    In Granby, which pest and when

    In Granby, from downtown to the Lake Boivin marshes, the pest calendar follows the weather. Here is what to watch to stay ahead of an emergency.

    Apr → Jun

    Spring

    At the thaw, carpenter ants leave the decks and woodlots, and wasp queens choose their nest sites. The right time to break a colony before summer.

    Carpenter ants waking
    Jul → Aug

    Summer

    Wasps invade decks and parks, and ticks become active in the Lake Boivin marshes and wooded strips. Outdoors, it is best to stay alert.

    Wasps and ticks
    Sep → Nov

    Fall

    The cold pushes rodents indoors. Field mice reach the homes, and the warmth of buildings and factories draws mice and rats.

    Rodents indoors
    Dec → Mar

    Winter

    In Granby, warm in the walls and the warehouses of the industrial park, mice and rats gnaw and breed all winter. We block access and clean up before damage.

    The colour of Granby

    Three traits specific to Granby

    Lake Boivin and the zoo, an active industrial park and the surrounding countryside give Granby a profile all its own. Here is what a local exterminator watches closely.

    Urban nature
    Boivin
    Lake Boivin and its marshes border Granby, rich in wildlife and vegetation

    Living right next to the marshes

    The Lake Boivin marshes, trails and woodlots shelter ticks, rats and insects that venture toward the nearby homes. We secure the entries and control the populations without taking anything away from the waterside charm.

    Industrial hub
    Factories
    Granby keeps an active industrial park, inherited from its manufacturing history

    Factories, a rodent pantry

    Docks, stores and waste areas give rats and mice permanent cover. We combine sealing, secured stations and follow-up so an infestation does not migrate toward the neighbouring shops and homes.

    Montérégie and the Eastern Townships are among the areas most affected by Lyme disease

    Lyme, very present here

    The marshes, woodlots and tall grass give ticks the habitat they seek. We show you how to clear the surroundings and protect yourself after a walk or an outing in nature.

    Structural risk

    Carpenter ants

    The dread of Granby’s big-tree bungalows and decks. We follow the trail to the parent nest, lodged in an old trunk or a damp beam, and eliminate it at the source with a bait the workers carry back to the nest. Not just a spray.
