FOUNDATION GAPS AND CRACKS
Foundation gaps and cracks at ground level, especially on older homes.
Free inspection. Burrows sealed, not just baited.
Rat removal Toronto problems rarely start indoors. Most start outside, in a burrow near a foundation, deck, or shed. GTA Pest Solutions is a licensed & insured exterminator.
A rat control Toronto job that only sets indoor traps misses the colony outside. We treat both.
Every visit follows Integrated Pest Management (IPM): inspect, exclude, treat, then monitor. Rats are more cautious than mice, so this takes patience, not just bait.
Seeing burrow holes or hearing scratching at night? Same-day appointments available.
House mice, Norway rats, and roof rats differ in size, droppings, nesting locations, and behaviour. Identifying the likely species can help determine where to inspect and which control approach may be appropriate.
| Comparison | Norway Rat | Roof Rat |
|---|---|---|
| Scientific Name | Rattus norvegicus (Norway rat) | Rattus rattus (roof rat) |
| Body | Heavy, 7–9.5 inches, with a blunt nose. | Slender, 6–8 inches, with a pointed nose. |
| Where Found | Ground level: burrows, basements, and sewers. | Climbs into attics, rooflines, and trees. |
| Entry Behaviour | Digs burrows near foundations and sheds. | Enters via rooflines, utility lines, and vines. |
Most GTA rat activity is Norway rat control, since roof rats are less common this far north. Still, older homes near mature trees sometimes see roof rat removal cases in the attic instead of the basement.
Not sure which rat you have? A photo of droppings or a burrow usually confirms it.
If you notice repeated signs or cannot locate the entry point, a professional inspection can help identify the source of the activity.
Rats leave more visible evidence outdoors than mice do. Watch for:
If you notice repeated signs or cannot locate the entry point, a professional inspection can help identify the source of the activity.
Rats are bigger, but the real difference is behaviour. Rats are neophobic — naturally suspicious of new objects. A trap set on day one often sits untouched for a week while rats size it up.
Rats also burrow outdoors, which mice rarely do in the GTA. This means rat infestation treatment usually needs outdoor burrow treatment as well as indoor work — a step most DIY attempts skip entirely.
Rats contaminate food and surfaces with droppings and urine. The main risks are Leptospirosis and Salmonella. Rat-bite fever is rare but possible from direct contact.
Property damage is often worse than with mice. Burrows can undermine foundations, decks, and garden beds. Gnawed wiring is a real fire risk.
One honest warning: DIY rat poison often backfires. Poisoned rats frequently die inside wall voids, where the smell can take weeks to clear and may require opening a wall to remove the carcass. This is one of the main reasons we favour trapping and exclusion over open bait wherever possible.
This isn’t a scare tactic. It’s documented. City of Toronto 311 rat complaints reported to CBC News climbed from roughly 940 in 2019 to nearly 1,600 by 2023.
Construction and aging sewer infrastructure are the main drivers. The City has since launched its first formal Rat Response Plan.
The plan analyzes 311 data and bylaw inspections to target infestation hotspots. It’s also testing non-rodenticide controls like carbon monoxide burrow treatment.
For GTA properties, the takeaway is simple. Nearby construction, aging sewer lines, and ravine corridors all raise your odds of rat pressure, regardless of how clean a property is kept.
Activity also shifts by season: burrows expand in spring as young rats disperse, and rats push indoors in late fall as temperatures drop. Any rat removal GTA or rat control GTA plan should account for both.
One more honest note for row houses and semi-detached homes: rats travel between shared walls and adjoining yards. Treating your side alone rarely holds if a neighbouring property has an untreated burrow.
Rats need a gap about the size of a quarter — smaller than most people expect. Common entry points:
Foundation gaps and cracks at ground level, especially on older homes.
sewer rat control Toronto cases sometimes involve rats entering through cracked pipes or even toilets.
Utility penetrations where pipes or wires pass through walls.
Garage and shed gaps, particularly at the base of doors.
Roofline and soffits for roof rats climbing from nearby trees.
Not sure where they’re getting in? A free inspection will find it.
Yes. Under Section 20 of the Residential Tenancies Act, 2006, landlords must keep rental units fit for habitation and free of rodents. Ontario Regulation 517/06 sets this out explicitly as a maintenance standard.
This duty can’t be shifted to tenants through a lease clause. Landlords must act on a rat complaint promptly, whether or not they caused it.
For property managers, this makes documented, professional rat control near me service more than a courtesy. It’s a compliance requirement that protects against Landlord and Tenant Board disputes.

Every job follows the same Integrated Pest Management (IPM) sequence used by licensed operators across Ontario:
We check indoors and outdoors for burrows, runways, droppings, and every entry point.
Gaps get sealed with steel mesh, concrete patching, and heavy-gauge hardware cloth. A rat only needs a gap the size of a quarter.
Active burrows are treated and collapsed so they can’t be reused.
Tamper-resistant bait stations and snap traps are placed along confirmed runways, away from children and pets.
Stations and traps get checked on a schedule until activity fully stops, since rats take longer to trap than mice.
Ready to start? Get a firm price after a free inspection.
Rats are more cautious than mice, so results take longer. Most properties see a drop in activity within 2 to 3 weeks.
Full elimination of an established colony, including sealed burrows and a quiet perimeter, can take up to 8 weeks. An honest timeline serves you better than a promise we can’t keep.

Homeowners searching get rid of rats Toronto usually want a fast answer. Here’s the honest one:
Rats are bait-shy and cautious. A few store-bought traps rarely clear an established colony.
You find burrows, hear activity in walls or under decks, or see rats during the day. Daytime sightings often signal a large colony.
A rat that dies in a wall void is far harder to deal with than one caught in a trap.
Not sure how bad it is? Send a photo and we’ll tell you honestly.
We use tamper-resistant bait stations placed only where children and pets can’t reach them, and favour mechanical trapping over open rodenticide wherever the infestation allows.
For active burrows near a property line, controlled exclusion techniques can encourage rats to leave without trapping them inside a collapsing burrow. This is what we mean by humane rodent control: removing the problem without unnecessary harm.

Droppings, gnaw marks, nesting material, scratching sounds, and the location of activity can help identify the problem. Mouse droppings are generally smaller and more pointed, while rat droppings are larger and more blunt. If you're unsure, a professional inspection can help identify the likely species.
The cost depends on the species, level of activity, number of entry points, property size, and whether exclusion or follow-up work is required. An inspection allows the scope of treatment to be assessed before providing a quote.
When rodenticides are used, they should be placed in appropriate tamper-resistant bait stations and used according to the product label and applicable requirements. Trapping may also be appropriate depending on the situation.
Simple cases may show a reduction in activity relatively quickly, while established infestations with multiple entry points can require additional treatment and monitoring. The expected timeline depends on the inspection findings.
Yes. GTA Pest Solutions provides rodent-control programs for restaurants, warehouses, offices, property managers, and other commercial properties, with treatment and monitoring plans based on the site's needs.
No. Many GTA rodent populations have grown resistant to older baits like warfarin, so we don’t rely on bait alone anyway. We offer a trap-first, non-toxic option built around exclusion and mechanical trapping.
Sealing accessible entry points is an important part of preventing reinfestation, but it should be combined with appropriate treatment and monitoring when rodents are already inside. Health Canada also identifies rodent-proofing and sealing openings as key prevention measures.
Yes. The service covers common indoor rodent problems including house mice and rats, with the treatment approach adjusted according to the species and property.
We are a trusted pest control service provider offering safe, effective, and solutions homes and businesses.
