Mice & Rat Extermination Services

Q: What size hole can a mouse fit through?

A mouse can squeeze its entire body through a gap the size of a dime, or roughly a quarter of an inch (6mm). Rats can fit through a hole the size of a quarter (19mm).

Q: Will the poison cause mice to die and smell in my walls?

Commercial rodenticides cause profound dehydration, prompting the mouse to usually seek water outdoors before dying. If one dies inside, the dehydration process minimizes odor.

Q: Are ultrasound plug-in repellers effective against mice?

No. Mice quickly become habituated to the high-frequency sound after 48 hours. Physical steel exclusion is the only permanent solution for long-term rodent eviction.

You hear the scratching in the ceiling at 2:00 AM. You find droppings under the kitchen sink. As the Canadian winter approaches, mice and rats aggressively seek shelter, and your heated home is their prime target. Pestisect offers comprehensive rodent control and, more importantly, rodent exclusion. We guarantee not only to remove the active mice from your property but to seal the structure so they cannot return next year.

Why Rodent remove

The Threat: Why Rodents Must Be Removed Immediately

Mice and rats are not just unsanitary; they are destructive structurally and present massive safety hazards.

Fire Hazards

A rodent’s front teeth never stop growing. To file them down, they continuously gnaw on hard objects, specifically electrical wiring in your walls or attic. Exposed, chewed wiring is a leading cause of unexplained house fires.

Disease Vectors

Mice leave a constant trail of urine as they walk. They carry Hantavirus, Salmonellosis, and Leptospirosis, spreading these directly across your kitchen counters and pantry shelves.

Rapid Breeding

Two mice inside a wall void can multiply into a colony of two dozen within a few months. If you hear one mouse, there are always more.

What is Rodent Exclusion? Rodent exclusion is a permanent pest control technique where technicians use materials like galvanized steel mesh, concrete, and heavy-duty sealants to physically block structural gaps and holes on the exterior of a building, permanently preventing rodents from re-entering.

Industry Fast Facts:

A female house mouse can have up to 10 litters per year, with 5-6 young per litter.
Rats can exert a biting pressure of up to 7,000 pounds per square inch (psi), allowing them to chew through wood, plastic, aluminum, and even soft concrete.
A mouse can squeeze its body through a hole the size of a dime (6mm), while a rat can fit through a hole the size of a quarter (19mm).

Mice & rat remove Process

Pestisect's Permanent Exclusion Strategy

Putting down a few wooden snap traps from the hardware store does not solve a mouse problem. It treats the symptom, not the source. If the hole in your exterior brickwork remains open, new mice will simply migrate in to replace the ones you caught.

Step 1: The Exterior Inspection

Our technicians conduct a massive audit of your home's exterior — foundation, utility line entries, weeping holes, garage seals, and rooflines. We locate exactly how the rodents are bypassing your walls.

Step 2: Interior Trapping & Baiting

We utilize professional, locked, tamper-proof rodenticide bait stations and highly sensitive snap traps in strategic, high-activity areas (basements, drop ceilings, under sinks). These quickly reduce the active indoor population while keeping children and pets completely safe.

Step 3: Steel Exclusion Sealing (The Permanent Fix)

Catching the interior mice is useless without this step. We seal every entry point found during our inspection using heavy 16-gauge galvanized steel mesh, construction-grade caulking, and specialized expanding foams. Mice cannot chew through our steel mesh, permanently securing your property boundaries.

Identify

Identifying the Culprit: Mouse or Rat?

In the Greater Toronto Area, we primarily deal with the House Mouse and the Norway Rat. Treatment strategies differ significantly based on the species.

The House Mouse

Small (2–4 inches). Their droppings look like tiny, pointed black seeds. They are highly curious, making them easier to trap. They easily nest inside the voids of interior walls.

The Norway Rat (Brown Rat)

Large and stocky. Their droppings are much larger, cylindrical, and blunt-ended. They are "neophobic" (extremely afraid of new objects), making trapping highly complex. In Toronto, they frequently live in underground sewer systems and burrow under exterior concrete slabs or decks.

Frequently Asked Questions About Rodents

What size hole can a mouse fit through?

A mouse’s skeletal structure requires very little space. If their skull fits, the rest of their body can squeeze through. A mouse can easily fit through a gap roughly the size of a dime (6-7 millimeters). A rat can fit through a hole the size of a quarter.

Will the poison cause mice to die and smell in my walls?

This is a frequent concern, but it is heavily mitigated by modern professional baiting. Commercial rodenticides cause profound dehydration. The mouse naturally seeks water, meaning it usually leaves the warm house for the outdoors before dying. If one does die inside, the dehydration process rapidly dries out the carcass, significantly minimizing odor compared to traditional traps.

Are ultrasound plug-in repellers effective against mice?

No. While ultrasonic repellers may cause initial irritation to a mouse for the first 48 hours, they quickly become habituated to the noise. They are not a viable solution for long-term control. Physical exclusion is the only permanent solution.

How did a mouse climb into my attic?

Mice are exceptional climbers. They can easily climb up the textured exterior brick of your home, up downspouts, or across overhanging tree branches to enter your roof line through vulnerable soffits or roof vents.
