Mouse exterminator in Brossard
Brossard has two sources of mice that have nothing to do with each other. Around the REM stations, Quartier DIX30 and boulevard Lapinière, major construction disturbs the soil and removes the vacant land where rodents lived. In the older lettered sectors (secteurs à lettres), foundations and decks several decades old let mice in every fall.
First source: construction
Brossard is changing fast around its three REM stations, station Panama, station Du Quartier and station Brossard, and around Quartier DIX30. Those projects have a side effect that rarely gets mentioned: vacant land that disappears under an excavation is also rodent habitat that disappears. The mice that lived there move toward whatever shelter remains nearby, including neighbouring houses and buildings.
This mechanism is not unique to Brossard, and no public figure measures it here. It does explain mice turning up out of season, in spring or summer, in neighbourhoods close to construction.
Second source: the lettered sectors
In the older sectors, the problem is more classic and follows the usual calendar: mice arrive in the fall. The houses are several decades old, and three things come up often:
- foundations and utility entries, cracked by years of freeze and thaw;
- wooden decks and patios, under which mice shelter against the house;
- row houses, where shared walls let mice move from one home to the next.
Treatment depends on the source
The general protocol is on the mice page. In Brossard it adapts to the source:
- Near construction or in a new building, for example along autoroute 10 or boulevard Taschereau: inspecting underground garages, service rooms and pipe chases; coordinating with building management; extended monitoring while nearby work continues.
- In a house in the lettered sectors: a full foundation inspection, metal sealing of entry points, a garage door sweep, clearing the space under the deck.
- In a row house: sealing coordinated with neighbours where possible, otherwise extra attention to shared walls and attics.
In every case, snap traps come after exclusion, not before.

Frequently asked questions
Construction started near my place and now I have mice. Is there a link?
Possibly. Major works that turn over the soil and remove vacant land can push rodents into nearby homes. It is a known mechanism, not a figure measured for Brossard. Either way, the fix is the same: find and seal the foundation entry points.
I live in a new condo near the REM. How can mice get in?
Through underground garages, service rooms and pipe chases between floors, especially in the first years while construction continues around the building. Tell management: the building needs inspecting, not just your unit.
Do row houses share mice?
Yes. In a row, mice can pass from one house to the next through shared walls and common attics. A problem next door deserves an inspection at your place, and sealing done on one side only holds poorly.
Which part of Brossard is worst?
No public data ranks the sectors. Risk depends mostly on the age of the house, the condition of its foundation and how close it is to open land or construction, more than on the sector's letter.
