The Haut-Richelieu is a mosaic of 14 municipalities: two banks of the Richelieu, intensive farmland and the surroundings of Lake Champlain, each with its critters. Find yours. We know the ground.

2 sectorsIn 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.
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 ticksSummer
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 waspsFall
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 rodentsWinter
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 wallsThree 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.
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’.
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.
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.
Our findings in Saint-Jean, sector by sector
In Saint-Jean-sur-Richelieu, what we really notice when working at your place. The type of building and the closeness to the water often say more than any regional average.
Old Saint-Jean
The heritage heart of the two banks. Carpenter ants in the old wood and rodents near the Richelieu, the moment you let your guard down.
Saint-Luc and L’Acadie
New neighbourhoods near the fields. Field mice come in in the fall and carpenter ants target the new terraces.
Farming rangs
Farms, silos and large crops. Voles, field voles and silo rats take advantage of the stores year-round.
Around Lake Champlain
Lacolle, Noyan and Venise-en-Québec. Mosquitoes and bed bugs follow the vacationing and the border.
Mont-Saint-Grégoire
Mountain, orchards and maple groves. Ticks on the trails and wasps drawn by the apples in late summer.
The right treatment in Saint-Jean, pest by pest
In Saint-Jean-sur-Richelieu, each pest has its proven method. The button leads to the detailed, priced service; the small link to the fact sheet to identify what you spotted.
Carpenter ants
The number-one pest of the two banks of the Richelieu, fond of the damp old wood. We follow the trail to the mother nest, lodged in a water-soaked beam, and eliminate it at the source with a bait the workers carry back to the nest. Not just a spray.
Mice, voles and field voles
The great classic of the farms and new neighbourhoods near the fields of the Haut-Richelieu. We spot the entries, seal them and install secured stations to break the cycle, in the barn as in the house.
Cockroaches
Mostly in the plexes and shops of central Saint-Jean. Targeted gel that passes from one insect to the next up to the nest, without emptying your cupboards or disturbing the neighbours.
Rats
Present along the Richelieu, in the silos and old sectors. We inspect banks, drains and foundations, block access and control the population before it reaches the farms and homes.
Bed bugs
In Saint-Jean, frequent in the region’s homes and lodgings, all the way to the shores of Lake Champlain. Heat or targeted treatment as the case requires, with a clear plan against their return. We stay discreet; no one needs to know.
Wasps and hornets
The number-one emergency of summer, from the downtown terraces to the orchards of Mont Saint-Grégoire. We find the nest, even hidden in a wall or under a cornice, and neutralize it in one visit, safely for the family.
