Mercier has 14,626 residents as of the 2021 census and is part of Roussillon RCM. Incorporated as a municipality in 1855 and a town since 1964, it covers nearly 46 km². The rivière Châteauguay borders it to the west and the rivière de l’Esturgeon crosses its southwest. Route 138, boulevard Saint-Jean-Baptiste, meets rue de l’Église in the heart of town, and its neighbours to the south and west are Sainte-Martine, Saint-Isidore and Saint-Urbain-Premier.
Two rivers and a rural neighbourhood
Mercier is a suburban town set between two rivers and more rural municipalities. That mix of water, trees and open land explains the two pests that dominate: mice and carpenter ants.
The most common pests in Mercier
Mice. In the fall, mice from open land and riverbanks move toward houses. They get in through a gap of a few millimetres: see how to seal mouse entry points.
Carpenter ants. On riverside lots along the Châteauguay River, damp wood in decks, fences and stumps attracts colonies. The main carpenter ant nest is often outside: see how to find it.
Wasps. Soffits, sheds and hedges host wasp nests from June to September.
Skunks and raccoons. Lots near woods and rivers see them pass. A useful reminder: in Mercier, moving a live raccoon or skunk is prohibited because of rabies.
Businesses on route 138
Along boulevard Saint-Jean-Baptiste, food businesses have specific pest obligations. See the page on commercial pest management for the records to keep.
The local calendar
- April to June: carpenter ants near the rivers.
- June to September: wasps.
- September to November: mice.
The work and the timing
In Mercier the usual sequence is: inspect the perimeter and utility entries, seal with metal, then set traps and follow up. On a riverside lot, add an inspection of outdoor wood and stumps. For a business on boulevard Saint-Jean-Baptiste, the program has to be documented. No timeline is guaranteed on this site.

Frequently asked questions
Why mice in Mercier every fall?
Mercier is bordered by the Châteauguay River, crossed by the rivière de l'Esturgeon and surrounded by more rural municipalities such as Sainte-Martine and Saint-Isidore. In the fall, mice from that open land look for shelter and get in through foundations.
Do lots along the Châteauguay River have more carpenter ants?
Riverside moisture and mature trees favour carpenter ants in outdoor wood: decks, fences, stacked wood. The main nest is often outside, a few metres from the house.
Who handles a wasp nest along boulevard Saint-Jean-Baptiste?
A nest on public land is the Ville de Mercier's responsibility. On your lot or commercial building, the owner has it treated.
Do businesses on route 138 have specific obligations?
A business selling food must keep its premises free of pests under MAPAQ's Regulation respecting food. See the commercial pest management page for the records to keep.
When should I act against mice?
Before they get in: sealing foundations and utility entries is ideally done in August or early September.
Is a house far from the rivers safe?
Less exposed to carpenter ants, but not to mice: open land and the rural municipalities nearby, such as Saint-Isidore and Sainte-Martine, supply the same rodents in the fall, whatever the street.
How many visits does a mouse problem take?
Usually one inspection-and-sealing visit, then one or two follow-ups depending on activity. A quote that only sets traps, without sealing, lets the problem come back the following fall.
