This article will analyze and recount the removal of an interior and exterior rat infestation in a two-unit home in East York. It will detail the steps taken in exclusion and treatment, by the technician, to block off the rat’s access to the house and to treat the rats both on the interior and on the exterior. This is located in Woodbine Ave. And Main St. By the beaches.
The technicians, before the exclusion, must first inspect and confer with the customer or customer’s on the issue and then must inspect for levels of activity. The customer’s original complaint was rat activity both inside and outside of the home. A technician was sent out to inspect for rats and to exclude entryways.

Beach Hill, East York: A Populated And Busy Part Of Toronto
The Beaches are one of the most beloved parts of Toronto. So, beloved, there is a band from that area and with that name: the beaches. This area of Toronto is in east York which is a very green area full of parks. It is also a busy area with the Danforth and hundreds of restaurants very nearby. These restaurants and green spaces can attract rats and other animals to residential homes.
Exterior Inspection
The initial exterior inspection came up with a great deal of information about the activity. There was a preponderance of burrows in the front yard. The back shed was being used by the rats so the customers would have it removed. Foundation gaps and many other locations needing exclusion were found as well as a large number of wall vents and a dryer exhaust pipe. There was a great deal of detritus in the yard that would make a rat presence difficult to treat.

Rat Entry Point Under Shed — Sheds are hot spots of pest activity. Rats, raccoons, and skunks commonly dig underneath them.

Foundation Gap — Like sheds, homes with spaces beneath them present pests with an opportunity to burrow beneath them.

Interior Inspection
The interior inspection found a raised platform in the basement that was allowing rat entrance. This platform holds the washing machine and shows cold spots on the infra-red camera. Rat activity was found inside the basement as well. The recommendation was made to remove the subfloor and install steel mesh beneath it. The area consisted of 54 square feet.

Thermal Camera in Laundry Room — The thermal camera is a handy tool because it can locate nests and rats hiding behind walls and other obstacles.

Thermal Camera for Rodent Inspection — The thermal camera pointed to rat activity beneath the subfloor.

Initial Measures
The technician placed three bait stations on the exterior property as well as snap traps on the interior in the basement where activity was found to be highest. An extra bait station was placed due to the severity of the infestation. A rat door was also recommended to ensure rats could vacate the building but not return. This will help keep the rats outside where they can be treated faster with poison.

Rodent Bait Station in Basement — Bait stations are usually placed outside to avoid the presence of dead rats within the walls or floor of the home. In this case, a bait station was placed in an area of high activity.

Rodent Bait Station Outside — Rodents become sick after ingesting bait a few times. When they begin to feel ill, they retreat into their burrows to perish. This is the most effective method of rodent control.

Exclusion
The front of the home and the underside of the porch were excluded to prevent rats from entering the home. Wall vent covers were also installed over open vents to limit rat access to the house while the exterior is treated. The installation of a rat one-way door allows rats that are already inside the home to vacate to their burrows but prevent them from re-entering the home. This is to ensure that the rats leave the home so they can be treated more rapidly with exterior bait stations. Areas on the side and back of the home were excluded using various materials like galvanized steel mesh and silicone gap sealer. Rat burrows near the home were closed off with gravel to prevent the rats from building more burrows near or under the house.

Rat One-Way Door Davisville — The one-way door let rats out where they would consume the bait placed outside.

The interior exclusion involved the demolition of a raised section of the basement floor where laundry machines sat and where rat activity was found. The floor was demolished and then galvanized steel mesh was installed on the open soil. A large hand-made rat one-way door was then installed in the basement to ensure the rats burrowing under the basement are evicted.

Subfloor Opened in Basement Rat Burrows — Opening up the subfloor revealed mass amounts of rodent activity. Once opened, exclusion could take place.

Basement Subfloor opened Rat Burrows — The rats in this case burrowed from the outside into the basement sub-floor.

Subfloor Exclusion Galvanized Steel Mesh — Galvanized steel mesh was laid down on the floor and screwed into the walls to stop any rats from entering the basement.

Laundry Room Subfloor Exclusion — Rats cannot chew or claw through this material, making it impossible for them to reach the inside.

Galvanized Steel Mesh Rat Exclusion Basement Subfloor — Once the mesh was installed, the homeowners could have their floor replaced.

Deck Rat-Proofing Outside — Outside, the edges of the deck were excluded with mesh.

Wall Vent Rodent-Proof Mesh — Wall vents were covered with mesh as well. A comprehensive exclusion of the exterior was performed so that no more rats could make it inside.

Foundation Gaps Excluded Mesh — The gaps along the side of the house were also excluded.

Pest-Proof Deck Galvanized Steel Mesh — Pest-proofing the deck, the sides of the home, and the wall vents would keep pests from burrowing into the house again.

Mesh Exclusion Side of House — The Exterminators’ pest-proofing services come with a 2-year warranty. If pests break through, we will come back and fix the problem at no additional cost.

Conclusion
The extensive exclusion was successful and halted the ingress or rats into the building. The exterior bait stations were effective in killing off the exterior population. The house is protected through extensive exclusion and a rat one-way door, which will ensure that rats on the inside can leave but not get back in. The washing machine platform was removed and areas around it excluded. The basement demolition and exclusion were highly effective in getting the rats out of the basement and basement walls. The exterior rat doors were highly effective in allowing the rats to exit the property. The performed exclusion then kept them out for good.
