The Bug Blog – Best Pest Control in the Greater Toronto Area

In 2025, pest pressures in Toronto continue to rise due to mild winters, dense housing developments, and increased food availability in residential and commercial areas. This blog will provide a comprehensive guide to the biggest pest problems in Toronto in 2025 and explain how TSR Pest Control’s expertise, proven methods, and humane practices can help residents protect their properties year-round.

This resource is designed to be in-depth, helping Toronto homeowners and businesses understand the threats they face while showing why TSR Pest Control is the trusted choice for long-term pest management.

Why Pest Problems Are Increasing in Toronto

1. Climate Change and Milder WintersToronto has seen steadily milder winters over the past decade. Warmer temperatures allow pests like rats, mice, and raccoons to survive and reproduce at higher rates. Insects like cockroaches, ants, and wasps are also appearing earlier in the spring and persisting longer into the fall.

2. Dense Housing and ConstructionNew developments and urban expansion create fresh opportunities for rodents and wildlife. Construction often disturbs natural habitats, forcing animals like skunks, raccoons, and squirrels to seek shelter in homes, attics, and sheds.

3. Increased Food SourcesGarbage bins, composters, and improperly sealed food waste provide an endless buffet for urban pests. Restaurants, condos, and high-rises, in particular, struggle with rodents and cockroaches due to the concentration of food waste in small areas.

4. Lack of Preventive MeasuresMany property owners don’t realize that proactive pest-proofing is far cheaper and more effective than reacting to an infestation. By the time noises in the attic, scratching in the walls, or droppings on the floor are noticed, the infestation is already well established.

The Biggest Pest Problems in Toronto in 2025

1. Rats in Toronto

Rats have become one of the most urgent pest control challenges in Toronto. Calls for rat extermination have surged in recent years, especially in older neighborhoods with aging sewer systems and dense housing.

• Why Rats Are a Problem in 2025
  • Rats adapt quickly to urban environments.
  • Warmer winters mean more rats survive and breed year-round.
  • Toronto’s aging sewer infrastructure provides perfect nesting and travel routes.
• Common Rat Infestation Signs
  • Droppings in basements, kitchens, or garages.
  • Gnaw marks on wires, wood, or food packaging.
  • Grease marks or “rat runs” along walls.
  • Scratching or squeaking sounds at night.
• How TSR Pest Control Helps
  TSR specializes in comprehensive rat control. Unlike DIY traps or poison alone, TSR uses a multi-step process:
  1. Detailed inspection to identify entry points and nests.
  2. Exclusion work to seal off gaps, cracks, and openings.
  3. Targeted trapping and baiting that eliminates rats quickly and humanely.
  4. Follow-up monitoring to ensure the infestation is fully resolved.

TSR’s lead rat control specialist, with decades of experience, knows Toronto’s rat behavior inside and out — from sewer burrows to roof entry points — ensuring effective results.

2. Mice Infestations

Mice remain a top issue across Toronto homes, especially in suburban neighborhoods and high-rise buildings.

• Why Mice Thrive in Toronto
  • Small size allows them to squeeze through gaps as small as a dime.
  • Reproduce rapidly (a single pair can lead to hundreds in a year).
  • Attracted to stored food, crumbs, and pet food.
• Health and Safety Risks
  • Contamination of food and surfaces with droppings and urine.
  • Potential spread of diseases like salmonella.
  • Fire risk from chewing electrical wiring.
• TSR’s Mouse Removal Approach
  TSR provides long-term mouse control, not just temporary fixes. Their process includes:
  • Inspection of kitchens, basements, attics, and garages.
  • Sealing of cracks, vents, and foundation gaps.
  • Strategic placement of traps for fast results.
  • Guidance on food storage and sanitation practices.

3. Raccoons

Toronto has long been known as the raccoon capital of North America, and in 2025, raccoon problems are as serious as ever.

