When winter arrives in Scarborough, temperatures drop, sidewalks freeze, and families retreat indoors to stay warm. But humans aren’t the only ones looking for heat and shelter — pests are too. From mice squeezing into wall gaps to cockroaches invading kitchens, winter becomes the peak season for household infestations.
Homeowners often assume pests are only a warm-weather problem, but in reality, winter drives insects and rodents inside more aggressively than any other season. This makes winter the most critical time to invest in a residential pest control service provided by a trusted pest control company in Scarborough.
Scarborough faces a mix of:
● Harsh cold winds from Lake Ontario
● Below-freezing nighttime temperatures
● Long periods of snow and ice
● Wet, damp weather around the home’s foundation
This combination creates an environment where pests cannot survive outdoors. When the temperature drops below 5°C, many insects and rodents instinctively search for indoor spaces with:
● Heat
● Moisture
● Food sources
● Hiding spots
Your home becomes the perfect survival zone for them.
This shift in pest behaviour is the biggest reason demand for a residential pest control service in Scarborough spikes every winter.
As homes contract in cold weather, tiny openings begin to form around:
● Window frames
● Door seals
● Exterior vents
● Utility pipe entry points
● Roof eaves
● Foundation cracks
Rodents can squeeze through holes the size of a dime.
Cockroaches and spiders slip through cracks barely visible to the naked eye.
Once inside, pests quickly locate warm hiding places such as:
● Basements
● Attics
● Laundry rooms
● Kitchens
● Furnace rooms
● Storage closets
A single entry point is all they need, which is why professional pest control inspection is so important during winter.
Your heating system turns your home into a cozy, climate-controlled environment that pests love. Rooms that stay consistently warm help pests:
● Reproduce faster
● Survive longer
● Spread into new parts of your home
Many insects slow down or die in cold conditions, but when kept warm, their breeding cycle continues uninterrupted through the entire winter.
Mice and rats, for example, breed year-round indoors. One pregnant female mouse can produce up to 60 babies in a single winter — creating a full infestation before spring arrives.
During winter, natural food sources like insects, plants, garbage, and outdoor crumbs become scarce. To survive, pests begin searching for:
● Easy access to food
● Consistent water supply
● Shelter from predators
Your home provides all three.
Food left out overnight, crumbs under appliances, or even pet food can quickly attract winter pests. That’s why a winter-season residential pest control service focuses heavily on sanitation and indoor food-prevention strategies.
Winter doesn’t just increase pest activity — it changes which pests become the biggest threat.
The #1 winter pest in Scarborough.
They enter to escape the cold and breed aggressively indoors.

Though mostly harmless, spiders enter homes seeking warmth and insects to feed on.

Carpenter ants, in particular, nest in moist wood.
Signs:
● Ant trails in the kitchen

A professional pest control company can identify which pests are active and create a winter-specific treatment plan.
Pests entering in winter often stay:
● Behind walls
● Inside insulation
● Under flooring
● In attic beams
● Behind heating ducts
Because homeowners spend more time indoors during winter, pests have constant access to:

● Water sources
This means infestations grow faster and become harder to eliminate without professional help.
