    On the South Shore, what kind of bug and when?

    On the South Shore, from the towers of Brossard to the fields of Roussillon, the pest calendar is dictated by the weather, water, and crops. Here’s what to watch for to stay one step ahead of any emergencies.

    Apr → Jun

    Spring

    As soon as the ground thaws on the South Shore, carpenter bees emerge from Longueuil to Roussillon, while wasp queens are already scouting out the site of their future nest. This is the ideal time to take early action and break up a colony before it grows.

    The Carpenters’ Awakening
    July → August

    Summer

    In the middle of summer on the South Shore, wasps and hornets settle in from Longueuil to Roussillon, while ticks are gaining ground in the woods. We target the nests early to keep outdoor spaces safe.

    Wasps and Ticks
    Sept → Nov

    Fall

    When the cold sets in on the South Shore, rodents leave the fields of Longueuil and Roussillon and head for your walls, accompanied by fall flies looking to spend the winter indoors.

    Rodents in the Warm
    Dec → Mar

    Winter

    During the winter on the South Shore, rodents and other pests remain hidden in heated buildings and multiply there. We seal off every entry point and clean the premises before spring.

    Three realities specific to the South Shore

    A region that transitions from apartment complexes to riverside villages and farmland presents the South Shore with a wide variety of pest challenges. Here’s what a local pest control operator keeps a close eye on.

    Urban density
    Plex
    The Longueuil metropolitan area is home to high-rises, apartment complexes, and multi-unit housing

    In apartment buildings, pests migrate

    When apartments are right next to each other, mice, cockroaches, and bedbugs can move from one apartment to another through the walls and utility shafts. We treat the entire building to stop their spread—not just a single unit.

    Riverfront
    River
    The South Shore runs along the St. Lawrence River for dozens of kilometers

    Near the river, rats and woodlice

    Riverbanks, industrial areas, and damp basements attract rats and other pests that thrive in damp conditions. We inspect the areas surrounding properties along the river and tackle the dampness that feeds them.

    The Montérégie region is one of the areas most affected by Lyme disease in Quebec

    Lyme disease is present throughout the South Shore

    Wooded areas, riverbanks, and tall grass provide the habitat ticks seek, from Mont Saint-Bruno to the Richelieu Valley. We offer advice on prevention and clearing these areas.

    The most common

    Mice and field mice

    From urban apartment complexes to new homes near the fields, they always find a way in anywhere on the South Shore. We identify entry points, seal them off, and install security stations to cut off their access rather than chase after each one. In multi-unit buildings, we consider the entire building.
