Saint-Philippe, a fast-growing city on the South Shore, is home to an active commercial sector along Highway 640, not far from Sainte-Julie. It was in a retail store specializing in the sale of bulk food, located in a single-storey commercial building, that the owner discovered traces of gnawing on food packaging stored in the rear storeroom one morning. The presence of mice in a food establishment is a serious violation of provincial health regulations and can result in severe penalties or even temporary closure by public health inspectors. The situation required a rapid, discreet response that was fully compliant with the requirements of the food environment. The owner contacted our Quebec extermination company as soon as it opened and our technicians were on site in less than four hours.
Inspection in the context of food sales
The inspection was carried out before the opening of the business so as not to disrupt the activities and to preserve the confidentiality of the process. The technicians reviewed all the risk areas: dry storage, goods reception area, back counter, employee bathroom, mechanical room and the exterior perimeter of the building, including the loading area at the back. A thorough rodent infestation inspection was conducted with ultraviolet light to detect urinary tracts not visible to the naked eye. Active traces were found along the walls of the storeroom, behind the metal storage shelves, and under the wooden pallets on the floor. Two active nests were located in empty packing boxes piled up in a corner of the storeroom. The main entry point identified was a settlement crack at the joint between the concrete slab and the rear wall of the room, about one centimetre wide at its top. A second access was under the loading door, which had a cracked rubber seal and left a space for use by the smallest rodents. Contaminated or potentially contaminated goods have been identified and quarantined for destruction in accordance with applicable regulatory procedures.
Treatment adapted to food health standards
In a food retail environment, the use of indoor rodenticides is very strictly regulated. Our mouse extermination plan in Saint-Philippe therefore favored high-precision mechanical traps installed in fully enclosed housings, positioned in areas inaccessible to staff and customers: behind the fixed shelves of the storeroom, under household appliances and in restricted access areas. These devices have the advantage of leaving no dead bodies accessible and eliminating any risk of cross-contamination. Outside the building, a perimeter of secure, impact-resistant bait stations was set up along the foundation to intercept rodents that had not yet entered the building. A schedule of daily verification for the first week, followed by a weekly check for one month, ensured a rigorous and traceable follow-up in accordance with the requirements of health inspections.

Caulking, decontamination and regulatory compliance
Once the rodent activity was completely extinguished, the technicians proceeded with rigorous caulking of all identified entry points . The main crack in the foundation was filled with a high-strength epoxy mortar and then covered with a stainless steel plate screwed directly into the concrete. A new dense brush aluminum door bottom seal was installed on the loading door to permanently eliminate secondary access. The cable and pipe passages through the walls of the reserve were sealed with steel wool embedded in silicone putty. Rodent decontamination included aspiration of faeces with a HEPA device, complete disinfection of contaminated surfaces with a virucidal agent registered for use in food media, and disposal of soiled porous materials. The owner received a comprehensive response report, which can be presented upon inspection, as well as a weekly clean-up protocol for the reserve and recommendations on stock organization to reduce areas suitable for nest establishment. Quarterly preventive inspections have been planned to maintain the health compliance of the trade in the long term.
