Job Overview
Location: Toronto, Ontario
Structure: Two-storey Victorian house
Problem: Mouse activity reported inside the home
Service: Interior mouse control treatment and follow-up monitoring
Visits: 3
Summary
Our team responded to reports of ongoing mouse activity inside a two-storey Victorian home. Initial interior treatment was completed, followed by a later return visit when activity reoccurred. Additional baiting and identification of likely exterior entry conditions were addressed. After follow-up service, interior activity was resolved and no further issues were reported.
Background / Property Context
The property is an older Victorian-style home with multiple structural transitions, including siding, foundation interfaces, and exterior architectural details. These features can create small gaps over time that may allow rodents to access interior wall voids if not sealed.
Customer Concern
The homeowner reported mice being seen and heard inside the house, with activity occurring in multiple interior areas.
Inspection & Findings
During the initial visit, mouse activity was confirmed inside the home. A full interior inspection was completed, and potential exterior entry points were discussed with the homeowner.
On the second service visit, renewed interior activity was reported approximately one year later. Exterior inspection identified gaps along siding and lower structural areas that were consistent with possible rodent entry routes.
Photos provided show interior tamper-resistant bait stations in place, as well as exterior gaps along siding, eaves, and foundation-level transitions that could allow rodent access if left unsealed.
Cause Analysis
Older homes often develop small gaps at siding, foundation, and trim interfaces due to age and seasonal movement. These openings can provide mice with access to wall cavities and interior spaces, especially during colder months when rodents seek warmth and food sources. Without permanent exterior sealing, interior treatments alone may not fully prevent re-entry.
Treatment / Removal
Interior mouse control was carried out using tamper-resistant bait stations containing commercial-grade rodenticide. All pest control work was performed by a licensed exterminator in accordance with Ontario Ministry of the Environment guidelines.
During the second visit, interior baiting was renewed and additional monitoring was established to address the active population.
Exclusion & Repairs
During the follow-up visit, a specific siding gap was identified as a likely entry point. Sealing of this area and the placement of a large, weighted exterior bait station were recommended and approved by the homeowner to reduce the risk of further entry and support long-term control.
Outcome & Confirmation
After the third visit, the homeowner confirmed that interior mouse activity had stopped. No further rodent issues have been reported since the completion of the follow-up treatment and monitoring period.
Technician Notes
The initial service and inspection were completed by our technician, with interior treatment installed and entry points reviewed. A subsequent return visit was completed by another member of our team to renew treatment, reassess conditions, and implement additional control measures. Final confirmation was received from the homeowner indicating successful resolution of the issue.
