    In Mercier, which critter and when

    In Mercier, from the new neighbourhoods to the rangs, the pest calendar follows the weather and the harvests. Here’s what to watch to stay ahead of an emergency.

    Apr → Jun

    Spring

    As soon as it thaws in Mercier, carpenter ants wake along the Châteauguay River, while wasp queens are already scouting the spot for their future nest. It’s the ideal time to act early and break a colony before it grows.

    Jul → Aug

    Summer

    In midsummer in Mercier, wasps and hornets settle along the Châteauguay River while ticks gain ground in the woods. We target the nests early to keep the outdoor spaces safe.

    Wasps and ticks
    Sep → Nov

    Fall

    When the cold sets in in Mercier, rodents leave the fields along the Châteauguay River for your walls, along with fall flies looking to overwinter indoors.

    Dec → Mar

    Winter

    During winter in Mercier, rodents and critters stay tucked in the heated structures and multiply there. We block every entry point and clean up before spring.

    The Mercier profile

    Three realities unique to Mercier

    A growing suburb set on the lands of Roussillon and bordered by the Châteauguay River gives Mercier a profile all its own. Here’s what a local exterminator watches closely.

    Growing suburb
    New
    Mercier has many recent neighbourhoods built near the fields

    Construction sites drive out rodents

    In Mercier, when a neighbourhood rises on former fields, voles and field mice take refuge in the new houses. We seal the access points of the buildings before they settle into the walls.

    Rangs
    Mercier keeps vast farmland around its urban core

    At harvest, the voles move in

    In Mercier, when the fields are cut, voles and field mice look for warm shelter and rush toward the houses and farms. We seal the access points before the frosts to cut off their entry.

    In Mercier, the edges of the Châteauguay, the wooded strips and the tall grass give ticks the habitat they seek. We show you how to clear the surroundings and protect yourself after an outing.

    Field mice and voles

    From new neighbourhoods near the fields to the farms, as soon as the harvests are cut, they rush toward the houses. We spot the entries, seal them and install secured stations to cut off the flow rather than chase each one. The key is to block before the frosts.
