Job Overview
Location: Guelph, Ontario
Structure: Two-story detached house
Problem: Squirrel activity reported in the attic and roof system
Service: Humane squirrel removal and wildlife exclusion
Visits: 2
Summary
Our team completed a two-visit squirrel removal service at a detached home in Guelph after the homeowner reported persistent activity in the attic. During the inspection, we confirmed squirrel access through damaged roof ventilation components and additional vulnerable wall vent openings. Humane one-way doors were installed to allow the animals to leave safely while preventing re-entry. Once activity had ceased, all temporary devices were removed and the identified entry points were permanently secured with galvanized steel exclusion materials.
Background / Property Context
The property is a two-story detached home with multiple roof and wall ventilation openings. Several roof vents showed visible damage consistent with wildlife chewing, creating suitable access points into the attic. The surrounding neighbourhood also provides mature trees that allow squirrels convenient access to the roof.
Customer Concern
The homeowner reported hearing squirrel activity in the attic and requested a permanent solution that would safely remove the animals while preventing future entry.
Inspection & Findings
Technician Andrew completed a full exterior inspection and confirmed active squirrel entry into the attic.
Inspection identified:
- A damaged roof vent with visible chewing that had created an opening into the attic.
- Additional vulnerable roof vents requiring protective screening.
- Multiple wall vents that required wildlife-proofing.
- Active squirrel travel routes on the roof consistent with the reported attic activity.
The photographs show damaged roof vent material, temporary one-way doors installed over primary exit points, galvanized steel vent cages protecting roof and wall vents, and completed exclusion work following removal of the temporary devices.
Cause Analysis
Squirrels commonly exploit damaged roof vents and other exterior openings to access attic spaces for shelter and nesting. Roof-mounted plastic vent covers are particularly vulnerable once they become weathered or are repeatedly chewed. Homes with multiple roof and wall vents require all accessible openings to be secured to reduce the likelihood of future wildlife entry.
Treatment / Removal
During the first visit, Andrew confirmed squirrel activity and installed humane one-way doors over the primary entry points, allowing the animals to exit without re-entering the structure.
Additional exclusion work included:
- Installation of two one-way doors over damaged wall vent entry points.
- Installation of galvanized steel protective cages over four roof vents.
- Installation of galvanized steel protective cages over three wall vents.
- Reinforcement of one plumbing vent using galvanized steel mesh.
Exclusion & Repairs
Once monitoring confirmed the squirrels had left the attic, our team returned for the scheduled follow-up visit. The temporary one-way doors were removed, the former entry points were permanently sealed, and all exclusion work was inspected to verify it remained secure.
The galvanized steel vent protection provides a durable barrier while maintaining normal ventilation throughout the home.
Outcome & Confirmation
At the second visit, the homeowner reported no further sounds or signs of squirrel activity. We confirmed the one-way doors could be safely removed, completed the final sealing of the entry points, and inspected all exclusion repairs. No further wildlife activity was reported following completion of the work.
Technician Notes
Andrew confirmed squirrel activity during the initial inspection and identified damaged roof vent components as the primary access point. Temporary one-way doors were installed to allow humane removal, followed by comprehensive vent protection using galvanized steel cages and mesh. At the follow-up visit, no additional activity was observed, the one-way doors were removed, and the completed exclusion system was verified.
