Job Overview
Location: Toronto, Ontario
Structure: Two-story Victorian century home
Problem: Interior mouse activity reported throughout the home
Service: Mice treatment
Visits: 1
Summary
Our team responded to reports of mouse activity inside a two-story Victorian century home in Toronto during February. Richard attended the property, confirmed active mouse presence, and initiated a rodent control program. Due to winter conditions, snow coverage assisted with tracking exterior wildlife activity and identifying structural vulnerabilities contributing to rodent entry.
Tamper-resistant bait stations containing commercial-grade rodenticide were strategically placed inside the home to address the active population. All work was performed by a licensed exterminator in accordance with Ontario Ministry of the Environment guidelines.
Background / Property Context
The property is a century-old Victorian home with original architectural features. Homes of this age often contain aging materials, settled foundations, and gaps around windows, doors, and exterior framing.
Winter snow accumulation surrounded the structure at the time of inspection. While snow limited access to some lower exterior sections, it also clearly revealed wildlife movement patterns around the home.
Customer Concern
The homeowner reported seeing mice inside the house, with activity occurring in multiple areas. Concerns included droppings and ongoing movement within interior spaces.
The issue had become more noticeable during the winter season.
Inspection & Findings
Richard began with a full exterior inspection to identify potential rodent entry points before implementing interior treatment.
Multiple structural gaps were observed around:
- Window and door framing
- Foundation transitions
- Deck and ground-level structural connections
- Exterior trim junctions
Photographs show visible gaps along foundation lines and around window framing where building materials have separated over time. In several areas, openings were present at ground level where rodents could access wall cavities.
Snow coverage provided clear tracking visibility. Distinct animal tracks were visible around the perimeter of the home. Paw prints consistent with squirrel and raccoon activity were observed near deck bases and along the structure. While these species were active on the property, the confirmed interior issue was mice.
Interior photos show small, dark droppings on window ledges consistent with mouse activity.
Cause Analysis
Century homes commonly develop structural gaps as building materials expand, contract, and settle over decades. Even small openings along foundations, siding transitions, and window framing can allow mice to enter.
During winter, rodents actively seek heated interior spaces for shelter. Snow accumulation can drive mice toward accessible foundation-level openings. The combination of structural aging and seasonal pressure likely contributed to interior access.
Treatment / Removal
Richard initiated interior rodent control using tamper-resistant bait stations placed in appropriate locations throughout the home.
The stations contained commercial-grade rodenticide designed for repeated feeding. Mice consume the bait over multiple feedings and typically either leave in search of water or return to nesting areas, where mortality occurs.
All bait placements were conducted by a licensed exterminator and in compliance with Ontario Ministry of the Environment regulations.
This visit marked the beginning of the treatment program.
Exclusion & Repairs
Due to the number of structural vulnerabilities identified, the home will require professional exclusion work to properly seal rodent-sensitive entry points.
Areas requiring sealing include:
- Foundation gaps
- Window and door framing separations
- Deck-to-structure connections
- Ground-level openings
Because of snow accumulation at the time of service, certain areas were partially obstructed. A follow-up exterior sealing plan was recommended once conditions allow full access.
Outcome & Confirmation
Interior baiting was completed during this initial visit. Active mouse presence was confirmed and treatment was deployed.
The homeowner was advised that activity may continue temporarily as the rodenticide takes effect. Monitoring of bait consumption and interior activity will determine next steps.
At the time of service completion, treatment had been successfully initiated in accordance with provincial guidelines.
Technician Notes
Richard confirmed active mouse droppings inside the home.
Exterior inspection revealed multiple accessible gaps consistent with rodent entry in a structure of this age. Snow conditions allowed clear visibility of wildlife traffic patterns around the property.
Interior bait stations were installed safely and securely. Further structural exclusion is recommended to prevent re-entry after population control is achieved.
