Job Overview
Location: Markham, Bayview Glen
Structure: Backsplit bungalow with attached garage
Problem: Noises in the attic; suspected squirrel activity with possible mouse presence
Service: Humane squirrel exclusion, roof and vent protection, soffit reinforcement, interior mouse treatment
Visits: 2
Summary
Our team responded to an attic noise concern at a residential backsplit bungalow in Markham. A full exterior and roof inspection identified a concealed soffit entry point used by squirrels, along with secondary vulnerabilities at roof and wall vents. Humane squirrel exclusion was completed over two visits, combined with proactive vent protection and an interior mouse treatment performed by a licensed exterminator in accordance with Ontario Ministry of the Environment guidelines.
Background / Property Context
The property features a multi-plane asphalt shingle roof with several vent penetrations and soffit intersections. Mature trees nearby provided easy roof access for climbing wildlife. Weather conditions were clear and dry during service, allowing for safe roof work.
Customer Concern
The homeowner reported ongoing noises in the attic space. While no obvious exterior damage was visible from ground level, there was concern about squirrels and potential mice inside the home.
Inspection & Findings
During the initial visit, our technician conducted a thorough roof-level inspection. An opening was identified at a soffit intersection consistent with squirrel entry. Multiple roof vents and wall vents were also noted as potential access points. Evidence of animal presence was observed on the roof surface near the entry area. No safety or access limitations were encountered.
Cause Analysis
Soffit intersections and roofline transitions can create small gaps over time, especially on complex roof designs. These areas are attractive to squirrels seeking sheltered nesting space. Once squirrels gain roof access, unsecured vents and weakened soffit materials increase the likelihood of repeated entry attempts.
Treatment / Removal
On the first visit, technician Richard installed a one-way door over the identified soffit opening to allow squirrels to exit without re-entry. Roof vents were fitted with wildlife-proof covers, and wall vents were secured with appropriate vent guards. Animal debris on the roof was cleaned and disinfected. Inside the home, a mouse treatment was completed using approved methods, with bait stations placed and documented in compliance with provincial regulations.
Exclusion & Repairs
The affected soffit area was reinforced to restore structural integrity. Screening and flashing were installed where required to close gaps at roofline transitions and vent penetrations. All materials were fastened securely to withstand weather exposure and wildlife pressure.
Outcome & Confirmation
On the second visit, the one-way door was removed after confirming squirrel activity had ceased. The final entry point was permanently sealed, and all exclusion work was inspected. Interior bait stations were checked to confirm mouse activity was decreasing as expected. No further wildlife activity was reported following completion of service.
