Why They Thrive & How to Stop Them

If you’ve ever spotted a rat darting across a subway platform or scurrying near the transit system, many urban environments, like those found in cities, provide an ideal habitat for rodents. The combination of constant food availability, shelter, and minimal natural predators creates a perfect storm for rat and mouse populations to flourish underground.

Toronto has been identified as Canada’s “rattiest” city, a title attributed to factors such as document and ongoing construction projects that disrupt rodent habitats, forcing them into public spaces, including transit systems.

In this blog, we’ll delve into the research on rodents’ prevalence in ways and transit systems, the challenges they pose, and the measures being taken to address this issue.

Rodents and Big Cities: A Universal Problem

Rodents are not just a Toronto issue—they’re a common sight in major cities around the world. Subways and underground transit systems from New York City to London and Paris have long battled rodent infestations. These systems provide everything rodents need to survive: warmth, food scraps, moisture, and countless hiding places.

Here’s why this is a global urban issue:

• Abundant Food Waste
  Transit systems see millions of passengers daily, many of whom eat on the go. Even a few dropped crumbs or an unsealed garbage bin is enough to feed rodents—and there’s a constant supply.
• Shelter from Weather and Predators
  Underground tunnels, crawl spaces, and utility rooms offer rodents protection from predators, freezing temperatures, and extreme weather—making them ideal nesting locations.
• Minimal Disturbance
  Many maintenance and service areas are rarely accessed by humans, giving rodents the privacy they need to breed and travel undetected.
• Efficient Travel Routes
  Subway systems are laced with interconnected circuits and tracks. These act as rodent superhighways, allowing them to move and spread without ever having to go above ground.

Toronto Is Not Alone

New York City spends millions annually on rat control, and London has implemented special patrols and baiting programs to reduce sightings in its Tube system. When we see rodents in Toronto’s TTC system, it’s not a sign of failure—it’s a sign of a shared urban challenge that requires a thoughtful, multi-layered response.

Why Toronto’s Subway and Transit Systems Attract Rodents

Toronto’s subway and transit systems provide an ideal environment for rodents, including rats and mice. Such environments offer everything rodents need to survive and multiply: food, shelter, warmth, and easy access routes.

Key Factors Contributing to Rodent Infestations in Toronto’s Transit Systems:

• Abundant Food Sources
  With thousands of commuters daily, food waste is inevitable. Crumbs, discarded wrappers, and overflowing garbage bins in stations and on trains provide a constant food supply for rodents.
• Shelter and Nesting Areas
  The subway’s infrastructure—tunnels, maintenance rooms, and storage areas—offers numerous secluded spots for rodents to nest undisturbed.
• Warmth and Moisture
  Underground systems maintain relatively stable temperatures year-round, thereby protecting rodents from harsh weather conditions. Leaking pipes and pooled water also provide necessary hydration.
• Easy Access and Movement
  Rodents exploit cracks, vents, and utility lines to enter and navigate the subway system. The interconnected nature of the transit network allows them to move freely and expand their territory.
• Limited Natural Predators
  The underground environment lacks natural predators, allowing rodent populations to grow unchecked.

These factors, when combined, create a hospitable environment for rodents, making Toronto’s transit systems particularly vulnerable to infestations.

Where Rodents Are Most Common in the System

Rodents have become an increasingly visible presence in the Toronsit system, particularly within the subway network. Their adaptability and the environment provided by the subway infrastructure contribute to their proliferation in specific areas.

Common Rodent Hotspots in Toronto’s Subway System

• Track Areas and Tunnels
  The spaces between subway tracks offer rodents shelter and easy mobility. The darkness and relative quiet during off-peak hours make these areas ideal for nesting and foraging.
• Station Platforms and Waiting Areas
  Food debris left by commuters can attract rodents to platforms. Their presence is often noted during quieter times when human activity is minimal.
• Garbage Disposal Zones
  Areas designated for waste collection, especially if not regularly cleaned, can become feeding grounds for rodents, and food waste is a significant attractant for them.
• Maintenance and Storage Rooms
  These less-frequented spaces provide rodents with undisturbed environments to nest and reproduce.
• Ventilation Shafts and Utility Access Points
  Rodents utilize these pathways to move between different parts of the subway system, easily accessing various levels and areas.

These typical hotspots are typical for implementing effective rodent control measures within the transit system.

The Dangers of Rodents in Transit Systems

Rodents in transit systems like Toronto’s subway aren’t just a nuisance—they pose serious health and safety risks to both passengers and infrastructure.

