Introduction
Ontario homeowners face pest issues year-round due to seasonal weather changes, dense
urban housing, and aging infrastructure. From ants in summer to rodents seeking warmth in
winter, pests are not just a nuisance—they can pose health, hygiene, and property risks.
Understanding common pests and knowing when to seek professional help is key to maintaining
a safe home.
This guide breaks down the most common household pests in Ontario and explains safe,
effective ways to manage them.
- Ants
Why they appear:
Ants are attracted to food sources, moisture, and accessible entry points. Kitchens, pantries,
and bathrooms are common problem areas.
Risks:
While most ants are not dangerous, they contaminate food and can spread rapidly if nests are
not addressed.
What helps:
● Sealing cracks and entry points
● Keeping food sealed and surfaces clean
● Professional treatment if colonies persist or return repeatedly - Cockroaches
Why they appear:
Cockroaches thrive in warm, humid environments with easy access to food and water.
Risks:
They are known to carry bacteria and can worsen asthma and allergies, especially in children.
What helps:
● Reducing moisture and clutter
● Avoiding DIY sprays that scatter infestations
● Professional control to eliminate nesting areas - Bed Bugs
Why they appear:
Bed bugs spread through luggage, furniture, and shared living spaces—not poor hygiene.
Risks:
They cause itchy bites, sleep disruption, and emotional stress. Infestations spread quickly if
untreated.
What helps:
● Early identification
● Avoiding home remedies that worsen spread
● Targeted professional treatment - Rodents (Rats & Mice)
Why they appear:
Rodents seek warmth and food during colder months and enter through very small gaps.
Risks:
● Property damage from chewing
● Food contamination
● Disease transmission
What helps:
● Sealing entry points
● Removing food sources
● Humane and controlled removal by professionals - Spiders
Why they appear:
Spiders follow prey insects into homes and often hide in basements, garages, and corners.
Risks:
Most spiders in Ontario are harmless, but their presence often indicates other pest activity.
What helps:
● Reducing insect populations
● Sealing cracks and vents
● Professional inspection if numbers increase - Bees and Wasps
Why they appear:
They build nests near roofs, attics, and outdoor structures.
Risks:
Stings can be dangerous for people with allergies and nests near entrances increase risk.
What helps:
● Avoid disturbing nests
● Safe, regulated removal by trained professionals
Why Professional Pest Control Matters
DIY solutions often treat visible pests but fail to address nests, breeding cycles, or entry points.
Professional pest control focuses on:
● Proper identification
● Safe treatment methods
● Long-term prevention
Companies like Telos Pest Control provide residential pest solutions using licensed technicians
and structured treatment plans.
Conclusion
Pests are a common reality in Ontario homes, but infestations don’t have to become long-term
problems. Early action, proper prevention, and professional support help protect your home,
health, and peace of mind.
If pests are persistent or spreading, professional inspection is the safest next step.
