Job Overview
Location: Guelph, Ontario
Structure: Two-story detached house
Problem: Squirrels entering the attic and beneath the foundation, with additional rat activity identified during the inspection
Service: Humane squirrel removal, wildlife exclusion, and exterior rat control
Visits: 2
Summary
We responded to a report of squirrel activity in the roof of a two-story detached home in Guelph. During the inspection, our team confirmed squirrels were using both the attic and openings along the foundation. Additional evidence of rat activity was also identified around the exterior of the property. A humane removal plan was implemented using one-way doors, followed by extensive exclusion work and an exterior rat treatment program.
Background / Property Context
The home featured multiple accessible gaps at ground level where siding met the foundation. These openings provided sheltered entry points for squirrels moving beneath the structure. During the inspection, additional signs consistent with rodent activity were observed around the exterior foundation, requiring a combined wildlife exclusion and rodent control approach.
Customer Concern
The homeowner was hearing scratching and movement coming from the roof and was concerned that wildlife had entered the attic. They also wanted to ensure the property was protected against any future animal entry.
Inspection & Findings
Technician Andrew completed a full exterior inspection and confirmed squirrel activity within the attic as well as beneath sections of the foundation. Evidence of rat activity was also identified around the exterior of the home.
The inspection found multiple gaps where the siding and foundation met, creating accessible entry points. The photos show foundation openings beneath the siding, a one-way door installed over an active entry point, galvanized steel mesh being installed along the foundation, and completed exclusion work covering the vulnerable areas. Additional images show weighted tamper-resistant bait stations positioned around the exterior as part of the rodent treatment program.
Cause Analysis
Small gaps between the siding and foundation can develop over time as building materials settle and weather. These concealed openings provide protected access beneath structures, making them attractive to squirrels seeking shelter. Once wildlife establishes regular travel routes, the same openings may also be used by rodents if left unprotected.
Treatment / Removal
During the initial visit, our team installed two one-way doors at active foundation entry points, allowing the squirrels to leave while preventing re-entry.
To address the additional rodent activity, an exterior rat treatment program was also completed using two large weighted tamper-resistant bait stations placed around the property. The treatment was performed by a licensed exterminator in accordance with Ontario Ministry of the Environment guidelines.
Exclusion & Repairs
To prevent future wildlife access, we completed the following exclusion work:
- Installed two one-way doors at active foundation entry points.
- Sealed approximately nineteen feet of siding gaps and foundation openings using galvanized steel mesh.
- Sealed three utility line penetrations using galvanized steel mesh and exterior-grade caulking.
- Installed two large weighted tamper-resistant bait stations for ongoing exterior rat control.
Outcome & Confirmation
At the follow-up visit, the homeowner reported no further noises or wildlife activity. We confirmed the squirrels had successfully exited, removed the one-way doors, permanently sealed the remaining entry points, and inspected all completed exclusion work. No further wildlife activity was reported, and the homeowner was satisfied with the completed service.
Technician Notes
The inspection identified both wildlife and rodent concerns requiring separate but coordinated solutions. Foundation-level exclusion was completed using durable galvanized steel mesh to protect vulnerable openings, while exterior rat control addressed rodent activity around the property. The completed exclusion work significantly reduced the risk of future wildlife entry.
