Rats are one of the most destructive and dangerous pests affecting homes and businesses in Calgary. Unlike mice, rats are larger, more aggressive, and capable of causing serious structural damage in a short period of time. If you suspect rat activity in your property, acting quickly is critical.
In this guide, we’ll explain the warning signs of a rat infestation, the risks they pose, why DIY methods often fail, and how professional rat control in Calgary eliminates the problem safely and effectively.
Why Rat Infestations Are Increasing in Calgary
Urban development, construction projects, and seasonal weather changes all contribute to increased rat activity. As temperatures drop, rats actively seek warm indoor spaces with easy access to food and water.
Common reasons rats enter properties:
- Gaps in foundations and siding
- Open vents and damaged screens
- Poor garbage storage
- Sewer line access
- Food left accessible in garages or kitchens
Once inside, rats reproduce quickly and are extremely difficult to eliminate without professional intervention.
Common Types of Rats Found in Calgary
Norway Rat (Brown Rat)
- Most common in urban areas
- Larger body and blunt nose
- Often found in basements and lower levels
- Strong burrowers
Roof Rat (Less Common)
- Smaller and more agile
- Prefers higher areas like attics
- Excellent climbers
Identifying the species helps determine the most effective treatment plan.
Signs of a Rat Infestation
Rats are primarily nocturnal, meaning activity often happens at night.
Warning Signs Include:
- Loud scratching or gnawing noises in walls or ceilings
- Large droppings (bigger than mouse droppings)
- Grease marks along walls
- Chewed wires or wood
- Burrows around foundations
- Foul odors from nesting areas
If you see one rat during the day, the infestation may already be advanced.
Health Risks Associated with Rats
Rats pose serious health concerns for families, employees, and customers.
Diseases Spread by Rats:
- Leptospirosis
- Salmonella
- Hantavirus
- Rat-bite fever
Rats contaminate food and surfaces with urine, droppings, and hair. In commercial environments, infestations can lead to health code violations and reputational damage.
Property Damage Caused by Rats
Rats constantly gnaw to keep their teeth from overgrowing.
Damage May Include:
- Chewed electrical wiring (fire hazard)
- Structural wood damage
- Insulation destruction
- Flooding from chewed plumbing lines
- HVAC contamination
The longer rats remain untreated, the more expensive repairs become.
Why DIY Rat Control Often Fails
Many property owners attempt to solve rat problems with store-bought traps or poison. Unfortunately, these solutions rarely address the root cause.
Common DIY Problems:
- Catching only a few visible rats
- Missing hidden nests
- Incorrect trap placement
- Secondary poisoning risks
- Failure to seal entry points
- Rats becoming trap-shy
DIY efforts may temporarily reduce activity but often allow the infestation to continue behind walls.