Health Risks to Passengers and Staff

Rodents are known carriers of various diseases that can be transmitted to humans through direct contact or indirectly via contaminated food, water, or surfaces. Some of the health concerns include

• Disease Transmission: Rodents can spread diseases such as leptospirosis, hantavirus, and salmonellosis. These illnesses can be contracted through exposure to rodent urine, droppings, or saliva.
• Allergic Reactions and Asthma: Rodent allergens can trigger allergic reactions and exacerbate asthma symptoms, particularly in individuals who are sensitive to them.
• Contamination of Food and Surfaces: Rodents often scavenge through garbage and unsanitary areas before entering transit systems, potentially introducing harmful bacteria and pathogens into these environments.

Infrastructure and Operational Hazards

Beyond health concerns, rodents can cause significant damage to transit infrastructure:

• Electrical Damage: Rodents tend to theatrical wires, which can lead to short circuits, power outages, and even fires. This not only endangers safety but also disrupts transit services.
• Structural Damage: Their gnawing can compromise the integrity of various structural components, leading to costly repairs and maintenance.
• Service Disruptions: Rodent-related damages can result in unexpected service delays, affecting the reliability of the transit system and inconveniencing passengers.

Addressing these dangers requires a comprehensive approach that includes regular maintenance, effective waste management, and proactive pest control measures.

Challenges in Rodent Control for Subway Systems

Managing rodent populations in subway systems, such as Toronto’s TTC, presents unique challenges. The underground environment, combined with the movement of passengers and trains, creates a complex environment for effective pest control.

Key Challenges in Controlling Rodents in Subway Systems

• Limited Access to Infestation Sites
  Many areas within the subway infrastructure, such as deep tunnels, maintenance shafts, and utility corridors, are difficult to access. This makes it challenging to identify and effectively treat rodent nesting sites.
• Continuous Human Activity
  The TTC operates nearly 24/7, leaving minimal downtime for thorough cleaning and pest control measures. The constant presence of passengers and staff limits the use of certain controls specific to operational hours.
• Abundant Food Sources
  Despite regular cleaning efforts, food waste from passengers can accumulate, providing a steady food supply for rodents. This abundance of food supports larger rodent populations and complicates control efforts.
• Structural Complexity
  The intricate design of subway systems, with numerous nooks and crannies, offers rodents ample hiding and nesting spots. Sealing all potential entry points is a daunting task that requires a significant amount of time and resources.
• Environmental Considerations
  The use of chemical rodenticides is restricted in many areas due to environmental and safety concerns. This limits the available options for pest control within the subway system.
• Public Perception and Safety
  Visible rodent activity can lead to public concern, resulting in a decline in confidence in the transit system. Ensuring passenger safety while implementing effective rodent control measures is a delicate balance.

Addressing these challenges requires a comprehensive and adaptable pest management strategy that considers the unique characteristics of subway environments.

What’s Being Done: TTC & City Measures to Control Rodents

Toronto’s transit system has long grappled with rodent infestations, prompting both the Toronto Transit Commission (TTC) and city authorities to implement various control measures. These efforts aim to mitigate health risks, infrastructure damage, and public discomfort associated with rodent presence in the subway system.

TTC’s Rodent Control Initiatives

The TTC has adopted a multi-faceted approach to manage rodent populations within its subway system:

• Regular Baiting Programs: Maintenance crews distribute rodenticides at strategic locations, such as the ends of platforms, approximately every four months. This routine helps in controlling the track level.
• Enhanced Cleaning Protocols: Efforts have been made to improve cleanliness in stations and trains, reducing food waste and other attractants for rodents.
• Infrastructure Maintenance: Sealing cracks and repairing structural damages help prevent rodents from entering and nesting within the subway infrastructure.

City of Toronto’s Measures

Beyond the TTC’s efforts, the City of Toronto has implemented broader strategies to address rodent issues:

• Property Standards Enforcement: The city investigates complaints related to rodents on private properties, ensuring that property owners take necessary actions to mitigate the problem.
• Public Health Inspections: Toronto Public Health conducts inspections of food establishments and other high-risk areas to ensure compliance with health regulations that prevent rodent infestations.
• Community Engagement: The city provides residents and businesses with resources and information to prevent and control rodent infestations.

While these measures have had varying degrees of success, the persistent nature of rodent infestations in urban transit systems underscores the need for continuous and adaptive management strategies.

Expert Solutions for Urban Rodent Control
