Minimum 6-Month Service Warranty

All mouse exterminations and treatment services include a 6-month service warranty.

Warranty coverage depends structure, and findings at inspection. Full terms are reviewed prior to treatment or service. 

MICE CONTROL SERVICES IN TORONTO

Mouse activity in Toronto homes is typically the result of structural entry points, interior movement pathways, and environmental pressure rather than surface conditions alone.
Our mouse control services are based on observed building conditions and documented patterns from completed service calls across Toronto.

LICENSED. INSURED. TORONTO BASED.

  • Licensed by the Ontario Ministry of the Environment

  • Fully insured for residential and commercial work

  • Local technicians trained in inspection-based pest control

  • Structured documentation and service records for every job

  • Service warranties explained prior to work taking place

What sets us apart
  • Assessment
    Mouse activity is assessed by identifying entry points, movement pathways, and nesting areas rather than reacting to where mice are seen. Interior sightings often reflect concealed movement elsewhere in the structure.

  • Approach
    Effective mouse control depends on understanding how a building allows access and movement. We focus on construction details, entry points, and voids that enable repeated activity, not just visible symptoms.

  • Treatment / Control
    Control measures are implemented during the service visit based on conditions observed on site. We typically use bait stations with commercial grade rodenticide.

  • Follow-Up (If Required)
    Follow up visits can be required to fully suppress a mouse problem. In most cases sealing mouse entry points is required to fully mouse proof a structure. 

How We Treat Mouse Control Service Calls

You call

Speak with experienced staff who assess the situation and, where appropriate, arrange a rodent control service call based on urgency and availability.

Inspection

Once on site, the technician evaluates entry points, interior movement pathways, and areas that allow mice to enter or remain concealed within the building. 

Treatment

Treatment is carried out during the same visit based on what is observed on site. Mouse control typically begins with an interior treatment. An exterior treatment might also be required. 

Recommendations 

Based on the findings, the technician documents observations and provides clear recommendations for sealing, exclusion, or follow-up service if required.

Mouse Patterns We See in Toronto Homes

Mice - What We See Repeatedly

Across documented mouse cases throughout Toronto, consistent patterns emerge. Mouse problems are rarely caused by a single visible opening or an obvious structural problem. Instead, mice exploit extremely small gaps in the building envelope—often in areas that are difficult or impossible for homeowners to see. Once established inside a home, they stay and establish a population. 

 

Toronto Mouse Problems are Patterned

By the time mice are observed in kitchens, cabinets, or attics, they have typically already accessed the structure and established concealed movement routes through walls, floors, decks, plumbing voids, and rooflines. Older homes, multi-storey houses, and properties with decks or complex exterior details show increased vulnerability, making exclusion and proofing critical for long-term control.

What Our Mouse Case Studies Reveal

1. Small gaps are sufficient for access

Mice are able to enter through extremely small entry points around the house, many of which appear sealed or insignificant at a glance.

  • Utility line Openings
  • Soffit-brick gaps
  • Weep Vents
  • Small gaps around doors

What this means:
Just like with rats, mouse problems are rarely caused by one obvious hole, and effective control depends on identifying and addressing several small access points across the structure.

2. Interior sightings usually indicate established activity

When mice are seen inside living spaces, they have typically already accessed the structure and established internal movement routes. These pathways allow them to travel between walls, floors, and ceilings before appearing in visible areas. Mouse droppings are similar in size to a grain of rice. Aside from seeing live mice, finding mouse droppings is the #1 indicator of mouse activity. 

What this means:
An indoor sighting usually reflects an establish population due to an ongoing structural issue rather than an early or isolated event.

3. Exterior features frequently enable access

The same features recur across cases:

  • Decks (especially raised or aging)
  • Crawlspaces and cold cellars
  • Below-grade foundation walls
  • Wall cavities
  • Soffit and roofline intersections

These areas provide shelter, warmth, concealment, and travel routes.

What this means: Exterior building features play a significant role in mouse activity and must be evaluated as part of any lasting solution.

4. Kitchens and Attics are destinations

Areas such as kitchens, cabinets, and attics are where mice are most often noticed, but these locations are rarely where entry occurs. Mice use concealed routes to reach these spaces in search of food, water and nesting areas after entering elsewhere in the building.

What this means:

Treating only the room where mice are seen, or only the attic often fails because the true access points are located outside those spaces.

5. Vertical access is common

Mice are capable climbers and routinely access upper levels of a structure by moving vertically along walls, brickwork, or other surfaces. Attic activity often occurs without any ground-level entry.

What this means: Mouse entry cannot be assumed to occur at ground level, and upper portions of the structure require equal attention.

6. Exterior features often reinforce interior activity

Decks, foundations, open weep vents, and soffit openings provide mice with protected routes into a structure. These features can conceal gaps, allow climbing, or connect exterior conditions directly to interior voids.

What this means: Exterior building features play a significant role in mouse activity and must be evaluated as part of any lasting solution.

7. Treatment alone rarely holds without exclusion

Removing mice without addressing how they are entering the structure often results in repeat activity. Control measures may provide short-term relief, but unresolved access points allow re-entry.


What this means: 

Long-term resolution depends on pairing control with structural exclusion and proofing.

8. Mouse activity often overlaps with other pressure

Mouse problems frequently coexist with other pest or wildlife pressure that exploits the same structural weaknesses. These overlapping pressures can complicate control if not recognized.

What this means: Addressing the underlying structural vulnerabilities is often necessary to dealing with ongoing or recurring mouse problems.

9. Older and multi-storey homes often require staged work

Homes with multiple levels, additions of older construction tend to have more entry points and established access and travel trails. In these cases, verification and follow-up work are sometimes required after initial control.

What this means: 

Some mouse problems cannot be resolved in a single step and require a staged approach. Treatment, follow ups and exclusion.

Every Structure is Different. Mouse Activity Follows Patterns

No two buildings are identical. Differences in age, construction methods, renovations, exterior features, and maintenance all influence how mice are able to access and move through a structure.

While each home presents unique conditions, mouse activity consistently follows recognizable patterns. Mice exploit small gaps, concealed voids, and protected pathways that allow them to enter undetected and move internally before appearing in visible spaces. These patterns repeat across different neighbourhoods and building types, even when the specific access points differ.

This is why mouse problems often appear unpredictable. The visible activity is only the final stage of a process that began elsewhere in the structure. Lasting control depends on understanding how the building is being used by mice and addressing those pathways, rather than focusing only on where mice are seen.

If you’re dealing with a mouse issue and want to understand what’s happening at your property, you can speak with experienced staff to discuss the situation and determine whether a service call is appropriate.
