Toronto, Ontario – 2024
This article will analyze and recount a case of a severe mouse infestation in a house in Toronto, Ontario. This house suffered years’ worth of infestations, and while treatments kept getting done, the mice continued to come back every season. The solution to the problem of repeated infestations is to find where the mice are getting into the house and to seal those areas permanently.
This visit is located between Gerrard Street East and Dundas Street East in East York located in Toronto, Ontario.
The technicians, before the work is done, must first inspect and confer with the customer or customers on the issue and then must inspect for the source of the infestation. This was due to a large area of the siding being accessible to rodents. The gaps in the siding were large enough that the technician could fit his hand into the openings, and for a mouse or even a rat, that is a guaranteed access point. The goal of the work was to seal those entry ways to prevent rodents from accessing the home’s interior.
Toronto, Ontario: The Six
Toronto is Canada’s biggest city and Ontario’s capital city. It’s the 4th most populated city in all of North America. It’s the heart of the Golden Horseshoe and the centre of the Boreal Forest. It was built around the most beautiful parts of Lake Ontario with a bustling population of more than 9.7 million people. Toronto is famous for its thriving business district, the arts and fashion, sports, and astounding culture. It’s a melting pot of diversity and cosmopolitanism. Indigenous people have lived in and used this region to gather for thousands of years.
Exterior Inspection
When the technician arrived on site, they performed an exterior inspection of the property and found a large number of entryways. The siding that had been installed on the exterior of the house was not installed properly and left a huge amount of space between the siding and the wall, which allowed for rodents to get into the house itself. There were thirty feet of siding gaps all around the exterior of the house that were easy access for rodents. These gaps would need to be sealed to prevent mice and rats from getting into the home. Foundation gaps were also found, allowing rodents to enter the foundation. While open doors can also allow rodents to enter a house, in this case, there was an actual gap in one of the doors. Mice did not need the door to be open; they could slip through that gap to get into the house very easily.

Interior Inspection
While inspecting the interior, I found a great deal of rodent activity. There was the presence of faces in a large number of areas and a smell that was clearly mouse-related. The smell that mice can make is from their urine. While mice can die in the walls of the house, their moisture content is low, and they tend not to make a smell. Rats, however, do tend to make a very strong smell when they die in the walls as they have a terrible diet and a very high water content. Bait on the interior of a house for rats is something you should not do. Snap traps are best to prevent the rats from dying in the walls, and then bait should be placed on the exterior.
Initial Measures
The first step was to find the entry ways the mice were getting into. This included thirty feet of siding gaps, a foundation gap that could allow rodents to enter the foundation as well as a gap in a door frame that mice could enter easily. These areas needed to be sealed to stop rodents from getting into the house and end the repeated seasonal infestation of mice every year.
Proposed exclusion
The technician sealed off thirty feet of siding gaps that rodents could use to enter the home. Siding gaps may not seem like a problem, but behind the siding is nothing but plywood, which can be easily chewed through and often has openings that rodents can get through without having to make a new hole. There was also a foundation gap that was accessible as well as a door frame that was accessible to mice. Mice are very small animals and can enter through an opening as small as a quarter. Sealing these areas off is the most important step in stopping rodents from getting back into the house. A treatment will kill the rodents that are there, but if the areas they can enter are not sealed, no amount of commercial-grade poison will be enough to treat the onslaught of rodents getting into the house.



Conclusion
The technician excluded all the openings, and after the work was completed and the current infestation treated, the customers never saw another mouse in their home again. The work was successful, and the effect was dramatic. The customers were very happy and were now free from mice.
