Rodent Control
Professional Rat &
Mouse Extermination
in Ontario

The two most common rodents found in Ontario homes and businesses are the Norway rat (also called the brown rat or sewer rat) and the house mouse. Norway rats are large, burrowing rodents that tend to live at or near ground level — in basements, crawl spaces, and wall voids near foundations. House mice are smaller, highly adaptable, and can be found everywhere from the basement to the attic. Roof rats, while less common in Ontario, are occasionally found in older structures near ports and waterways.

Key signs of a rodent infestation include: droppings near food sources, along walls, or in cupboards (Norway rat droppings are capsule-shaped at 25–30 mm; mouse droppings are tiny spindle shapes at ~6 mm); gnaw marks on food packaging, wiring, wood, or plastic; scratching sounds in walls or ceilings at night; nesting material (shredded paper, insulation, fabric) in hidden areas; grease marks along baseboards from fur rubbing on surfaces; and a musty, ammonia-like odour in enclosed spaces.

Yes — rodents are among the most disease-carrying pests. They transmit over 35 diseases to humans including Hantavirus (spread through airborne droppings particles), Salmonellosis (food poisoning), Leptospirosis (bacterial infection from urine-contaminated water), and Rat-Bite Fever. Their droppings and urine contaminate food and surfaces, and even dried droppings stir up dangerous airborne pathogens when disturbed. People with allergies or asthma may also react to rodent dander.

Yes. Rodents chew constantly to wear down their ever-growing incisors, and electrical wiring is a common target. When they strip the insulation from wires inside walls, attics, or crawl spaces, exposed wires can arc and ignite nearby insulation or wood. Fire investigators estimate that rodent damage to wiring is responsible for a significant percentage of house fires with undetermined causes. If you have a rodent infestation, having your electrical system inspected after treatment is strongly recommended.

Over-the-counter snap traps and poison baits address individual rodents but do nothing to eliminate the population or seal the entry points that allowed them in. Rodents breed faster than traps can catch them — removing a few mice while dozens more are being born nearby provides no lasting control. Additionally, improper placement of rodenticide baits poses risks to children, pets, and non-target wildlife. Professional treatment addresses the infestation at its source with strategically placed tamper-resistant stations and proper exclusion work.

Mice can squeeze through any gap 6 mm or larger — about the width of a pencil. Norway rats need only 12 mm. Common entry points include gaps around utility pipes and conduits entering the foundation, cracks in the foundation or basement walls, unsealed weep holes in brick, damaged soffit vents or roof vents, gaps under garage doors, and openings around poorly sealed doors and windows. Rodents also enter through attached garages and shared walls in townhomes and apartments.

The initial inspection and treatment setup typically takes 1–2 hours depending on property size. Bait stations and traps are monitored and serviced over a period of 1–3 follow-up visits over the following weeks to ensure the population is fully eliminated. Exclusion work (sealing entry points) is performed as part of the treatment. The total process from initial visit to confirmed resolution typically takes 2–4 weeks for a standard residential infestation.
