Greenfield Park, a dynamic residential area on the South Shore that is part of the borough of Longueuil, is home to many apartment buildings whose paved driveways and common yards are particularly vulnerable to pavement ant infestations. Our team was contacted by a property manager after several tenants of a triplex reported the presence of ants in the ground and first floor apartments. The veins of workers went up from the joints of the entrance porch and bypassed the door thresholds to access the interior spaces. Neighboring Saint-Hubert and Brossard, Greenfield Park has outdoor facilities typical of mature neighbourhoods that encourage the establishment of large colonies.
Assessing the situation in a multi-unit setting
The inspection covered the entire perimeter of the building: entrance porch, cement backyard, parking lot and strip of land bordering the foundation. The technician located four separate settlements, two under the front porch, one under the concrete slab of the parking lot and a fourth in the grassy embankment on the street side. The presence of several active nests in the vicinity of a multi-unit building requires rigorous coordination to prevent the treatment of one household from stimulating migration to another. The interior inspection confirmed that the ants were using the cracks in the concrete block as corridors to circulate between the units, which explained the simultaneous complaints from several tenants. This preliminary analysis made it possible to develop a precise action plan that respects the occupants.
Coordinated intervention across the entire property
The treatment chosen for this extermination of pavement ants in Greenfield Park mobilized two technicians for a full half-day. The first step was to apply granular bait to all detected transit areas, allowing the workers to naturally distribute the insecticide within each colony. The second stage involved residual spraying around the perimeter of the foundation, the joints of the porch and the junction areas between the slab and the wall. The electrical and plumbing service penetrations through the foundation were sealed with high-density expanding foam. A diatomaceated powder was applied to the accessible concrete block cavities to create a durable mechanical barrier with no chemical residue in the dwellings. Our team in Greenfield Park ensures that each intervention meets safety standards for the residents present.

Monitoring, prevention and communication with tenants
An information sheet was provided to the manager for distribution to tenants, detailing the steps to be taken during and after processing. Recommendations included caulking cracks in interior walls, eliminating any accessible food sources, and repairing deteriorated paving joints. For complete seasonal protection of this type of property, an annual outdoor insect treatment is a wise investment. A control visit was carried out one month after the intervention to validate the disappearance of the colonies and answer the residents’ questions.
