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. 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. 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. 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. 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. 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.
