pipes and house foundations. Mouse extermination combines traps, tamper-resistant bait stations and sealing of entry points.
04Rat exterminator
+ details
Rats damage electrical wiring and contaminate food. Our rat exterminator locates their runways, then installs tamper-resistant stations and puts exclusion measures in place.
05Field mouse extermination
+ details
Field mice move into garages and house basements in the fall. See our field mouse extermination service in Montreal.
06Ant exterminator
+ details
Ants keep coming back as long as the colony is active. Our ant extermination service treats the nest with baits that worker ants carry back to the colony, for lasting results.
07Carpenter ant exterminator
+ details
Carpenter ants dig galleries in the damp wood of balconies and framing. Our carpenter ant exterminator locates the colony and the damage inside walls, using a thermal camera when needed.
08Wasp and hornet exterminator
+ details
A wasp or hornet nest under a balcony, on a roof or in a shed is removed the same day in an emergency. Our wasp exterminator treats the nest safely for your family.
09Spider extermination
+ details
Spiders follow the insects they feed on, near windows and in basements. Our spider exterminator applies a targeted residual treatment around the house and in their hunting areas.
10House centipede extermination
+ details
House centipedes seek out the moisture of basements and bathrooms. Our page on house centipede extermination explains the inspection and treatment.
Our 5-step extermination method
Every professional pest control visit follows integrated pest management (IPM): understand the infestation before treating, then keep pests from coming back.
01Site inspection and thermal camera
▾
The inspection spots signs of infestation, entry points and insect or rodent nests. Depending on the situation, the thermal camera reveals pest activity hidden inside walls.
02Identifying the pest and the species
▾
The species and the extent of the infestation determine the treatment, the number of visits and the price. A mouse and a rat, for example, call for different traps and stations.
03Targeted treatment: baits, traps, exclusion
▾
Depending on the case, the treatment plan combines gel bait, traps, tamper-resistant stations, targeted residual treatment and exclusion measures. We treat active areas rather than the whole home: less product, more effective treatment.
04Products registered by Health Canada
▾
When an insecticide is needed, we only apply products registered by Health Canada, following the label and current standards. The technician explains the precautions for children and pets before the treatment.
05Prevention, follow-up and written warranty
▾
After the treatment, our exterminators give you prevention tips against reinfestation: sealing entry points, food storage, maintenance. The warranty period and the pests covered are written on your invoice.

Exterminator for homes, businesses and warehouses
Residential extermination: condos and plexes
We work in houses, condos, duplexes and triplexes as well as apartment buildings, where cockroaches and bed bugs travel from one unit to another. Tenants, landlords and property managers can find out who is responsible for treatment in our article on extermination in an apartment building.
Commercial extermination and MAPAQ standards
We treat offices and businesses; in restaurants and food businesses, our work strictly follows the standards of the MAPAQ, Quebec’s food inspection authority. For rodents, see our article on rats in Montreal restaurants.
Industrial extermination under contract
For warehouses and industrial sites, pest management is often handled under a maintenance contract. The treatment plan adapts to the building, the goods stored and the rodents or insect pests present.
24/7 emergency service, 365 days a year
Our 24/7 emergency line answers at 514 501-2076, weekends and holidays included. In an emergency, we respond the same day; scheduled visits take place within 24 to 72 hours.
Written warranty on the invoice
Every treatment comes with a written warranty, right on your invoice. The warranty period varies by pest and treatment: it is spelled out in black and white.
Fixed price and payment plans
The calculator shows the fixed price of your extermination in about 60 seconds, with no sign-up. Quotes are free, prices have no hidden fees, and payment plans spread out the cost.
Thermal camera for hidden nests
The thermal camera picks up the heat of rodent nests and carpenter ant colonies inside walls, so the targeted treatment goes straight to the source of the infestation.
Unmarked vehicles for discretion
Our unmarked vehicles keep every visit discreet in front of your neighbours, tenants or customers.
FAQ: exterminator in Montreal
How much does an exterminator cost in Montreal?
▾
Most residential treatments cost $250 to $700 per treatment. The overall range is $250 to $1,500 depending on the pest, the area and the extent of the infestation. Bed bugs and carpenter ants can reach the top of the range (up to $1,500 and $1,250). Our online calculator gives you a fixed price in about 60 seconds; payment plans are available.
How quickly can an exterminator come in Montreal?
▾
In an emergency, we come the same day: a wasp nest near a door, an acute bed bug or cockroach infestation, rats in the home. For a scheduled visit, allow 24 to 72 hours. Our emergency service answers 24 hours a day, 7 days a week, 365 days a year, everywhere in Greater Montreal.
What does the SOS Extermination written warranty include?
▾
The written warranty appears directly on your invoice. It specifies the coverage period (which varies by pest and treatment), the pests covered and the conditions for a return visit. With any exterminator, ask for these details in writing, along with a commitment to come back at no charge if the infestation returns during the warranty period.
Are your exterminators certified?
▾
Yes. SOS Extermination works with certified technicians. In Quebec, applying pesticides for pest control requires a permit for the company and a CD5 certificate for the applicator, or supervision by a certificate holder. Our methods favour inspection, exclusion and targeted treatment before any insecticide.
Are the treatments safe for children and pets?
▾
Yes, when you follow the technician’s instructions. Our Health Canada-registered products are applied according to the label, as a targeted treatment on infested areas. Gel bait goes into cracks, out of reach; tamper-resistant stations prevent any contact. The technician tells you how long to keep children and pets out of the treated rooms.
Can I get rid of pests myself?
▾
A trap or a hardware-store product sometimes takes care of a lone mouse or a few ants. An established bed bug, cockroach or carpenter ant infestation needs professional treatment: identifying the species, finding the nest and treating hidden areas. Bug bombs often push pests into neighbouring rooms instead of eliminating them.
Which areas of Greater Montreal do you serve?
▾
We serve ten areas on the island of Montreal, mainly boroughs in the east and centre, ten South Shore areas (from Longueuil to Châteauguay) and ten North Shore cities (from Laval to Saint-Eustache). Our 24/7 emergency service has the same number everywhere. For another area, call us: we will confirm the response time.

What our clients say about us
Je gère plusieurs immeubles et j'ai trouvé SOS Extermination via leur calculateur de prix en ligne. Super pratique. J'avais une grosse urgence de fourmis charpentières dans un bloc sur le Plateau-Mont-Royal. Je les ai appelés et en même pas 24h, Oussama était sur place avec sa caméra thermique. C'était impressionnant de voir tous les nids satellites cachés dans les murs ! Bonne job les gars, merci
Mariam HajajVerified Google reviewOn a eu une grosse invasion de fourmis charpentières dans mon triplex à Rosemont dernièrement. Il y en avait vraiment partout, même des grosses avec des ailes qui volaient ! J'ai appelé l'équipe de SOS Extermination et honnêtement, ils ont réglé le problème comme par magie. Il n'y a plus aucune trace. Un super bon service, je les recommande sans hésiter.
Gabrielle AllaireVerified Google reviewMy neighbour recommended Sos-extermination for our carpenter ant problem here in the West Island. Honestly I'm so glad I listened to her! We were freaking out but they passed by super fast to do the treatment. Since then there hasnt been a single trace of them, they completly disappeared.
