Distribution warehouses, logistics centers, and long-term storage buildings can develop infestations that are resistant to spot treatments. Complete fumigation, rarer but more definitive, allows you to start again on a healthy basis.
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.
Who is this service for?
Distributors and logisticians. Food distribution centres, raw material warehouses, processing workshops, sometimes buildings being reopened after prolonged closure.

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: Warehouse Fumigation
What is warehouse fumigation and when is it needed?
Warehouse fumigation deals with large storage volumes where foodstuff or pest insects threaten goods and stocks. Nova Extermination seals the building or sections concerned and diffuses a registered fumigant that reaches pallets, racks and hard-to-reach corners. This service is intended for distribution centres and warehouses on the South Shore, particularly in Boucherville and Longueuil.
Can you fumigate a warehouse containing foodstuffs?
Yes, as long as you follow the food-specific instructions, which Nova Extermination establishes according to the nature of the products stored. Some stocks must be protected, isolated or removed, and complete ventilation is confirmed before any return to service. Our certified technicians document the intervention for your traceability and sanitation requirements.
How do you manage logistics and disruption of warehousing operations?
We coordinate the response with your team to plan for the shutdown of activities, securing access, and evacuating staff during treatment. The duration of immobilization depends on the fumigant, the volume and the airtightness of the building, and is communicated to you at the time of the evaluation. Nova Extermination aims to minimize the impact on your supply chain in Montérégie.
What pests can be treated with warehouse fumigation?
It targets insects in stored foodstuffs, beetles, moths and other organisms that infest dry products, textiles or raw materials. The fumigant penetrates the inside of packages and cavities where surface treatments are ineffective. Our technicians determine the appropriate registered product after identifying the infestation on site.
What is the cost of warehouse fumigation?
The price is established on the basis of an evaluation, depending on the extent of the situation, the volume of the warehouse, the nature of the stocks and the tightness of the building. Nova Extermination inspects your facilities on the South Shore before presenting you with a suitable proposal. This paid professional service is carried out by an RBQ and CNESST certified team.
Do you guarantee that the warehouse will be pest-free after treatment?
We apply recognized approved processes, but the results are evaluated on a case-by-case basis depending on the extent of the infestation, the comings and goings of goods and the condition of the premises. Nova Extermination recommends follow-up and preventive measures rather than a total warranty, which is impossible in an active storage environment. Reintroduction through incoming stocks is always a factor to be monitored.
