5 Most Common Winter Pests in Toronto

It would be reasonable to assume that insect activity in Toronto would subside as the temperature dropped and the snowfall totals climbed. While wasps, mites, and other pests are more noticeable in the summer, the approach of winter can also pose a significant challenge in pest management.

Many insects, rodents, and humans seek the warmth of our homes and other places when the weather becomes chilly.

Today, Pestong Pest Control will discuss some pests that building and house owners should be alert of this winter. 


Cockroaches are widespread and can even be found in Ontario, Canada. Because there are more than 4,100 species of cockroaches in the world, you may be concerned about an infestation.

The good news is that, in Toronto, only a small number of cockroach species are considered serious problems. In particular, these are:

  • German Cockroach
  • Brown-Banded Cockroach
  • Oriental Cockroach
  • Pennsylvania Wood Cockroach

Cockroaches are frequent winter pests in Canada because of our chilly weather.

Although cockroaches come in many different species, some of which can even produce their antifreeze, they prefer the warmth of human dwellings. Cockroaches are a pest that will seek to penetrate your home in search of food and refuge as the temperature drops below freezing, and food becomes scarce. Most commonly, they get in through human-carried items like bags and garbage cans, or they find a way to bypass doors and windows.

Cockroaches in the winter are problematic because they are sociable pests. This implies that if you locate one cockroach removal toronto, you may expect to find many more throughout your house or office. Even if you’ve only seen one cockroach in your home, it’s still a good idea to get pest treatment because these insects can reproduce rapidly (up to over 300 new roaches in a year). If you ignore them, they may contaminate your food and spread disease to others.


Fleas can be a problem year-round, not just in the summer when you and your pet spend more time outdoors.

Fleas, like cockroaches, aren’t big fans of the winter’s chill since it hampers their ability to multiply and often kills the adult flea population. Nonetheless, it’s not the fleas outside that are the issue; rather, it’s the fleas within your home.

In late autumn, as temperatures drop, many adult fleas seek shelter indoors, where they will lay eggs and multiply. Fleas can jump up to 150 times their height, making them excellent jumpers and a common pest entryway.

Even though fleas are more interested in attacking animals than people, eliminating them from home is still a top responsibility. Due to this, your pet’s immune system might be severely compromised by flea bites.

Bed Bugs

There is an established problem with bed bugs in Canadian apartment and condo buildings, particularly in major metropolises like Toronto.

Remember to look out for anything that might have six legs. Adult bed bugs are less than a quarter of an inch long and are typically nocturnal and active at night, making them difficult to spot before they bite. As luck would have it, bed bug bites don’t spread disease, but they can leave itchy, red, and painful markings on your skin.

The name “bed bug” comes from these insets, which feed mostly on human blood. They have been spotted in picture frames, wallpaper, and even vehicles, so don’t assume they only inhabit your bed.

House Mice

Not all pests are bugs. Rodents like house mice are among the worst pests. House mice came from Central Asia and expanded across Canada and the US.

House mice can be a nuisance and health risk. Given their resemblance to pet mice, house mice may seem harmless. They enjoy eating cereal, bread, and other grain products and easily spread germs.

House mice breed quickly for mammals, like many bugs. A female house mouse has over 6 babies every three weeks, totaling 35 per year. Before house mice multiply and destroy your home and health, call a pest control toronto professional.

House mice are nocturnal, making them hard to trap despite their numbers. Droppings chew marks, and concealed tunnels in walls and floors can indicate their presence.


In the dead of winter, rodents like house mice and rats seek shelter in your home or place of business.

The Norway Rat is a prevalent nuisance that may readily invade many unprotected homes in Canada. Norway rats are eight inches long, making them visible in broad daylight. This makes them a lot easier to spot than a house mouse.

Norway rats are omnivores that will happily consume any food they find in your home. Dog food is a particular favorite of theirs. Since many people put their dog’s food down on the floor in an open dish, this can be a problem. 

Rats are notorious for their gnawing ability, which may cause significant structural damage to your house, and they are also a hygienic nuisance because they carry disease. If you do nothing, their numbers will rise, and you, your loved ones, and your customers will be at greater risk of contracting a deadly disease.


Unfortunately, many outdoor pests survive the pest control Toronto winter by making their way indoors, which may even harm your property. Nonetheless, they are avoidable and even eliminable. To get rid of the bug, you should contact a pest control agency in Canada. If you think these critters have made their way onto your property, we’ll send in pest control experts to take care of the problem.
