Mouse Treatment and Rodent Exclusion in Toronto

The initial call to the property was for an ongoing mouse issue in the customer’s home. So consistent that the customer researched how to stop it permanently and expressly requested rodent exclusion to end the infestation permanently.  When you live near any sort of park or ravine it is common for mice or rats to venture onto your property. They may not stay if they do not find what they want. What they want is food and in the case of rats, water as well. European house mice have been with humanity for thousands of years and know how to enter our homes easily and access our kitchens with guile. Getting rid of them is more than treating the infestation it is preventing it.

Exterior Inspection 

The initial inspection of the home revealed a number of foundation gaps that had been sealed off by the customer. This sort of proactive activity is both helpful and dangerous. Sealing entryways when you don’t really know if it is an entry or an exit can actually trap rodents in the house. Leaving the work to the professionals will ensure you have the right opening sealed at the right time.

Foundation Access
Masonry of this type does not use mortar to seal the bricks to the ground. rats are strong enough to move the bricks and access the foundation underground. This will prevent them from doing this in the future.
The Back Yard
The backyard of the property has many places for rats to burrow and hide. Paving stones and concrete that has aged are easy for rats to breakthrough.
Detritis
A large amount of detritus on the property makes it very easy for rats to hide. Mess is a rodent’s best friend.
Pluming Vent
Open wall and plumbing vents are easy to access points for rodents to enter your home directly. This can result in dead rats in your walls and an interior infestation that is much harder to treat.
Weep Vents and Foundation Gaps
Foundation gaps and weep vents are accessible to most rodents from mice to rats of smaller size. Foundation gaps can be enlarged by them to create an access point into the home.

Interior Inspection

The initial inspection of the inside of the home revealed extensive activity in the basement and the kitchen. This is common as house mice know where to hide to prevent their discovery by humans. Seeing a single mouse is an opportunity. They work so hard to be invisible when you finally see one you will know the infestation is serious.

Initial Measures

The initial measures are taken by the technician treatment of the interior house mice via tamper-proof bait stations containing commercial-grade rodenticide. This is an anti-coagulant poison that causes the mice to taste it, feel no sickness and then repeatably consume it until they desiccate entirely. This makes it safe for them to die in walls and makes the treatment much less gruesome.

Proposed exclusion

The proposed exclusion by the technician was extensive. The porch needed to be trenched and excluded as part of the process to rid the customer of their long-term mouse issue.  Trenching is a process where a one-foot by a six-inch trench is dug around the accessible perimeter of the deck, porch or shed. The deck is then sealed off using various gauges of galvanized waterproof steel mesh or in this case with flashing. The flashing is attached to the top of the edge of the deck or porch and to the bottom of the shed and then is buried one foot down into the ground and six inches out. This process protects decks, sheds and porches from animal and rodent invasion. The technician also sealed off thirteen feet of an area of the roof called the drip edge. This area is where your shingles meet the edge of the roof and are very open access points for both skilled rodents and squirrels. Wild animals can enter through this opening and get into the attic. This area was also sealed off with thirteen feet of waterproof galvanized steel mesh.

Foundation Access
By sealing this area off with galvanized steel mesh the technician is preventing the rats from accessing the foundation by moving the masonry.
White Flashing
When an area can be accessed like the side of the house through masonry and underground the best preventative measure is to exclude the area with steel mesh or flashing. In this case, white flashing was used for aesthetic reasons.
Stair Case
The wooden stairs had a number of gaps and openings that would allow rodents to burrow beneath them. Sealing it off with white flashing prevents their access.

Conclusion 

In conclusion, The customer’s mouse issue was resolved and will no longer plague him now that the areas they can access are sealed off and obstructed. The customer was pleased with the result and has not had an infestation since.
