Granby has 69,025 residents as of the 2021 census and, in La Haute-Yamaska RCM, forms the farthest zone of the territory. The rivière Yamaska Nord crosses it at its centre and feeds lac Boivin; the Zoo de Granby and parc Daniel-Johnson are its best-known landmarks. Autoroute 10 is the main access road, and boulevard David-Bouchard, route 139, is its main commercial strip.
A town between water, woods and major roads
Downtown, around rue Principale and rue Denison, holds the oldest buildings. Around it, residential neighbourhoods touch natural areas such as the Boisés Miner and the shores of Lac Boivin. That closeness of water and woods, right in the middle of town, explains much of its pest profile.
The most common pests in Granby
Mice. In the fall, mice leave the woods and open land for the nearest foundations. Older downtown houses and homes next to natural areas are the most exposed.
Carpenter ants. Damp exterior wood near the Yamaska Nord River, Lac Boivin or the woods draws carpenter ants. The main nest is often outdoors, in a stump or a dead tree.
Asian lady beetles. Light-coloured, sunny walls, especially next to open space, get clusters of Asian lady beetles every fall.
Wasps. Soffits, decks and sheds host wasp nests from June to September.
The local calendar
- April to June: carpenter ants, often winged indoors in spring.
- June to September: wasps; mosquitoes near Lac Boivin and the river.
- Late September to November: mice and Asian lady beetles.
- Winter: mice already inside, active in basements.
The work and the timing
Granby sits on the line between farmland and woods, so a useful inspection covers both: the foundation perimeter and the strip of ground that touches the woodlot or the field. Sealing first, traps second, then a follow-up visit. No timeline is guaranteed here; insist on a date and a number of visits in writing.
Requesting service in Granby
Granby makes up the Haute-Yamaska zone. The quote request for Granby opens with the town already selected. No response time is guaranteed, and availability is more limited than in the heart of the South Shore.
Mention in the description whether your home borders woods or water. Insist on a written quote that includes any travel fee, and ask to see the technician’s CD5 certificate. Price ranges are on the treatment costs page.

Frequently asked questions
Is Granby really served, so far from the South Shore?
Granby is part of Montérégie, like every town in the territory, and forms its own zone. Because it is farther away, availability there is more limited and never guaranteed in advance: this is made clear when you send a request.
Do homes near Lac Boivin have more pests?
Moisture near the water and the natural areas around the lake mostly favour carpenter ants in exterior wood, and mosquitoes in summer. Mice get in everywhere in the fall, near water or not.
Why carpenter ants in a downtown house?
Older downtown houses, around rue Principale and rue Denison, have wood framing and decks that have had time to take on moisture. A clogged gutter or a leak is enough to create the softened wood a colony looks for.
When should I seal up in Granby?
Before the end of September. That is when mice move toward foundations and Asian lady beetles start gathering on sunny walls.
Do the downtown working-class houses have particular pests?
Their age mostly affects entry points: cracked foundations, sills and utility entries let mice in during the fall. Older outdoor wood, for its part, interests carpenter ants when it stays damp.
Are the developments near lac Boivin and the Boisés Miner more exposed?
A house built against a woodlot has dead wood and moisture a few metres away: the classic carpenter-ant pressure, with mice in the fall. Wooded areas are also habitat for the blacklegged tick.
