The Beaches Utility Pipe Exclusion

Case Study: Rats Burrow Through Basement in the Beaches

This article will analyze and recount a case of interior and exterior rat removal in The Beaches that required more than one visit. It will detail the steps taken in exclusion, by the technician, to control and eliminate a rat infestation in a commercial establishment in the beaches. This is located between queen street east and Kingston road in an area the is filled with parks and has direct access to a lake.

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 that there were rats and signs of rats in a commercial property.

The Beaches, East York: Toronto’s Pride and Joy in the East End

The beaches are a well-known part of Toronto famed for their beautiful beaches. The part of the lake is safe to swim in and attracts people from all around the city. The average age in the beaches is 40 years old and it is a very up-and-coming location. The east York beaches were originally a forest by a swamp. There was no sand and the water was murky. In the 1900s the shoreline was purchased by the Toronto Harbour Commission who cleared the area of trees and built a boardwalk that opened in 1932. While the area is famed for its restaurants the proximity to water and the various parks make it an area of active rodents and wildlife. 

Exterior Inspection 

When the technician arrives on site they will perform an exterior inspection of the outside of the house. The technician will be looking for possible damage that could be an entryway for rats to get into the premises. The exclusion inspection found two wall vents that were open to entry.

Interior Inspection 

The inspection found the basement to be have developed a few vulnerabilities. A waterproofing sheet in the basement was lifted to reveal a large number of rat burrows. This lead the technician to find that the rats are entering the structure through the dirt under the waterproofing sheet. Exclusion would be required to seal up an area of roughly ten to fifteen feet with black flashing in order to prevent rat entry through the soil. The technician also found another three-foot gap in the basement of the commercial property that needed to be closed to prevent rats from burrowing inside.

Rat Entry Point in Wall
Holes like this one allow rats to migrate from the interior of the wall to the inside of the building.
Basement Wall Rodent Entry Points
The entire length of this wall would need to be excluded to stop the spread of rodents.
Rat Entry Point in Wall
All gaps would need to be sealed. Rats can fit through gaps merely 3/4 of an inch wide, so every potential opening must be excluded.

Initial Measures

Baiting on the exterior was organized to treat the exterior rats. An entry hole was found in the basement of the premises. Snap traps were set up in the basement and were baited. This prevents rats from dying inside of a wall which can cause sever issue with health and structural safety. Glue boards were also implemented in the treatment.

Snap Traps Along Walls
Snap traps are effective for interior infestations. Once a rat has been trapped, the trap can be cleaned and re-used.

Proposed exclusion

The dirt entryway in the basement was sealed using black flashing. The process was effective in preventing the rats from entering. Exclusion of an exterior ground opening, 3 feet in size was completed to prevent entry.

Waterproofing Basement Wall Rats
The waterproofing along the basement walls had been compromised and needed to be re-installed with mesh to stop the movement of rats.

Conclusion 

The technician excluded the garage-shed fully from the inside and attached a one-way rat door to the foundation gap. The rat issue was severe but after extensive exclusion and commercial grade rodenticide treatments the rats have been exterminated from the property and the home is now safe from a rodent invasion.
