Richelieu is a town in the Montérégie region established on the Richelieu River, an immediate neighbour of Chambly, whose residential fabric is accompanied by a few local businesses that animate local life. It was in a family restaurant in Richelieu, whose loyal customers had appreciated the home cooking and warm atmosphere for years, that the management was confronted with a delicate situation: the discovery of mouse droppings in the professional kitchen during a routine check before the opening of the lunch service. The presence of service lanes behind the buildings and the proximity of the wooded surroundings of the Richelieu River create conditions conducive to rodent migration. The manager of the establishment contacted our team of exterminators in Richelieu that morning and we scheduled an emergency inspection for the evening, after the department closed.
Emergency assessment of the professional kitchen
The inspection was conducted after the restaurant closed to maintain confidentiality and not affect service. Technicians systematically inspected the kitchen, service hallway, dry food storage, cold room, laundry area, waste room and staff changing room. The ultraviolet lamp technique revealed active urinary tracks connecting the dry storage room to the kitchen via the base of a ventilation duct whose wall grille was partially detached. Nests were located in the insulated partition behind the convection oven and in the food cartons piled directly on the floor of the storeroom. The rodent infestation inspection also detected two unsealed openings around the kitchen’s stainless steel pipes, with a diameter sufficient to let young mice through. The municipal inspectorate received a copy of the preliminary report within forty-eight hours, allowing the establishment to start a dialogue with the health authorities and to demonstrate the responsiveness of the establishment.
Intensive processing in accordance with food regulations
In any food service establishment, the treatment protocol must comply with strict regulatory restrictions regarding pesticides in food preparation and handling areas. Our mouse extermination plan in Richelieu was therefore based exclusively on quick-release mechanical traps installed in closed safety boxes, placed under kitchen equipment, in the storeroom and in the service corridor areas. The defective ventilation grilles were temporarily sealed with stainless steel nets during the active treatment phase to limit the circulation of rodents between the areas. Outside, a perimeter of secure bait stations has been established around the building, with a particular focus on the goods receiving area and the waste room. A first check forty-eight hours after the installation of the devices confirmed active captures, and the positions were adjusted accordingly. Our rat extermination project in a South Shore restaurant illustrates a comparable approach in a similar restaurant context.
Decontamination, Restoration and Ongoing Prevention
After confirmation of the complete elimination of the mice, a thorough rodent decontamination was carried out in all affected areas. This process included vacuuming feces and organic matter with a HEPA filter vacuum, disinfecting all contaminated surfaces with a virucidal product approved for food environments, replacing soiled thermal insulation behind the convection oven, and disinfecting the accessible ventilation duct. All entry points were sealed: the ventilation grilles were replaced with stainless steel models with a mesh size of less than one centimetre, the openings around the pipes were sealed with fire-resistant sealant reinforced with steel wool, and the bottom of the delivery door was fitted with a new anti-intrusion metal seal. The Richelieu restaurant was able to maintain its health accreditation and resume its normal service without any visible interruption to customers. The directorate has integrated a pest prevention plan into its monthly maintenance program, including preventive control visits and a surveillance log available to public health inspectors. This proactive approach is the best guarantee for a restaurant that wants to protect its reputation and maintain the trust of its customers over the long term.
