Mouse & Rat Control in St. Catharines

Mice & Rats in St. Catharines: what to know

St. Catharines is Niagara's largest city, with everything from older brick homes near downtown and Port Dalhousie to newer subdivisions in the west end, plus plenty of apartments and student rentals near Brock University.

• Properties near the lake and creeks can see more rodent pressure, especially where there is brush, docks or boat storage.
• Areas near the canal and its industrial land can have more rats and mice, which look for shelter in nearby homes as the weather cools.
• Shared rentals with lots of food storage and frequent move-ins and move-outs can attract mice, especially in fall.
• Older foundations, stone basements and gaps around old pipes are common ways for mice to get in.

Calls usually go up in fall, when rodents move indoors for warmth.

Signs of mice & rats in your home

• Droppings in cupboards, drawers, along baseboards or behind appliances
• Gnaw marks on food packaging, wires or wood
• Scratching or scurrying sounds in walls or ceilings, often at night
• Greasy rub marks along walls and nests made of shredded paper or insulation

What mouse & rat control usually involves

A provider will look for how rodents are getting in and where they are active, then set up a trapping or baiting program placed safely away from children and pets. The longer-term fix is exclusion: sealing entry points so new rodents can't get in. Follow-up visits check activity and remove traps.

Prevention tips for St. Catharines homes

• Seal gaps around pipes, vents, and where utilities enter the house; mice fit through very small openings
• Store food, pet food and birdseed in sealed containers
• Keep firewood, compost and debris away from the foundation
• Trim shrubs and vines that touch the house

When to call

Call when you see droppings or hear activity in walls or ceilings. Rodents breed quickly and can damage wiring and insulation.
