In exceptional cases of massive infestation (multifocus bed bugs, resistant cockroaches, mealworms in insulation), the complete fumigation of a residence may be justified. This is a rare procedure in Quebec but sometimes required when conventional treatments fail.
Nova Extermination offers this service with technicians holding the Restricted Application Permit (RAP) issued by Health Canada, in accordance with the applicable regulatory requirements. License RBQ 5734 75930 01. Service offered on the South Shore of Montreal and beyond as needed.

Questions
How long does it take to plan this fumigation?
For urgent cases (imminent export, confirmed active infestation), 48 to 72 hours. For recurring contracts (seasonal silos, planned batches), year-round planning.
Are there chemical residues in the goods after processing?
No, after ventilation and residue measurement, the goods are certified below the regulatory thresholds (0.1 ppm for phosphine in food grains, for example). The certificate documents this measurement.
What gas do you use and why?
Phosphine as standard, methyl bromide for some demanding countries. The choice depends on the goods, the destination country and the available time. We validate with you before intervention.
Is the certificate valid for my customs export?
Yes, our certificates meet ISPM 15 requirements and are accepted by major customs agencies and international buyers. If your buyer has specific requirements, please let us know: we will adapt the documentation.
How do I get a quote for this intervention?
Inspection after a brief preliminary audit of the volume to be processed and the documentary requirements (export, buyer, authority). The estimate is written, detailed and fixed before any work begins.
What are the risks for my employees or for the neighbourhood?
The safety protocol eliminates risks when followed: watertight containment, monitoring probes, controlled ventilation, measurement of residues before reoccupation. For urban areas, coordination with local authorities and notification of neighbours.

Frequently Asked Questions: Residential Fumigation
What does residential fumigation consist of at Nova Extermination on the South Shore of Montreal?
Residential fumigation consists of treating an entire home with a registered fumigant that penetrates walls, floors and cavities where insects or pests hide. At Nova Extermination, an RBQ and CNESST certified technician seals the accesses, applies the process according to the product’s technical sheet, then proceeds with ventilation and testing before the occupants are reintegrated. This treatment serves residences in Longueuil, Brossard and the entire Montérégie region.
How long should we leave the house during a fumigation?
The duration of vacancy generally varies from 24 to 72 hours depending on the fumigant used, the extent of the infestation and the volume of the residence. Nova Extermination establishes a specific schedule during the evaluation and confirms the reinstatement only after the concentration readings attest that the air has returned to safety. We plan everything to minimize inconvenience to your family.
Is residential fumigation safe for my family and pets?
Yes, when it is carried out by certified professionals who respect ventilation and reintegration protocols. Nova Extermination uses approved products, secures access during treatment and checks residual concentrations before your return. We also provide you with clear instructions regarding food, plants and pets.
How should we prepare our home before treatment?
We provide you with a detailed list of preparations: removing or hermetic packaging certain foods, medications and plants, unplugging devices if necessary and clearing access to the areas to be treated. Good preparation, supervised by our technician in Boucherville or Saint-Hubert, ensures the efficiency of the process and the safety of the premises. Our team answers all your questions before the intervention.
What is the price of residential fumigation?
The price is established on the basis of an evaluation, depending on the extent of the situation, the surface area of the residence, the type of pest and the fumigant required. Nova Extermination first conducts an inspection of the premises on the South Shore in order to present you with a proposal adapted to your case. This is a professional paid service performed by certified technicians.
Do you offer a warranty on residential fumigation?
We apply approved processes and products that are known for their effectiveness, but the results are evaluated on a case-by-case basis depending on the extent of the infestation and the condition of the building. Nova Extermination honestly informs you of realistic expectations and preventive measures to adopt after treatment. No total guarantee can be promised, because each situation remains unique.