• Why Raccoons Are a Top Issue
  • Extremely adaptable and intelligent.
  • Skilled at breaking into attics, soffits, and chimneys.
  • Attracted to garbage bins and composters.
  • Known to cause severe property damage while denning.
• Common Entry Points
  • Soffits (25%)
  • Roof vents and plumbing mats (23%)
  • Shingle and roof plywood (15%)
  • Chimneys (12%)
  • Gaps in siding/fascia (10%)
  • Wall vents (8%)
  • Dormer sidings and attic windows (7%)
• Risks of Raccoon Infestations
  • Chewed wires leading to fire hazards.
  • Structural damage to roofing and insulation.
  • Raccoon roundworm, which can infect humans.
• TSR’s Raccoon Removal Services
  TSR offers emergency same-day raccoon removal and uses humane one-way doors whenever possible. Baby raccoons are safely relocated to heated reunion boxes outside, ensuring the mother can recover them naturally. TSR also provides raccoon-proofing services to keep homes secure long-term.

4. Squirrels

Toronto’s many parks and tree-lined neighborhoods make squirrel intrusions a frequent issue, especially in attics.

• Why Squirrels Are a Problem
  • Constantly chewing to wear down teeth, often on wires and wood.
  • Nesting in attics, insulation, and wall cavities.
  • Noisy, especially in the early morning.
• TSR’s Squirrel Removal Process
  TSR uses humane exclusion devices to allow squirrels to exit without returning. Attics are inspected for damage, and baby squirrels are safely reunited with mothers. TSR also strengthens vulnerable roof areas to prevent re-entry.

5. Skunks

Skunks in Toronto often burrow under decks, sheds, and porches, creating strong odors and structural concerns.

• Signs of Skunk Activity
  • Persistent skunk odor near the property.
  • Burrow holes or soil disturbance under structures.
  • Tracks and droppings.
• TSR’s Skunk Removal Services
  TSR specializes in underground trenching and barrier installation to prevent burrowing. Humane skunk removal and exclusion keeps decks and sheds secure.

6. Wasps and Hornets

During Toronto’s summer months, wasps and hornets become aggressive and dangerous pests.

• Risks of Wasps
  • Painful stings that may trigger allergic reactions.
  • Colonies that can contain thousands of stinging insects.
  • Nests built in attics, wall voids, or trees.
• TSR’s Wasp Removal Services
  TSR offers safe wasp nest removal and treatments that eliminate colonies without risking homeowner safety.

7. Ants

Carpenter ants, pavement ants, and pharaoh ants are common invaders in Toronto.

• Carpenter Ants – Damage wood structures while tunneling.
• Pharaoh Ants – Difficult to eradicate due to multiple colonies.
• Pavement Ants – Create mounds in driveways and patios.

TSR Ant Control involves identifying the specific species and using targeted treatments to eliminate colonies at the source.

8. Bed Bugs

Bed bug infestations remain a serious issue in Toronto apartment buildings, hotels, and condos.

• Signs of Bed Bugs
  • Small red bites in clusters.
  • Blood spots on sheets.
  • Live bugs in mattress seams or furniture.
• TSR’s Bed Bug Treatments
  TSR uses professional heat and chemical treatments for total elimination. DIY sprays are rarely effective against widespread infestations.

9. Birds

Birds such as pigeons, starlings, and sparrows often nest in vents, eaves, and ledges.

• Problems Caused by Birds
  • Droppings that corrode building materials.
  • Clogged vents creating fire hazards.
  • Spread of mites and parasites.
• TSR Bird Removal Services
  TSR installs bird-proofing solutions like vent covers, spikes, and screening to stop nesting. Humane methods ensure no harm to the birds.

10. Cockroaches

Cockroach infestations are particularly common in Toronto’s high-rise apartments and commercial kitchens.

• Health Risks
  • Carry bacteria and pathogens.
  • Trigger asthma and allergies.
