Saint-Eustache Exterminator

Saint-Eustache pairs its famous heritage Vieux-Saint-Eustache, on the Mille Îles and du Chêne rivers, with large residential neighbourhoods, an industrial park and farmland. This mix of old stock, riverbanks and job zones mostly draws carpenter ants, shore rats, cockroaches and mice. Our Saint-Eustache exterminator treats at the source, from the old-core apartment to the neighbourhood home.

    Saint-Eustache through the seasons

    The pest changes with the calendar

    What comes back in Saint-Eustache, from the old core to the neighbourhoods, across the year.

    April to June

    The two-river flood dislodges rats

    The spring rise of the Mille Îles and du Chêne rivers drives Norway rats from the banks toward the Vieux-Saint-Eustache basements and waterfront homes.

    Rats rising
    July to August

    Carpenter ants in the old stock

    The damp old wood of Vieux-Saint-Eustache draws carpenter ants, while wasps nest under the cornices of the heritage core.

    Insects rising
    September to November

    Mice and cockroaches seek warmth

    Cool air pushes neighbourhood and farmland mice toward the homes, while old-core cockroaches reach the heated apartments.

    Rodents and cockroaches rising
    December to March

    The dense old core stays warm

    Winter freezes the insects outside, but cockroaches and mice already settled in the adjoining Vieux-Saint-Eustache apartments keep breeding through shared walls.

    What shapes our work here

    Three realities specific to Saint-Eustache that guide our method.

    The heritage
    1837
    old historic core and mill

    The old stock lets pests in

    Stone foundations, old walls and period wood of Vieux-Saint-Eustache offer countless passages to rodents and insects. We seal the heritage stock without spoiling it.

    The water brings the rats

    The Mille Îles and du Chêne river banks form a reservoir of Norway rats that reach the core and waterfront homes. We treat building access as much as the exterior.

    The warehouses draw the rats

    The industrial park and the Highway 640 shops offer Norway rats containers and docks. We close access and secure the building perimeter.
