We have discussed the top 5 household pests in Canada, the harm they can do, ways to stop them, and how to prevent them. After going through our detailed analysis, you can easily prevent pests from invading your house. 

Ants

Ants are among the most common household pests in Canada. Usually, especially in the spring and summer, they break into homes to find food and water. They can easily enter through tiny gaps or cracks in doors and windows because of their small size.

Common Types in Canada

• Carpenter Ants: These big, black ants can damage the structures of your house because they build their nests in wood.


• Pavement Ants: Small brown or black ants called pavement ants which frequently found in restrooms and kitchens.


• Pharaoh Ants: These pale yellow ants build their nests in warm, humid spaces within houses.

Signs of an Infestation

• Ant trails that are visible marching along walls or floors.


• stacks of frass (for carpenter ants) or sawdust


• At night, there are rustling noises inside the walls.

Risks and Damage

• Carpenter ants hollow out wood, which can damage or weaken the furniture of your home.


• Certain species contaminate food by stepping on surfaces that are contaminated by bacteria.


• It will be difficult to eradicate the colony of ants once it establishes indoors. 

Prevention and Control

• You must seal all openings, such as windows, doors, and foundation cracks.


• Food should be kept in airtight containers.


• You should reduce indoor moisture and fix leaking pipes.


• You can use natural deterrents such as citrus or vinegar, or ant baits.


• You should contact a pest control expert if there are recurring infestations.

Mice and Rats

Rodents are prevalent during the colder months. They seek food and warmth indoors. Attics, basements, and walls are prime targets for rats and mice. They can enter through openings as small as a dime for mice or a quarter for rats.

Common Species in Canada

• House mice: They are tiny, grey rodents that procreate quickly indoors.


• Norway rats: They are larger brown rats that dig burrows near basements and foundations.


• Roof rats: They are nimble climbers that build their nests in trees and attics.

Signs of an Infestation

• If you see drops (dark, pellet-shaped), it denotes the presence of rats.


• Food packaging or wiring that has been shredded


• You might notice the sounds of scratching on the ceilings or walls.


• They gather nesting materials, such as fabric or shredded paper.

Risks and Damage

• Their presence makes the surface and food contaminated.


• Disease transmission, including Salmonella and Hantavirus.


• They damage structures by nesting and burrowing.

Prevention and Control

• You must close off spaces around pipes, vents, doors, and foundation fissures.


• Trash should be kept in sealed containers.


• You should remove any clutter that could serve as a hiding place for rodents.


• You can use ultrasonic repellents. Apart from this, you can set traps.


• It is advisable to speak with a certified rodent control specialist about more extensive infestations.

Cockroaches

Cockroaches are frequently found in basements, bathrooms, and kitchens because they prefer warm, humid spaces. Once they establish a foothold indoors, they are challenging to eradicate due to their nocturnal nature and exceptional resilience.

Common Species in Canada

• German Cockroach: German cockroaches are tiny, light brown, and prolific breeders that are frequently found indoors.


• American Cockroach: The larger, reddish-brown American cockroach is usually found in basements and sewers.

Signs of an Infestation

Prevention and Control

• Immediately fix leaks and get rid of sources of moisture.


• You should close off openings and crevices.


• You can use cockroach bait stations or sticky traps.


• It is advisable to think about hiring a professional exterminator for moderate to severe infestations.

Cluster Flies

In Canadian homes, cluster flies are a frequent annoyance, especially during the fall and early spring. They prefer warm places to food, unlike houseflies. In the winter, they frequently hibernate inside walls or attics, and during warm spells, they come out in great numbers.

Identifying Features

Prevention and Control

• Putting in door sweeps and insect screens can make the change.


• You can vacuum and get rid of flies right away.


• It is advisable to utilize insecticidal dust or fly traps in attics.


• For excessive infestations, you must contact a pest control business.

Spiders

Even though the majority of spiders in Canada are not dangerous, their presence can be unnerving. Usually, especially in the fall, they enter homes in search of food (other insects) or cover.

Common Species in Canada

• Common House Spider: They create untidy webs in basements and corners.


• Wolf Spider: This type is large and hairy and usually found on walls or floors.


• Cellar spiders: They are also known as "Daddy Long Legs" and are thin-legged and found in garages and basements.

• If you see them often. 


• Presence of egg sacs (small, white, cotton-like balls)

Risks and Damage

• Except for black widow, bites are uncommon and typically harmless.


• Their presence may indicate more serious insect issues.

Prevention and Control

• You should clean frequently and eliminate clutter.


• Reducing outdoor lighting can be significant since lighting draws insects and spiders.


• Immediately close the gaps around windows and doors.


• You have to remove the webs manually


• It is advisable to use eucalyptus and peppermint essential oils as natural deterrents.


• You should contact a pest control professional immediately if there are any venomous species.

Bonus Pest Mentions

• Bedbugs: Bedbugs can be found in soft furnishings, mattresses, and hotel rooms.
