    The cycle of the year

    In Saint-Hyacinthe, which critter and when

    In Saint-Hyacinthe, from downtown to the rangs of Les Maskoutains, the pest calendar follows the weather and farm work. Here is what to watch for to get ahead of the emergency.

    Apr → Jun

    Spring

    At the thaw, carpenter ants set out again in the old buildings and woods, wasp queens start their nests, and humidity brings earwigs and sow bugs back near the foundations. The right time to seal and treat early.

    Carpenter ants and moisture critters
    Jul → Aug

    Summer

    Wasps settle around decks and plants, and ticks move into the tall grass of the rangs and orchards. In town as in the fields, we stay vigilant.

    Wasps and ticks
    Sep → Nov

    Fall

    Harvests over, wood mice and field mice move into houses and plants, followed by cluster flies on sunny walls. Rodents covet the food storage.

    Field rodents
    Dec → Mar

    Winter

    Snug in the walls, plants and silos, mice and rats gnaw and breed all winter. We block access and sanitize before the damage.

    Rodents in the walls
    The Maskoutain profile

    Three realities specific to Saint-Hyacinthe

    The agri-food capital, the Yamaska River and the vast countryside of Les Maskoutains give Saint-Hyacinthe a unique profile. Here is what an exterminator from here keeps a close eye on.

    Agri-food capital
    Plants
    Saint-Hyacinthe concentrates leading processing plants and food industries

    Where things are processed, rodents prowl

    Storage areas, production areas and loading docks attract rats, mice and cockroaches, in an environment where health standards are strict. We combine inspection, sealing and rigorous follow-up to protect production and neighbouring buildings.

    Yamaska River
    Humidity
    The Yamaska runs through the city, with old buildings and damp basements

    Humidity brings basement critters

    Cool basements and damp foundations favour earwigs, sow bugs, ants and mice. We treat the cause as much as the insect, by drying damp spots and sealing entry points.

    Montérégie is among the regions most affected by Lyme disease in Quebec

    Lyme disease, all the way into the rangs

    The tall grass of the rangs, orchards and woods gives ticks the habitat they look for. We show you how to clear the surroundings and protect yourself when you come back from the fields.
