    Season after season

    In Cowansville, which critter and when

    From Davignon to the Sutton ridges, the seasons dictate which critter shows up. Here is the guide to get ahead of the emergency.

    Apr → Jun

    Spring

    The spring awakening kicks off the season. Carpenter ants looking for soft wood, wasp queens scouting around houses, anthills expanding fast. Acting early saves you a lot later.

    Carpenter ants waking
    Jul → Aug

    Summer

    Ripening orchards and vineyards draw wasps and hornets in numbers, while ticks are active, from spring to fall, on the region’s trails, from Sutton to Mont Pinacle. The pressure peaks.

    Wasps and ticks
    Sep → Nov

    Fall

    With the grape harvest and crops finished, wildlife looks for cover. Rodents from the orchards and fields move into homes, followed by flies that cluster on sunny walls.

    Fall rodents
    Dec → Mar

    Winter

    Closed chalets and heated walls delight mice, which find warmth and shelter there. The right time to flush out forgotten access points and sanitize thoroughly.

    What makes Cowansville

    Three realities specific to Cowansville

    The wine route, the mountains of the Townships and the resort lakes give Cowansville a unique profile. Here is what a local exterminator watches closely.

    Public health · Ticks
    South
    Estrie, including Brome-Missisquoi, is part of the Lyme disease endemic zone in Québec (INSPQ, June 2026)

    Lyme, well established in the Townships

    Sutton trails, the shores of Lac Brome, the woods around Lac Davignon: ticks that carry Lyme disease are at home in the region. We show you how to manage vegetation and protect yourself around the house and after a hike.

    Wine route
    Orchards
    The vineyards and orchards of Dunham and Bromont draw wasps and hornets in large numbers at the end of summer

    When the fruit ripens, the wasps arrive

    The sugar in grapes and apples turns the end of summer into a feast for wasps. Around terraces, pools and wine cellars, we locate and neutralize nests before they spoil your evenings.

    Resort area
    Lakes
    The chalets of Lac-Brome, Sutton and Bromont, often empty in the off-season, become perfect shelters

    The closed chalet, a refuge for mice

    A seasonal home left empty for weeks quickly becomes a cozy nest for mice and carpenter ants, sheltered and warm in the wood. We secure the access points before closing up and sanitize on your return.

    Structural risk

    Carpenter ants

    Chalets in Lac-Brome and homes along the Davignon bear the brunt. We follow the column of workers to the main nest, hidden in a piece of damp wood, and wipe it out at the source with a self-spreading bait. No more gnawing at the framing.
