Pest prevention is the most effective strategy to protect your property against pest intrusions in the long term. In Candiac, on the South Shore, the particular climatic conditions, the proximity of wooded areas and the density of old buildings encourage the appearance of rodents, crawling insects and other undesirables in single-family residences. Our team recently completed a complete pest prevention service for a single-storey house located in a mature residential area of Candiac, not far from the municipality of Deux-Montagnes. The owners wanted to act before autumn, a time when mice and cockroaches are looking for shelter from the cold.
Initial inspection and vulnerability assessment
Our certified technician began with a detailed inspection of the building’s exterior envelope. This step is fundamental: identifying flaws before a pest exploits them helps avoid costly infestations. The inspection covered the perimeter of the foundation, window joints, soffits, façade cladding, service passages (electrical cables, piping, ventilation), as well as the contact areas between the ground and the structure. Inside, the crawl space, attic, mechanical room and space under the sink were methodically examined. Several critical points were identified: a loose flashing joint at the roof level, a gap under the garage door greater than 6 mm, bathroom ventilation ducts without adequate screening, and cracks in the foundation mortar. These openings, even if small, are gateways for mice, cockroaches and some insect pests.
Sealing and closing work
Following the assessment, we proceeded to systematically patch each vulnerability identified. The caulking of the entry points was carried out with durable materials adapted to each type of surface: low-expansion expanding foam in the pipe penetrations, exterior acrylic sealant for joinery joints, and elastomeric sealant for foundation cracks. The ventilation ducts were covered with fine-mesh stainless steel mesh, resistant to corrosion and nibbling attempts. The garage door has been fitted with a new thick rubber bottom door seal, eliminating the gap under the board. Each intervention was carried out in compliance with the standards in force and without disturbing the comfort of the occupants.
Installation of monitoring stations and preventive follow-up
Prevention doesn’t stop at physical sealing. To ensure continuous monitoring, our team installed discreet monitoring stations at strategic points: under the kitchen sink, in the crawl space and at the electrical panel. These devices make it possible to quickly detect any attempt by rodents to intrude, without the use of pesticides in the initial phase. A quarterly follow-up plan has been put in place, including the verification of the stations, the inspection of the sealing points and an update of the recommendations according to seasonal changes. The owners have also received a list of preventive practices: waste management, storage of dry goods in airtight containers, maintenance of vegetation around the building. To discover other similar mandates carried out in the region, you can consult this prevention project as well as this case of residential caulking.
Long-term outcomes and recommendations
As a result of our intervention, the Candiac residence benefits from a reinforced envelope and an operational monitoring system. Homeowners have the peace of mind of knowing that their home is proactively protected against the South Shore’s major pest threats. An annual prevention program is much less expensive than a curative treatment in the event of a proven infestation, not to mention the potential property damage. Nova Extermination, a specialist in integrated pest management, supports residents of Candiac and the entire South Shore to protect their property throughout the year. Don’t wait for a problem to manifest itself: prevention is your best investment.
