Sainte-Catherine has 17,347 residents as of the 2021 census and is part of Roussillon RCM. Incorporated as a municipality in 1937 and a town since 1973, it covers 16 km² on the south shore of the fleuve Saint-Laurent, facing the rapides de Lachine. The Voie maritime du Saint-Laurent runs through it at the écluse Côte-Sainte-Catherine, the rivière Saint-Régis and rivière Saint-Pierre cross it, and the Récré-O-Parc, on île du Seigneur, is a migratory bird refuge. Route 132 carries its commercial strip, and the pont Honoré-Mercier is close by.
A town turned toward the water
Between the river, the Seaway and two smaller rivers, much of Sainte-Catherine lives close to water. That moisture, more than the age of the houses, explains most of the pests found here.
The most common pests in Sainte-Catherine
Mice. In the fall, mice from riverbanks and nearby land look for dry shelter. They get in through foundations and utility entries: the page on mice in the house covers the sealing to do.
Carpenter ants. Outdoor wood that stays damp near the water (decks, sills, fences) attracts colonies. See how to recognize carpenter ants in damp wood.
Wasps. Soffits, hedges and big green spaces host wasp nests in summer.
Rats. Rare on residential streets, they follow food sources: dumpsters in the route 132 commercial strip, open compost, feeders. The page on Norway rats explains how to spot them.
Mosquitoes. Near the river, standing water in yards makes the difference: see the page on mosquitoes.

The work and the timing
In Sainte-Catherine, the perimeter and the outdoor wood exposed to river moisture are inspected first, then sealed before any traps go in. For wasps, the work is done at the nest, preferably early morning or evening. No timeline is guaranteed here: have the method, the number of visits and the follow-up spelled out in the quote.
Requesting a quote in Sainte-Catherine
Sainte-Catherine is part of the Roussillon zone. The Sainte-Catherine quote request opens with the town already selected. Mention whether your lot borders the water or a woodlot.
Insist on a written quote that spells out the method and planned visits, and ask for the technician’s CD5 certificate. Published ranges are on the page about treatment costs. The neighbouring towns of Delson, Saint-Constant and Candiac have their own profiles.

Frequently asked questions
Does living near the river bring more pests?
Moisture from the fleuve Saint-Laurent and the Saint-Régis and Saint-Pierre rivers mostly favours carpenter ants in outdoor wood, mosquitoes in summer and mice looking for dry shelter in the fall.
Is it normal to see rats in a residential area?
It is not common, but open compost, seed spilled from a feeder or accessible garbage is enough to feed rats. The commercial strip on route 132, with its dumpsters, is a possible source for nearby streets.
Does the Récré-O-Parc bring wasps near homes?
Large green spaces host ground-nesting wasps and bumblebees. They mostly stay in the park; a nest near your own door or play area is what calls for treatment.
Who handles a wasp nest on a bike path or in a park?
A nest on municipal land is the responsibility of the Ville de Sainte-Catherine: report it to its citizen services. On your own lot, you have it treated.
When should a house near the water be inspected?
In spring for carpenter ants, when damp wood is most active, and in late summer to seal entry points before mice arrive.
Can waterfront mosquitoes be treated?
A yard treatment cuts adults for a few weeks, but the real difference comes from standing water on the property: saucers, tarps, gutters, birdbaths. Empty them once a week.
Do the Récré-O-Parc and the riverbanks bring rodents toward houses?
Banks and green spaces act as corridors for rodents, especially in the fall. What makes the difference at your place is still access: utility entries, garage door bottoms and reachable compost.
