Case Study: Squirrel Removal and Mouse Treatment in Forest Hill

This case study details a squirrel removal and mouse extermination in Forest Hill. The initial call to the property was for sounds being heard between the bedroom and attic. The technician was sent to inspect the attic for signs of mice occupation and then to exclude the roof and treat the mice inside. The customer was aware of sounds and smells coming from the attic and wanted the situation dealt with.

Forest Hill, Old Toronto

Forest hill was a former village in mid-town Toronto that was amalgamated into the city as late as 1967. Because of this the part of the city so named is very independent, and has kept their name of forest hill. This area is very wealthy and contains some of the largest houses in the city. Like Bridal Path, this part of the city houses Toronto’s elite. Though in 1971 this area would have been ripped asunder by a plot to build a Spadina express-way, likely destroying many old houses and ruining a very high class area forever. This people of forest hill and the Annex protested en mass until the government pulled out of the plan. The beauty of the city once more maintained.

Exterior Inspection

The initial inspection of the roof and property found multiple openings on and around the roof as well as accessible roof vents and three foundations gaps and three roof-soffit intersections that could all allow mice or other animals into the home. Exterior tamper-proof bait stations containing commercial-grade rodenticide were recommended to quell the exterior mouse issue on the property. The mouse issue led to the discovery of an opening on the side of the house that could allow squirrel entry. A two-man crew was sent to inspect.

Wall Vent Mouse Entry Point
Rodents can chew through wall vents, like the one on the side of this property. From here, they can reach the walls of the home and nest in the insulation.
Crack in Bricks Mouse Entry Point
Weep vents, cracks in the foundation, and gaps between bricks present mice with an opportunity to nest indoors.

Interior Inspection

The interior inspection for the attic found mouse feces in the attic and insulation. No dead animals were found. The attic was then treated with tamper-proof bait stations containing commercial-grade rodenticide, placed in areas of high activity. The inspection of the first attic found very little in the way of activity of mice. However the customer recalled a second two story attic that did have signs of mice but no signs of larger animal occupation. While the mouse treatment was being deal with the activity in the attic was still apparent. The customer requested a squirrel inspection requiring a two man crew in order to scale the cedar roof of the house. This was assured with the discovery of a hole in the insulation of the second attic.

Roof-Soffit Intersection Squirrel Entry Point
First, the technicians observed the exterior of the roof. Roof vents and soffits are prone to squirrel break-ins.
Attic Insulation Damage
The insulation in the attic showed signs of damage, indicating a pest problem. Burrowing holes and mouse feces were found in the insulation.

Initial Measures

The initial measures taken by the technicians upon discovering an entry way for squirrels was to exclude the south side and to attach a one way door to allow the squirrel to humanely vacate the attic. The mouse treatment both in the main attic and the two floor attic outside of the house was effective in quelling the mouse infestation. Two exterior rodent bait station that are weighted and tamper-proof containing commercial grade rodenticide were placed on the property.

Rodent Bait Station
Bait stations are highly effective at suppressing exterior rodent populations.
Wall vent Exclusion Toronto
Our wall vent covers are affordable and come with a 2-year warranty. Rodents cannot squeeze through the gaps, nor can they chew their way through.

Proposed Exclusion

The proposed exclusion by the technician was to seal off four wall vents using rubber coated waterproof galvanized steel cages along with a fifth wall vent of a larger size. The foundation gaps were sealed with concrete and silicone and three feet of soffit were sealed with waterproof galvanized steel mesh. A one way door used to humanely evict a wild animal from an attic or other enclosure was attached and the area surrounding it and the area was excluded with waterproof galvanized steel mesh.

Conclusion

In conclusion, the initial discovery of the mouse infestation led to the inspection of the second attic were a wild animal was found. By listening to the customers and planning treatments carefully the customers various issues from a mouse infestation to a squirrel occupying her attic were resolved. The squirrel and the mouse infestation have been resolved.
