    The season cycle

    In Saint-Jean, which critter and when

    In the Haut-Richelieu, from the Richelieu to Lake Champlain, 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 hits 4 degrees, ticks get active and carpenter ants emerge in the old buildings of the two banks, while the freeze-thaw cracks open new entries. The first black flies arrive near the water. The right time to seal and treat early.

    Carpenter ants and ticks
    Jul → Aug

    Summer

    Mosquitoes explode near the Richelieu, Lake Champlain and the marshes, and wasps settle around the terraces and orchards. Ticks stay very active on Mont Saint-Grégoire and the woods.

    Mosquitoes and wasps
    Sep → Nov

    Fall

    Harvests done, voles, field voles and field mice reach the homes and farms, followed by Asian lady beetles and fall flies on the sunlit walls.

    Field rodents
    Dec → Mar

    Winter

    Warm inside the walls, silos and old basements, mice and rats gnaw and breed all winter. We block access and sanitize before the damage.

    Rodents in the walls
    The Haut-Richelieu profile

    Three realities unique to Saint-Jean and its region

    Two major waterways, intensive agriculture and a mountain covered in orchards give the Haut-Richelieu a unique profile. Here’s what a local exterminator watches closely.

    Richelieu and Lake Champlain
    2 banks
    The Richelieu runs through Saint-Jean on two banks and leads to Lake Champlain and Missisquoi Bay

    Water everywhere, critters with it

    Banks, marshes and docks favour carpenter ants, mosquitoes, waterside rodents and damp-loving insects. We inspect the surroundings, seal the entries and keep the water on your side rather than the pests’.

    Source: hydrographic profile of the Haut-Richelieu
    Intensive agriculture
    14
    The region has 14 municipalities, several devoted to large crops and livestock

    The fields spill toward the homes

    Cereals, dairy and pig farms and grain silos feed voles, field voles and silo rats year-round. On the farm as at home, we combine sealing, secured stations and upkeep to keep the populations under control.

    South
    Southern Montérégie, up to Mont Saint-Grégoire, is among the areas most affected by Lyme disease

    Lyme, well settled here

    The mountain trails, the orchards and the tall grass give ticks the habitat they seek, and they get active as soon as it hits 4 degrees. We show you how to clear the surroundings and protect yourself after a walk.
